Compile Guide and FAQ

This guide may help you successfully compile Eggdrop. Suggestions are by various contributors. If you think something should be added, please send an e-mail to bugs@eggheads.org. Note that in this document, text between a '<' and a '>' should be replaced (without the '<' and '>').

NOTE: This is not a 'quick install' guide. See the INSTALL file for basic setup information. This is intended to help you compile the bot on uncommon operating systems, or work past problems encountered during compile.

Compile Guide

This will tell you how to compile Eggdrop on various operating systems. If you have gotten Eggdrop to compile on an operating system not listed here, please let the development team know how, at eggdev@eggheads.org. Please tell us what, if any, special steps were required to compile the bot. Also, any compiler warnings/etc, and the 'config.log' and 'config.h' files would be helpful. The development team does not have access to the resources needed to test portability on uncommon operating systems, so your help is greatly appreciated.

A. Standard compile process (32-bit Linux, FreeBSD, NetBSD, OpenBSD, etc.)

> 1. Type './configure' from the Eggdrop directory. Some of the options that can be given to ./configure are explained below.

>    - --enable-strip
>      If you want to create a smaller binary, you can use this option. HOWEVER, this will remove debugging symbols and make bug reports almost completely useless, and is not recommended. If disk space is very limited, however, it might help to enable this.
>    - --disable-tcl-threads
>      This disables support for Tcl threads.
>    - --with-tcllib
>    - --with-tclinc
>      See E. Tcl Detection and Installation below (at the end of this compile guide).
> 2. Type either 'make config', or 'make iconfig' to determine which modules will be compiled.
> 3. Type 'make' from the Eggdrop directory, or to force a statically linked module bot, type 'make static'. Otherwise, the Makefile will use whatever type of compile the configure script determined your system will support. Dynamic is always the better way to go if possible. You can force a dynamic build with 'make eggdrop'. There are also the 'debug' and 'sdebug' (static-debug) options, which will give more detailed output on a crash. This will help the development team track down the crash and fix the bug. Debug and sdebug will take a little longer to compile and will enlarge the binary a bit, but it's worth it if you want to support Eggdrop development.
> 4. Eggdrop must be installed in a directory somewhere. This is accomplished by typing 'make install'.
>    This will install the Eggdrop in your home directory in a directory called 'eggdrop' (i.e. /home/user/eggdrop).
>    If you want to install to a different directory, use:

>    >     make install DEST=<directory>

>    For example:

>    >     make install DEST=/home/user/otherdir

B. HP-UX B.11.*

> Follow the standard compile process in Section A. To compile dynamically (with module support), use 'make eggdrop' instead of 'make'.

> During a linking in a dynamic build, you may experience an error such as:

> >     gcc -pipe -fPIC -shared -o ../eggdrop bg.o botcmd.o botmsg.o botnet.o
> >     chanprog.o cmds.o dcc.o dccutil.o dns.o flags.o language.o match.o
> >     main.o mem.o misc.o misc_file.o modules.o net.o rfc1459.o tcl.o
> >     tcldcc.o tclhash.o tclmisc.o tcluser.o userent.o userrec.o users.o
> >     -L/usr/local/lib -ltcl8.4 -lm -ldld -lnsl md5/md5c.o compat/*.o `cat
> >     mod/mod.xlibs`
> >     /usr/ccs/bin/ld: DP relative code in file bg.o - shared library must be
> >     position independent. Use +z or +Z to recompile.
> >     collect2: ld returned 1 exit status
> >     *** Error exit code 1

> If you know the cause of this error, please contact the Eggheads Development Team at eggdev@eggheads.org.

> Note that on HP-UX, the SHLIB_PATH environment variable should be used instead of LD_LIBRARY_PATH.

C. Ultrix

> There are some known problems with 'make' and Eggdrop on Ultrix systems. We recomend using 'gmake' (GNU make) for this reason, as in the steps below.

> If your system does not have 'gmake', you can download it from:

> > http://ftp.gnu.org/pub/gnu/make/

> It can be installed in your home directory, as with Tcl, but that is beyond the scope of this document. Read the INSTALL file that comes with gmake.

> Following these steps should work:

> > 1. Depending on what shell your using:
> >    bash/ksh:

> >    >     export LD_LIBRARY_PATH=<path to DIRECTORY containing Tcl library>:${LD_LIBRARY_PATH}

> >    csh/tcsh/tclsh:

> >    >     setenv LD_LIBRARY_PATH <path to DIRECTORY containing Tcl library>:${LD_LIBRARY_PATH}

> > 2. Run the following command from your Eggdrop compilation directory (this is all one command):

> >    >     sh5 ./configure --with-tclinc='<full path to tcl.h>' --with-tcllib='<full path to Tcl library>'

> > 3. Type 'gmake config' or 'gmake iconfig' to configure modules.
> > 4. Type 'gmake'. If you experience problems during linking, or while building modules, try using 'gmake static', for a static build, instead.
> > 5. To install Eggdrop, type 'gmake install'.
> >    This will install the Eggdrop in your home directory in a directory called 'eggdrop' (i.e. /home/user/eggdrop).
> >    If you want to install to a different directory, use:

> >    >     gmake install DEST='directory'

> >    For example:

> >    >     gmake install DEST=/home/user/otherdir

D. Mac OS X

> Follow the standard compile process in Section A. To compile dynamically (with module support), use 'make eggdrop' instead of 'make'.

> To get third-party modules to compile, you may need to edit the module's Makefile and add "$(XLIBS) $(MODULE_XLIBS)" to the end of the ../../../MODULE.$(MOD_EXT) target's $(LD) line.

> For example:

> >     ../../../mymodule.$(MOD_EXT): ../mymodule.o
> >     $(LD) -o ../../../mymodule.$(MOD_EXT) ../mymodule.o
> >     $(STRIP) ../../../mymodule.$(MOD_EXT)

> Would become:

> >     ../../../mymodule.$(MOD_EXT): ../mymodule.o
> >     $(LD) -o ../../../mymodule.$(MOD_EXT) ../mymodule.o $(XLIBS) $(MODULE_XLIBS)
> >     $(STRIP) ../../../mymodule.$(MOD_EXT)

> If you notice a module that requires these changes, it would probably be a good idea to let the module's developer know, so it can be fixed.

> Note that on Mac OS X, the DYLD_LIBRARY_PATH environment variable should be used instead of LD_LIBRARY_PATH.

E. AIX

> Follow the standard compile process in Section A. To compile dynamically (with module support), use 'make eggdrop' instead of 'make'.

> Note that on AIX, the LIBPATH environment variable should be used instead of LD_LIBRARY_PATH.

F. IRIX

> Follow the standard compile process in Section A. To compile dynamically (with module support), use 'make eggdrop' instead of 'make'.

> Note that on IRIX, the LD_LIBRARYN32_PATH and LD_LIBRARY64_PATH environment variables should be used instead of LD_LIBRARY_PATH.

G. Solaris / SunOS

> Follow the standard compile process in Section A. To compile dynamically (with module support), use 'make eggdrop' instead of 'make'.

> Note that on Solaris / SunOS, the LD_LIBRARY_PATH_32 and LD_LIBRARY_PATH_64 environment variables may need to be set instead of (or in addition to, to be safe) LD_LIBRARY_PATH.

H. Cygwin / Windows

> To compile and install Eggdrop on windows, preform the steps listed below.

> > 1. Download and install Cygwin (http://www.cygwin.com). Make sure to install things like GCC, zlib, minires, autoconf, and automake. DO NOT install the Tcl provided by Cygwin's installer. After installing, open the Cygwin bash prompt.
> > 2. Download and install TCL 8.4.1. You can get Tcl for Cygwin at http://prdownloads.sourceforge.net/windrop/tcl-8.4.1.tar.gz. Extract this to the Cygwin root directory:

> >    >     cd /
> >    >     tar -zxf tcl-8.4.1.tar.gz

> > 3. Download Eggdrop from www.geteggdrop.com to your home directory. This is usually something like 'C:\cygwin\home\<username>\'. After downloading, extract the Eggdrop tarball:

> >    >     tar -zxf eggdrop1.6.18.tar.gz

> > 4. Run './configure --enable-strip'. Debugging information under Windows is basically useless to the development team, and thi will reduce the size of your Eggdrop binary.
> > 5. Type either 'make config', or 'make iconfig' to determine which modules will be compiled.
> > 6. Compile the bot using 'make eggdrop'.
> > 7. Install the bot by typing 'make install DEST=<install path>'.
> >    For example:

> >    >     make install DEST='C:/eggdrop/'

> >    Make sure to enclose the destination directory/folder in single quotes (''), especially if it contains spaces.
> > 8. Preform the following commands:

> >    >     cd 'C:/<install path>/' (example: cd 'C:/eggdrop')
> >    >     rm modules
> >    >     rm eggdrop.exe
> >    >     mv eggdrop.exe-1.6.18 eggdrop.exe
> >    >     mv modules-1.6.18 modules

> > 9. Create a 'lib' directory and copy needed libraries using the following commands. This assumes that you installed your Eggdrop in 'C:\eggdrop'. If you chose a different installation path, replace 'C:/eggdrop' in the following steps with your installation directory, replacing all '\'s with '/'s.

> >    >     cp /bin/cygwin1.dll 'C:/eggdrop'
> >    >     cp /usr/local/bin/tcl84.dll 'C:/eggdrop'
> >    >     cp /usr/local/bin/tclpip84.dll 'C:/eggdrop'

> >    >     mkdir C:/eggdrop/lib
> >    >     cp -r /usr/local/lib/dde1.2 'C:/eggdrop/lib'
> >    >     cp -r /usr/local/lib/reg1.1 'C:/eggdrop/lib'
> >    >     cp -r /usr/local/lib/tcl8.4 'C:/eggdrop/lib'

> >    >     cp /bin/cygz.dll 'C:/eggdrop' (if you selected compress.mod)
> >    >     cp /bin/cygminires.dll 'C:/eggdrop' (if you selected dns.mod)

I. Tcl Detection and Installation

> If ./configure does not correctly detect the location of your Tcl library and header file, or if you experience errors related to Tcl during linking, preform these steps:

> > 1. Depending on what shell your using:
> >    bash/ksh:

> >    >     export LD_LIBRARY_PATH=<path to DIRECTORY containing Tcl library>:${LD_LIBRARY_PATH}

> >    csh/tcsh/tclsh:

> >    >     setenv LD_LIBRARY_PATH <path to DIRECTORY containing Tcl library>:${LD_LIBRARY_PATH}

> >    Note that some OS;'s use a different environment variable to tell ld where to look for a library. See the notes for your specific OS above (if applicable).
> > 2. Run the following command from your Eggdrop compilation directory (this is all one command):

> >    >     ./configure --with-tclinc='<full path to tcl.h>' --with-tcllib='<full path to Tcl library>'

> > 3. Continue compiling the bot as outlined in Section A, starting with 'make config'.

> If you do not have Tcl installed on your system, you can compile it in your /home directory. Download Tcl from Tcl's SourceForge project page at http://www.sourceforge.net/projects/tcl/, or from ActiveState at ftp://tcl.activestate.com/pub/tcl/tcl8_4/. Read Tcl's README file for help with compiling and installing it. After you compile Tcl, follow the steps above to allow Eggdrop to detect Tcl.

1. I get lots of warnings.

> Warnings do not necessarily mean anything bad. As long as the compile completes, there is really nothing to worry about. Generally, we try to avoid warnings. We try to fix the warnings we are aware of. If you experience warnings, you can let us know by e-mailing bugs@eggheads.org. If you feel like fixing them yourself, please do so and send us a patch (as described in Patch Howto). Thanks.

2. I get a 'strip terminated with signal 6' error during compile/install.

>     collect2: strip terminated with signal 6 [IOT/Abort trap]

>     *** Exit 1
>     Stop.
>     *** Exit 1
>     Stop.

> Don't use the --enable-strip ./configure option.

3. 'DIR' undeclared (and a whole bunch of others) (AIX 4)

>     gcc -c -O2 -fno-strength-reduce -I.. -DHAVE_CONFIG_H  filedb.c
>     filedb.c: In function `filedb_update':
>     filedb.c:209: `DIR' undeclared (first use this function)
>     filedb.c:209: (Each undeclared identifier is reported only once
>     filedb.c:209: for each function it appears in.)
>     filedb.c:209: `dir' undeclared (first use this function)
>     filedb.c:209: parse error before `*'
>     filedb.c:217: warning: assignment makes pointer from integer without a cast
>     filedb.c:218: `name' undeclared (first use this function)
>     filedb.c:218: dereferencing pointer to incomplete type
>     filedb.c:220: dereferencing pointer to incomplete type
>     filedb.c:220: dereferencing pointer to incomplete type
>     filedb.c:224: dereferencing pointer to incomplete type
>     filedb.c:224: dereferencing pointer to incomplete type
>     filedb.c:225: dereferencing pointer to incomplete type
>     filedb.c:230: `s' undeclared (first use this function)
>     filedb.c:231: `st' undeclared (first use this function)
>     filedb.c:232: `fdb' undeclared (first use this function)
>     filedb.c:232: `where' undeclared (first use this function)
>     filedb.c:237: `fdb1' undeclared (first use this function)
>     filedb.c:253: warning: assignment makes pointer from integer without a cast
>     make: The error code from the last command is 1.

> The configure script didn't detect that this particular system had dirent.h and sys/dir.h. The solution is to add -DHAVE_DIRENT_H -DHAVE_SYS_DIR_H to the Makefile's CFLGS line:

> >     CFLGS = -DHAVE_DIRENT_H -DHAVE_SYS_DIR_H

4. 'fd_set' undeclared (and a whole bunch of others) (AIX 4)

>     gcc -c -O2 -fno-strength-reduce -I.. -DHAVE_CONFIG_H -DHAVE_DIRENT_H -DHAVE_SYS_DIR_H net.c
>     net.c: In function `sockread':
>     net.c:390: `fd_set' undeclared (first use this function)
>     net.c:390: (Each undeclared identifier is reported only once
>     net.c:390: for each function it appears in.)
>     net.c:390: parse error before `fd'
>     net.c:396: `fd' undeclared (first use this function)
>     make: The error code from the last command is 1.

> Again, this seems that one of configure's components (sed, awk, or something along those lines) is broken, and configure failed to detect that this system needed sys/select.h. The solution is to add -DHAVE_SYS_SELECT_H to the Makefile's CFLGS line:

> >     CFLGS = -DHAVE_DIRENT_H -DHAVE_SYS_DIR_H -DHAVE_SYS_SELECT_H

5. Unresolved or undefined symbols: ldclose, ldopen, ldnshread (AIX 3)

>     cc -s -o eggdrop chan.o chanprog.o chanset.o cmds.o dcc.o dccutil.o
>     filedb.o fileq.o files.o gotdcc.o hash.o main.o match.o mem.o misc.o
>     mode.o msgcmds.o msgnotice.o net.o tandcmd.o tandem.o tcl.o tclhash.o
>     userrec.o users.o -L/home2/f/foster/lib -ltcl7.5 -lm
>        0706-317 ERROR: Unresolved or undefined symbols detected:
>                        Symbols in error (followed by references) are dumped to the load map.
>                        The -bloadmap:<filename> option will create a load map.
>        .ldclose
>        .ldopen
>        .ldnshread
>        make: 1254-004 The error code from the last command is 8.

> Apparently, what is happening is a library called ld is required. Either configure doesn't know it is needed, it simply can't find it, or maybe this is a unique case. The solution is to have ld linked in with the final binary.

> Edit your Makefile and find the line that looks something like this:

> >     GMAKE = ${MAKE} 'CC=cc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl7.5.a'\
> >             'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS= -L/home2/f/foster/lib -ltcl7.5 -lm'\
> >             'TCLLIB=${TCLLIB}' 'RANLIB=ranlib' 'STRIP=-s'

> Add in -lld into the XLIBS assignment, like this:

> >     GMAKE = ${MAKE} 'CC=cc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl7.5.a'\
> >             'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS=-lld -L/home2/f/foster/lib -ltcl7.5 -lm'\
> >             'TCLLIB=${TCLLIB}' 'RANLIB=ranlib' 'STRIP=-s'

6. Unsatisfied symbols 'shl_findsym' and 'shl_load' (HP-UX 9)

>     gcc -s -o eggdrop chan.o chanprog.o chanset.o cmds.o dcc.o
>     dccutil.o filedb.o fileq.o files.o gotdcc.o hash.o main.o match.o
>     mem.o misc.o mode.o msgcmds.o msgnotice.o net.o tandcmd.o tandem.o
>     tcl.o tclhash.o userrec.o users.o -L/home/hltran/tcl/lib -ltcl7.5 -lm
>        /bin/ld: Unsatisfied symbols:
>           shl_findsym (code)
>           shl_load (code)
>        collect2: ld returned 1 exit status
>        *** Error code 1
>        Stop.

> Upgrade to a later version of Tcl. The following should also work.

> Edit your Makefile and find the line that looks something like this:

> >     GMAKE = ${MAKE} 'CC=gcc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl7.5.a'\
> >             'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS= -L/usr/local/lib -ltcl7.5 -lm'\
> >             'TCLLIB=${TCLLIB}' 'RANLIB=:' 'STRIP='

> Add in -ldl into the XLIBS assignment, like this:

> >     GMAKE = ${MAKE} 'CC=gcc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl7.5.a'\
> >             'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS=-ldl -L/usr/local/lib -ltcl7.5 -lm'\
> >             'TCLLIB=${TCLLIB}' 'RANLIB=:' 'STRIP='

7. Compile stops at the last minute with "ld fatal signal 11"! (Linux)

> This seems to be caused by a non-ELF Tcl library binary, and the compiler doesn't seem to like it. Download and install Tcl in your home directory using the steps in E. Tcl Detection and Installation in the Compile Guide above.

8. Undefined references in net.o (SunOS)

>                    First
>     Undefined    Referenced
>      Symbol       In file

>     socket          net.o
>     gethostbyname   net.o
>     accept          net.o
>     bind            net.o
>     setsockopt      net.o
>     gethostbyaddr   net.o
>     getsockname     net.o
>     gethostname     net.o
>     listen          net.o
>     connect         net.o
>     ld: fatal: Symbol referencing errors. No output written to eggdrop

> This seems to be caused by a few libraries not being detected by the auto-configure script; it is relatively easy to fix. Edit your Makefile. Note that yours may be slightly different than this one when it comes to the Tcl library, but here is the way it probably is:

> >     GMAKE = ${MAKE} 'CC=gcc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl.a'\
> >             'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS= -L/usr/local/lib -ltcl -lm'\
> >             'TCLLIB=${TCLLIB}' 'RANLIB=:' 'STRIP='

> Here is what you need to change it to:

> >     GMAKE = ${MAKE} 'CC=gcc' 'AWK=awk' 'OBJS=${OBJS}' 'TCLLIBFN=tcl.a'\
> >             'CFLAGS=${CFLAGS}' 'XREQ=${XREQ}' 'XLIBS=lsocket -ldl -lnsl -L/usr/local/lib -ltcl -lm'\
> >             'TCLLIB=${TCLLIB}' 'RANLIB=:' 'STRIP='

> You are adding three libraries to be linked in: socket, dl, and nsl. This will resolve the net.o errors.

9. I experience problems starting the configure script (AIX/various)

> If you receive file descriptor or bad interpreter errors when attempting to run the configure script, try running 'sh configure' or 'bash configure' instead of './configure'. This problem seems to show up on many AIX machines.

10. I get a 'make: Permission denied' error when I type 'make config' or 'make' (FreeBSD / *BSD)

> This is caused by a bug in FreeBSD (and possibly other BSDs as well). A simple 'cd .', or changing to a different directory and then changing back, usually fixes this.
