Well... it proved easier than I thought.

Here is the recipe:

CC=/usr/vac/bin/cc_r ./configure --disable-ipv6 --prefix=/usr/local --with-perl-staticlib

This will compile just fine if you edit the following file:

src/fe-common/core/printtext.h

and remove the lines 37-57 (tests for the compiler) and the closing #endif on line 116, of course.

Well, running it is far from perfect:

$ irssi
exec(): 0509-036 Cannot load program irssi because of the following errors:
0509-150 Dependent module libperl.a(libperl.o) could not be loaded.
0509-022 Cannot load module libperl.a(libperl.o).
0509-026 System error: A file or directory in the path name does not exist.

However,

$ LIBPATH=$LIBPATH:/usr/opt/perl5/lib/5.8.2/aix-thread-multi/CORE/ irssi

starts the program.

This is what I got to compile last March:

I see the *.13.svn directory as well. Need to check that. I have not worked with it much since then. Maybe the version ending in .12 is better for now.

Well I have compiled irssi - but maybe using gcc.

The way some opensource packages are developed makes porting hard. libtool often seems to get in the way.

Recently I was compiling apache2, and it failed with gcc. A bad library search path. Using xlC - older than yours though, version 8 I think, it compiled fine.

Generally, the fix is to specify environment variables to ./configure. But each package requires it's own approach. Unfortunately.

I shall be on the road the coming week, so I wont have time to look at how I built irssi myself, but I'll let you know asap.

xlC compile errors: undefined symbol (irssi/perl)

« on: November 14, 2008, 01:10:02 PM »

Hello,

this is my first post here ;-)

I have started compiling irssi on AIX 5.3 TL8 with xlC 10.1.

The following components are already compiled with exit 0:

- pkg-config-0.23
- gettext-0.17
- glib-2.19.0 # this was a hard one, I had to comment out a few lines in the code to get it working ;-)

I have problems with

irssi-0.8.13-svn (2008-11-12)

In src/perl/common, make fails with missing symbols:

Making all in perl
for dir in common irc ui textui; do cd $dir && if [ ! -f Makefile ]; then /usr/bin/perl Makefile.PL INSTALLDIRS=perl PREFIX=/usr/local; fi && (make CC="xlc_r -D_ALL_SOURCE" CCFLAGS="-D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE -qmaxmem=16384 -qnoansialias -DUSE_NATIVE_DLOPEN -DNEED_PTHREAD_INIT -q32 -D_LARGE_FILES -qlonglong -I/usr/opt/perl5/lib/5.8.2/aix-thread-multi/CORE -g" || make CC="xlc_r -D_ALL_SOURCE" CCFLAGS="-D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE -qmaxmem=16384 -qnoansialias -DUSE_NATIVE_DLOPEN -DNEED_PTHREAD_INIT -q32 -D_LARGE_FILES -qlonglong -I/usr/opt/perl5/lib/5.8.2/aix-thread-multi/CORE -g" ) && cd ..; done

ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
make: 1254-004 The error code from the last command is 8.

I have collected a few hints found on the web (including adding -bnoquiet as suggested ;-), but unfortunately, I can only test them in the evening on my machine.

As I see, this linker problem is quite common on AIX. So the real question is if there is a 'generic approach' to handling this problem.
