Problems with Embperl and AIX 5.2

John P. Gibbons Thu, 08 Jul 2004 21:16:10 -0700

Recently we've been upgrading our servers from AIX 4.3.3 to AIX 5.2 and one of the casualties has been Embperl. I've been wrestling with trying to make this work for some time now, and not being a C programmer I think I might have hit a wall.

Here's what I'm using:

AIX 5.2 IBM HTTPServer 1.3.28 mod_perl 1.29 Embperl 1.3.6 (and I've tried 2.0 with the same result, although I had to fix some syntax issues with // comments) IBM's Visual Age compiler 6.0

First things first, I have only been able to make mod_perl work when using Perl 5.8.4. Any other version, including 5.8.1 will cause a segfault in Apache. This happens both with IBM HTTPServer (which is what we want to use) and a compiled Apache. We're using APXS to configure mod_perl because we don't want to have to roll our own Apache (so we can get support from IBM) so even if a statically compiled version did work, we couldn't use.

Anyhow, once Apache and mod_perl are happy I am now stuck with Embperl not working. It compiles flawlessly with no errors but running a make test returns:

make test PERL_DL_NONLAZY=0 /appl/web/perl/bin/perl "-Iblib/lib" "-Iblib/arch" test.pl

loading... Can't load '/appl/web/compile/HTML-Embperl-1.3.6/blib/arch/auto/HTML/Embperl/Embperl.so' for module HTML::Embperl: Cannot run a file that does not have a valid format. at /appl/web/perl/lib/5.8.4/aix/DynaLoader.pm line 230. at test.pl line 1525 Compilation failed in require at test.pl line 1525. BEGIN failed--compilation aborted at test.pl line 1525.

Test terminated with fatal error
Use of uninitialized value in string ne at test.pl line 966.
make: 1254-004 The error code from the last command is 1.


Stop.

------------

I've tried this with 2.0 as well and it has the same problem.

I think it might have something to do with missing libraries as ldd on Embperl.so returns:

./blib/arch/auto/HTML/Embperl/Embperl.so needs: /usr/lib/libc.a(shr.o) Cannot findCannot find /unix /usr/lib/libcrypt.a(shr.o) I think it's saying that it can't find two libraries, but it isn't telling me which ones these are.Curiously, ldd on libperl.so has these errors as well.

libperl-584works-mp129.so needs:
        /usr/lib/libc.a(shr.o)
        /usr/lib/libbsd.a(shr.o)
        /usr/lib/librtl.a(shr.o)
Cannot findCannot find   /unix
        /usr/lib/libcrypt.a(shr.o)

Again, I'm not a C programmer so I might be way off here, but after reading through the mailing list archives ldd output is often requested when diagnosing problems so I'm including it. Here are the ldd outputs for httpd and the perl binary, in case they are of any use.

httpd:
../bin/httpd needs:
        /usr/lib/libc_r.a(shr.o)
        /usr/lib/libC.a(shr.o)
        /usr/lib/libpthread.a(shr_comm.o)
        /usr/lib/libpthread.a(shr_xpg5.o)
        /usr/lib/libdl.a(shr.o)
        /unix
        /usr/lib/libcrypt.a(shr.o)
        /usr/lib/libC.a(ansicore_32.o)
        /usr/lib/libC.a(shrcore.o)
        /usr/lib/libc.a(shr.o)
        /usr/lib/libpthreads.a(shr_comm.o)
        /usr/lib/libC.a(shr2.o)
        /usr/lib/libC.a(shr3.o)

perl:
/appl/web/perl/bin/perl needs:
        /usr/lib/libbind.a(shr.o)
        /usr/lib/libnsl.a(shr.o)
        /usr/lib/libdl.a(shr.o)
        /usr/lib/libcrypt.a(shr.o)
        /usr/lib/libc.a(shr.o)
        /usr/lib/libbsd.a(shr.o)
        /usr/lib/librtl.a(shr.o)
        /usr/lib/libpthreads_compat.a(shr.o)
        /usr/lib/libtli.a(shr.o)
        /unix
        /usr/lib/libpthreads.a(shr.o)
        /usr/lib/libc.a(pse.o)
        /usr/lib/libpthreads.a(shr_comm.o)

And here's the output of perl -V: Summary of my perl5 (revision 5 version 8 subversion 4) configuration: Platform: osname=aix, osvers=5.2.0.0, archname=aix uname='aix intranet1 2 5 000121674c00 ' config_args='-Uuselargefiles -Dprefix=/appl/web/perl' hint=recommended, useposix=true, d_sigaction=define usethreads=undef use5005threads=undef useithreads=undef usemultiplicity=undef useperlio=define d_sfio=undef uselargefiles=undef usesocks=undef use64bitint=undef use64bitall=undef uselongdouble=undef usemymalloc=n, bincompat5005=undef Compiler: cc='cc', ccflags ='-D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE -qmaxmem=-1 -qnoansialias -DUSE_NATIVE_DLOPEN -I/usr/local/include', optimize='-O', cppflags='-D_ALL_SOURCE -D_ANSI_C_SOURCE -D_POSIX_SOURCE -qmaxmem=-1 -qnoansialias -DUSE_NATIVE_DLOPEN -I/usr/local/include' ccversion='6.0.0.4', gccversion='', gccosandvers='' intsize=4, longsize=4, ptrsize=4, doublesize=8, byteorder=4321 d_longlong=define, longlongsize=8, d_longdbl=define, longdblsize=8 ivtype='long', ivsize=4, nvtype='double', nvsize=8, Off_t='off_t', lseeksize=4 alignbytes=8, prototype=define Linker and Libraries: ld='ld', ldflags =' -brtl -L/usr/local/lib' libpth=/usr/local/lib /lib /usr/lib /usr/ccs/lib libs=-lbind -lnsl -ldbm -ldl -lld -lm -lcrypt -lc -lbsd perllibs=-lbind -lnsl -ldl -lld -lm -lcrypt -lc -lbsd libc=/lib/libc.a, so=a, useshrplib=false, libperl=libperl.a gnulibc_version='' Dynamic Linking: dlsrc=dl_aix.xs, dlext=so, d_dlsymun=undef, ccdlflags=' -bE:/appl/web/perl/lib/5.8.4/aix/CORE/perl.exp' cccdlflags=' ', lddlflags=' -bhalt:4 -bM:SRE -bI:$(PERL_INC)/perl.exp -bE:$(BASEEXT).exp -bnoentry -lc -L/usr/local/lib'


Characteristics of this binary (from libperl):
 Compile-time options:

Does anyone have any idea what's going on and what I can do to fix it?

Thanks in advance!

Cheers,
