3 years ago Looks like you're building with a 32-bit perl on a 64-bit user space. What does

Yes, I'm trying to build 32 bit on a 64 bit OS.
Here's your problem:
Compiler: cc='gcc', ccflags ='-D_REENTRANT -D_GNU_SOURCE -DUSE_SITECUSTOMIZE -DPERL_RELOCATABLE_INCPUSH -fno-merge-constants -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64',
I guess you don't have a 32-bit gcc installed so that gcc will invoke your "native" 64-bit compiler (which produces 64-bit objects
by default). I doubt that you ever built any XS perl module in this setting. The easiest solution is to patch
/opt/ActivePerl-5.16/.../Config.pm and add -m32 to the value of cflags.

3 years ago Thank you. I updated cpan, installed cpanm and other modules just fine, but I'm sure if that built modules with C code. I thought so, but I might be wrong. The installed gcc does build 32 and 64 bit projects (I tried it) but I'm not really an expert in picking compiler flags.
I searched for ccflags in both .pl and .pm files and the most interesting are:
In /opt/ActivePerl-5.16/lib/ActivePerl/Config.pm I see $^O eq OS checks for many kernels except Linux specifically.
It was quite involved and I didn't change it. I can paste it if you need to see it.
In /opt/ActivePerl-5.16/lib/Config_heavy.pl looked more promising, with a clearly stated ccflags value.
I changed /opt/ActivePerl-5.16/lib/Config_heavy.pl like this
ccflags='-D_REENTRANT -D_GNU_SOURCE -DUSE_SITECUSTOMIZE -DPERL_RELOCATABLE_INCPUSH -fno-merge-constants -fno-strict-aliasing -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64' -m32
That's the only change I made. I'm not sure If I also need to add it to ccflags_nolargefiles
our $Config_SH_expanded = "\n$_" . << 'EOVIRTUAL';
ccflags_nolargefiles='-D_REENTRANT -D_GNU_SOURCE -DUSE_SITECUSTOMIZE -DPERL_RELOCATABLE_INCPUSH -fno-merge-constants -fno-strict-aliasing -pipe '
ldflags_nolargefiles=''
libs_nolargefiles='-lnsl -lgdbm -ldb -ldl -lm -lcrypt -lutil -lpthread -lc'
libswanted_nolargefiles='sfio socket inet nsl nm ndbm gdbm dbm db malloc dl dld ld sun m crypt sec util pthread c cposix posix ucb BSD gdbm_compat'
EOVIRTUALand to ccflags_uselargefiles.
ccflags_uselargefiles='-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64'But the build still fails

3 years ago OK, let's back off a bit: what are you trying to achieve? I assume you're trying to build executables (via PAR::Packer's pp)
with a 32-bit perl distribution. So you can only expect to generate 32-bit executables. Why do you need these?
AgostinoSturaro
commented
3 years ago Good question. I have a set of small Perl tools for system diagnostics, and I can't go install a custom Perl interpreter and the needed modules on all the target endpoints. I mostly need to target RHEL/CentOS >=6 and 64 bits, but there are a few 32 bit CentOS 6 and 32 bit Ubuntu LTS, possibly some SuSe as well (quite a mix, I know). I still need to care for the 32 bit hosts and I was hoping to build everything in 32 bits and run that on 64 bit systems as well.
If I can build a 32 bit executable on a 32 bit CentOS 6, can I expect it to work on a 64 bit CentOS 8? If so, that might be fine. If it worked on Ubuntu (and Suse) as well, that would be really nice.

Should be doable, but probably takes some more tweaks to compiler and linker flags to achieve. In general, one should build on the same platform as the target.
If I can build a 32 bit executable on a 32 bit CentOS 6, can I expect it to work on a 64 bit CentOS 8?
That should work. Of course the 64-bit systems must have the required 32-bit system libs (libc.so, libm.so etc, but nothing perl specific) installed. There shouldn't be any GLIBC versioning problems as your building on older systems.

3 years ago The installation worked on CentOS 6.10 32 bit and ActivePerl 5.16.3 x86. ODBC stuff does not seem to get wrapped correctly though. I'll open a separate ticket for that once I can get more information. Thank you.
I'm trying to install PAR::Packer on an ActivePerl 5.16.3 x86 on a RHEL 6.10 x64. It fails to install. Here is the command prompt
Here is the content of
/root/.cpanm/work/1606926712.5624/build.logI also have an older Perl version installed, but not in PATH.
Any idea how to get this to install on the ActivePerl version? I had no problem installing cpanm there. Thank you.
