Perl: AIX compile error

flynn7312 has asked for the wisdom of the Perl Monks concerning the following question:

dear monks, i am in the process of doing a gcc build of Perl, but it wont let me through. A build with IBM's native xlc compiler is going well, but in this case gcc is necessary to not break the AIX freeware tree.

here ist the error in his full glory.

Is there any perl bugtracker where one can report this kind of errors? I dont know how to report compilation errors with perlbug.

Instead of defining a zillion options to Configure, create a Policy.sh (and save it) and work from there. `cc=gcc ccflags="-maix32 $ccflags" ...` [download] Enjoy, Have FUN! H.Merijn	[reply] [d/l]

I dont know how to report compilation errors with perlbug You can just send an email to perlbug at perl dot org, including the info you provided. Provide a suitable subject line for the email, and also mention which version of perl you're trying to build. Cheers, Rob	[reply]

From perlaix: If you choose gcc to compile 64-bit Perl then you need to add the following option. See also, article at IBM. `-Dcc='gcc -maix64'` [download] Update: Ah, it looks like you're wanting to build a 32-bit Perl. Have you tried the following configure option? `-Dcc='gcc -maix32'` [download] There is AIX Toolbox for Linux Applications. The AIX Toolbox for Linux Applications contains a wide variety of software, including but not limited to: - Application Development - gcc, g++, gdb, rpm, cvs, automake, autoconf, libtool, git, subversion, gettext - GNU base utilities - gawk, m4, indent, sed, tar, diffutils, findutils, grep, coreutils - Programming Languages - perl, python, ruby, php - System Utilities - emacs, vim, bzip2, gzip, rsync, wget, lsof, less, samba, zip, unzip - Libraries - ncurses, readline, libxml2, libyaml, libpng, libjpeg, slang, db, glib2, zlib, gtk+ - System Shells - bash, tcsh, zsh - Software Managment - YUM - Developing graphical user interface - gtk2+ - Cloud environment - cloud-init, python-swift [download] With the perl binary, included with the toolbox, one can then extract the configure options used. `/path/to/toolbox/bin/perl -V \| grep config_args` [download] Am not sure how gcc was installed. If taken from AIXTOOLS, notice the extra step after the installation. `/opt/libexec/gcc/powerpc-ibm-aix5.3.7.0/4.7.4/install-tools/mkheaders` [download] Regards, Mario	[reply] [d/l] [select]

See the man page for `getspnam` on your system. The `struct spwd` ought to be defined in `<shadow.h>`, but maybe it's different on AIX. Maybe you just need to pass `-DI_SHADOW` to gcc.	[reply] [d/l] [select]
