Hi again I inspected the rpm spec file we use to build perl and found some errors setting it to default value
config_args='-des -A ccflags=-fPIC -Dprefix=/opt/perl -Dinstallprefix=/opt/perl' Now mod_perl compiles fine, I will also try without threading based on your comments. (I believed threads were more unstable but not slower). We used 'use Thread;' in earlier version, but I could not find it in the code anymore. Thanks again for some excellent feedback. -- MortenB -----Original Message----- From: Fred Moyer [mailto:f...@redhotpenguin.com] Sent: 12. januar 2010 09:22 To: Morten Bjørnsvik Cc: mod_perl list Subject: Re: unable to compile mod_perl under perl 5.10.1 Here's what's on my 5.8.8 with fPIC, I haven't tried 5.10.1 on 64 bit yet. cc='cc', ccflags ='-fPIC -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm', I'm not sure if the perl you showed me below has fpic configured. I recommend that you compile a non-threaded version of perl though in a separate installation location (with fpic configured of course), and then build mod_perl from that. I usually use /home/app_user/perl. There are a couple of reasons to do this: 1) If you start using CPAN with an rpm based distribution such as centos, then you will be installing modules that should be installed via RPM. The Fedora maintainer gave a note on this in a talk a couple years ago at YAPC Chicago. 2) Single threaded perl binaries tend to be faster (~20%) and more stable than threaded perl binaries. I don't have the data to post, but I did some perlbench comparisons a few years ago with 5.8.8. This may have changed with 5.10, but I would consider it unlikely. 3) You can ensure that you have fpic configured.
