Building Perl modules on OpenSolaris

Anyone that’s worked with Perl is probably familiar with is the bundled module that handles downloading and installing modules from the CPAN repository. It usually works flawlessly but I’ve noticed that on OpenSolaris the process can be a bit more spotty.

Let’s try installing Mason as an example:

perl -MCPAN -e "install HTML::Mason"

Generally the first thing I notice is that all (or a large number) of the tests are failing. For example here is the output of one of the tests:

t/20-plugins.......................Can't locate HTML/ in @INC (@INC

 line 14.

Hmm, because we’re not installing HTML::Entities this means that it should have been brought in when was building the dependencies. I trust got this right, if for no other reason than that I remember it prompting to install that module. After digging around in the sea of output eventually I find that installing Digest::SHA1 failed because of this error:

cc -c   -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_TS_ERRNO -xO3 -xspace -xildoff   -DVERSION=\"2.12\" -DXS_VERSION=\"2.12\" -KPIC "-I/usr/perl5/5.8.4/lib/i86pc-solaris-64int/CORE"   SHA1.c
cc: unrecognized option `-KPIC'
cc: language ildoff not recognized
cc: SHA1.c: linker input file unused because linking not done

Our C compiler isn’t happy with how it’s being called. Now we need to find out which compiler we’re using:

 bash-3.2$ which cc

While the GCC compiler is a fine fine compiler, the way tries to build things on OpenSolaris involves params that only SunStudio understands. At this point there are two options. We can either patch the generated Makefile so that it doesn’t include stuff GCC can’t understand or we can switch the compiler to SunStudio. I prefer the latter because it is easiest:

pkg install sunstudio  # Install it if not already done
export PATH="/opt/SUNWspro/bin:$PATH" # Put it first on the path

Now that we’re using the correct compiler the build goes slightly less awful. We get a new error.

/usr/bin/perl "-Iblib/arch" "-Iblib/lib" Build.PL Build
Too early to specify a build action 'Build'.  Do 'Build Build' instead.

This is caused by the ExtUtils::MakeMaker module not being installed. I don’t know how my system got into such a state, but it is easy enough to fix:

perl -MCPAN -e "install 'ExtUtils::MakeMaker' "

Let’s try one more time:

perl -MCPAN -e "install HTML::Mason"
...Huge Snip...
 /usr/gnu/bin/make install  -- OK

  1. You might also try /usr/perl5/bin/perlgcc, which provides alternate compilation settings for use with GCC. So

    # perlgcc -MCPAN -e “install HTML::Mason”

    should just work.
