small number of perl modules that can't be cross-compiled

small number of perl modules that can't be cross-compiled

[Robert P. J. Day]

  after OE recipfying over 100 perl modules from CPAN, i'm down to
less than a dozen that are going to take more work, and a small number
of those seem to be simply badly written in that they don't support
cross-compilation for my target choice of "qemuppc". example
boilerplate recipe i put together produces this:

$ make libauthen-pam-perl
... snip ...
Checking if your kit is complete...
Looks good
checking for gcc... powerpc-wrs-linux-gcc -m32 -mhard-float -mcpu=7400
--sysroot=/home/rpjday/WRL/builds/msm/nov17/bitbake_build/tmp/sysroots/qemuppc
checking for C compiler default output file name... a.out
checking whether the C compiler works... configure: error: cannot run
C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
Error in configuring the Authen::PAM module.
... snip ...

  so i'm assuming the source itself for Authen::PAM:

https://metacpan.org/pod/Authen::PAM

is somehow flawed in that it doesn't properly recognize
cross-compilation, would that be it?

  i'm about to peruse the build process, but if someone has a quick
answer as to what the issue is here, there are 2 or 3 other modules
that have exactly the same issue. much thanks.

It'd be useful to see config.log, ...

... there is at least one issue in Authen-PAM-0.16/configure.ac, I would
say, in that it tries to detect RTLD_GLOBAL support based on the host's
perl. So it's likely there are more flaws.

  that's pretty much all i wanted to confirm at this point -- that it
wasn't something stupid i was doing; rather, the source itself is
flawed, and that's not the only example.

Looks as if Makefile.PL doesn't pass all reasonable flags to ./configure call.
Maybe you should send the Author to http://act.yapc.eu/lpw2016/talk/6966 or
at least send him http://www.netbsd.org/~sno/talks/nrpm/Cross-Compiling-For-Perl-Hackers.pdf :)

That message is referring to config.log from autotools, not the bitbake
do_configure.log. Should be somewhere below ${B}

  sorry, my mistake ... see below:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by Authen::PAM configure 0.16, which was
generated by GNU Autoconf 2.59.  Invocation command line was

  $ ./configure

I think the issues are in your recipe. You should see *many* arguments to

If you meant to cross compile, use `--host'.
