[Buildroot] compiling microperl

[Charles Krinke]

I am trying to add microperl to an MPC8321 project and having a
compilation error. I have been using buildroot-2011.03 for the last
year and am nearing the end of this project and today we need to add
perl.

We are using the CodeSourcery external glibc toolchain and it has been
working fine for a long time. This is the first package we are unable
to build.

Here are the errors I am seeing:
make[1]: Entering directory
`/home/ckrinke/asvn/trunk/buildroot-glibc/output/build/perl-5.8.8'

libperl.a(pp.o): In function `Perl_pp_sqrt':
pp.c:(.text+0x8768): undefined reference to `sqrt'

I wonder if someone would be so kind as to offer a clue, or at least a
bread crumb to figuring this out.

See
http://git.buildroot.net/buildroot/commit/package/microperl/microperl.mk?id=cb9a5877b88787f176215c5addb8c1be225a39d0

It lacks -lm in the flags, and this commit fixes it.

Best regards,

Thomas

I'm not sure, but try to
/usr/bin/gcc -L/usr/local/lib -lm  -o miniperl miniperlmain.o opmini.o
libperl.a
I think, the mathlib is missing. My colleague recently had a similar
problem.

your private supporter, Markus ;-)
