You should also apply the following patch:


Otherwise, the build fails with:

/home/thomas/projets/buildroot/output/host/usr/bin/arm-linux-gnueabihf-gcc -l gcc_s -fstack-protector -o miniperl \

pp.c:(.text+0x1fa0): undefined reference to `floor'
pp.c:(.text+0x1fbc): undefined reference to `fmod'
[...]

with certain toolchains.

Also, on the target there is a usr/bin/perl and a usr/bin/perl5.x.y
files. One is a hardlink to the other, but it is always a bit
disturbing to see two big files of the same size. Shouldn't we replace
that by a symlink instead, which is more obvious?

Thanks!

Ok, fixed.

libperl.so  1.2 MB
perl      4 KB (stripped)
perl5.16.1   4 KB
We speak about 4KB !

Here:

$ ls -l output/target/usr/bin/perl*
-rwxr-xr-x 2 thomas thomas 4558484 oct.   4 23:12 output/target/usr/bin/perl
-rwxr-xr-x 2 thomas thomas 4558484 oct.   4 23:12 output/target/usr/bin/perl5.16.1
-rwxr-xr-x 2 thomas thomas   41693 oct.   4 22:59 output/target/usr/bin/perlbug
-rwxr-xr-x 1 thomas thomas     224 oct.   4 22:59 output/target/usr/bin/perldoc
-rwxr-xr-x 1 thomas thomas   10766 oct.   4 22:59 output/target/usr/bin/perlivp
-rwxr-xr-x 2 thomas thomas   41693 oct.   4 22:59 output/target/usr/bin/perlthanks

So it's not exactly 4 KB :)

do you have a shared library libperl.so, in
output/target/usr/lib/perl5/5.16.1/-your-arch-/CORE/libperl.so ?
or in output/build/perl-5.16.1/libperl.so ?

looks like a static linked build
the use of shared lib is forced at configure time by the option : -Duseshrplib

I need to see the ouput of :
on your target :
     # perl -V
or on your host :
     $ output/host/usr/bin/qemu-your-arch output/build/perl-5.16.1/perl -Ilib -V
