[gentoo-embedded] perl / -lgcc_s

[gentoo-embedded] perl / -lgcc_s

[Corey]

Ok, well - after much effort, it looks like I'm just not going to be successful
cross compiling perl.

So I decided on a new strategy:  I'd compile perl manually while chroot'd
into my minimal uclibc-based gentoo partition. However, things go fine
until the make process dies with the following:

"/usr/lib/gcc/i686-pc-linux-uclibc/4.1.1/../../../../i686-pc-linux-uclibc/bin/ld: cannot find -lgcc_s"

Well, this is highly annoying, because I do in fact have libgcc_s.so.1:

scanner lib # pwd
/usr/i686-pc-linux-uclibc/lib
scanner lib # ls -l libgcc_s*
-rwxr-xr-x 1 root root 34980 Nov 20 03:51 libgcc_s.so
-rwxr-xr-x 1 root root 34980 Nov 20 03:51 libgcc_s.so.1
scanner lib # readelf -d libgcc_s.so.1

Dynamic section at offset 0x7834 contains 21 entries:
  Tag        Type                         Name/Value
 0x00000001 (NEEDED)                     Shared library: [libc.so.0]
 0x0000000e (SONAME)                     Library soname: [libgcc_s.so.1]


I even went and copied thos libgcc_s.so* into every lib directory
I could think of, but it keeps complaining nonetheless. I'm really
stumped here - why is it saying it can't find it?


Thanks

There are some gotchas with cross-compiling Perl, but there is something 
called "microperl" which is small enough to cross-compile.
