Linux compatibility: is it possible to link freebsd code to a linux library?

Hello,

Linux compatibility works fine to run linux binaries, but I'm
wondering if it's possible to compile code on FreeBSD and link it to a
linux library?

I want to compile SAP-Rfc, a perl module, to perform RFC to an SAP
server. The code must be linked to librfc.a, a library I can get only
in binary format for linux (no source available).

When I try to compile it I get the following error:
> make
cp lib/SAP/Config.pm blib/lib/SAP/Config.pm
cp Rfc.pm blib/lib/SAP/Rfc.pm
cp Iface.pm blib/lib/SAP/Iface.pm
/usr/local/bin/perl /usr/local/lib/perl5/5.8.5/ExtUtils/xsubpp
-typemap /usr/local/lib/perl5/5.8.5/ExtUtils/typemap Rfc.xs > Rfc.xsc
&& mv Rfc.xsc Rfc.c

-lpthread -L/usr/sap/rfcsdk/lib -lrfc
/usr/libexec/elf/ld: cannot find -ldl
*** Error code 1

I added /compat/linux/lib to the library search path. The library is
found at configuration time, but not at link time.

So my first questions is: Is it possible to compile code on FreeBSD
and link it to a precompiled linux library.

And the second question: If yes, is there something I can do so ld
finds the needed libld and libpthread needed by librfc.a?

Best regards,

Olivier Boudry.
