Linux compatibility: is it possible to link freebsd code t..

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

-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.

From /usr/ports/devel/linux-devtools/pkg-descr

The linux_devtools port contains a selection of packages necessary
for doing development in Linux mode.
