: You *can* link Linux libraries with FreeBSD binaries (and

Yes.  I have a bunch of printer drivers that I've used that link in
linux shared libraries...  They are in ports...

Good point..
The problem is really the Linux linker - it will find a FreeBSD library and
try and use it ahead of a Linux one later in the search path - this prevents
stuff working :)

I have this exact problem with libfontconfig and Xilinx ISE.

Perhaps instead of ignore, use last.. But then it doesn't really matter for
the FreeBSD linker - I imagine I would have to convince Linux folks it's a
good idea.

Please ignore for a moment that we are not talking about changing the FreeBSD RTLD anymore: Would it make sense (for us and/or for GNU) to first search for libs for the current system and if none are found to try the others?


There is hardly a thing in the world that some man can
not make a little worse and sell a little cheaper.
