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?
Bye,
Alexander.
