Eh? It doesn't need to be an absolute path.
To follow up on this for you Ronald, to compile in a PREFIX-safe
relative library path, you need to pass -z origin -rpath
$ORIGIN/../lib/pkgname to the linker... that is a literal $ so assuming
you're using regular make files and gcc as the linker, you would add
this line:
LDFLAGS += -Wl,-z,origin,-rpath,\$$ORIGIN/../lib/$(PORTNAME)
You need to double the $ so that make doesn't expand $ORIGIN for you and
the \ is for the shell. The command line would be something like this:
cc -O2 -pipe -march=pentium4 -Wl,-z,origin,-rpath,\$ORIGIN/../lib/test
test.c -L. -ltest -o test
You may need to fiddle around to get the literal $ in there, a strings
on the compiled binary would include ``$ORIGIN/../lib/test'' (without
the quotes of course).
The reason you *need* to use $ORIGIN is that if you don't the relative
path will be to whatever the pwd is when the process is started making
them effectively random.
Have fun!
