The problem is that there are many versions of libtest
(lib/libtest-2.so, lib/libtest-3.so), and I want to select the library
by adding a -L linker flag to the corresponding directory, without
altering the program (each lib/test2, lib/test3, etc. has a symlink
libtest.so which points to the corresponding one; I want the mapping to
take effect at link time).
For example (note that I didn't specify -ldb-4.2, just -ldb, and
lib/db42 isn't in the linker path):
% cc test.c -L/usr/local/lib/db42 -ldb
% ldd a.out
a.out:
libdb-4.2.so.2 => /usr/local/lib/libdb-4.2.so.2 (0x28077000)
libc.so.6 => /lib/libc.so.6 (0x2814a000)
When I try it after symlinking the lua4 library this happens:
% cc test.c -L/usr/local/lib/lua4 -llua
% ldd a.out
a.out:
liblua.so => (not found)
libc.so.6 => /lib/libc.so.6 (0x2814a000)
I would like to achieve the same result as the first case.
Thanks and Best Regards,
Ale
