Package: tcc
Version: 0.9.26~git20120104.83d57c0-4
Severity: wishlist
Tags: upstream patch
tcc should support the -rpath option, as it is generated by libtool
(e.g. to be able to build the MPFR tests with shared libraries
enabled). The attached patch does that (please review it, as I am
not familiar with the tcc code).
The patch itself seems to work on my x86_64 machine (though running
the test is another problem...). At least its behavior is equivalent
to -Wl,-rpath.
Note that it does not free the memory explicitly when the program
ends. I don't think this is a problem in practice, except when
testing with tools like valgrind.
