Subject: tcc should support the -rpath option

Date: Tue, 13 Mar 2012 13:15:38 +0100

[Message part 1 (text/plain, inline)]

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.

I don't understand. How can libtool generate -rpath when even gcc doesn't 
support it? It's a linker option, not a compiler option. Although tcc can link 
files itself, it is not advertised as a linker.

There is support for -Wl,-rpath so the code is clearly implemented. If -rpath 
option does not exist it must be for a good reason.

You can free just after tcc_set_linker as tcc_set_linker does not reuse the 
string.

I'm sorry, I answered too quickly. I forgot to say thank you for the patch.

Regards.

AFAIK, libtool generates the -rpath option, possibly with a linker
prefix. This means in the case of gcc: -Wl,-rpath -Wl,<some_dir>
but tcc doesn't support this (only with the = form).

Oh ok, I see. Then the solution is a bit different. I will definitely look into 
it but with low priority for now, because I'm quite busy.

Best regards.

This will probably also need a change in libtool, but apparently
simpler than introducing another specific format for tcc to the
already bloated libtool.m4 code.

I've reported a wishlist bug against libtool for tcc support, but
there seems to be a problem with the Debian BTS, because after
several hours, it still hasn't appeared.
