I've submitted a patch for libtool:

With gcc, the run path is used with:

  -Wl,-rpath -Wl,/home/vlefevre/software/mpfr/src/.libs

So, I assume that this is only a libtool bug, as libtool should generate
that too (this seems to work when I add that manually).

What the difference between gcc and tcc in this case? Why exe produced
by gcc use ./src/.libs/libmpfr.so and exe produced by tcc use one
installed on the system?

Can you write some small test (library, main program, shell commands)?
If not, I will try to reproduce this some time later.

[Tinycc-devel] shared libraries and run-time path issues

2015-05-21 Thread Vincent Lefevre 
I've reported the following problem for libtool 2.4.6:

  http://debbugs.gnu.org/cgi/bugreport.cgi?bug=20622

but I wonder whether something can be improved on the tcc side
(except by using static linking, which works).

When I build GNU MPFR with CC=tcc LD=tcc and do "make check",
I get things like:

  libtool: link: tcc -O2 -o tzeta_ui tzeta_ui.o  -L../src/.libs 
./.libs/libfrtests.a -lm ../src/.libs/libmpfr.so -lgmp

The problem is that the MPFR library used at run time is not
../src/.libs/libmpfr.so but the one installed on the system.
