[Tinycc-devel] multiple search paths (-Wl,-rpath)

[Vincent Lefevre]

-Wl,-rpath seems to be broken when this option is used several times.

If I configure MPFR with:

  ./configure --prefix=/tmp CC=tcc LD=tcc CFLAGS=-O2

I get things like:

libtool: link: tcc -O2 -o ty1 ty1.o  -L../src/.libs ./.libs/libfrtests.a -lm 
../src/.libs/libmpfr.so -lgmp -Wl,-rpath 
-Wl,/home/vlefevre/software/mpfr/src/.libs -Wl,-rpath -Wl,/tmp/lib

but then I get failures:

$ ./ty1
./ty1: symbol lookup error: ./ty1: undefined symbol: mpfr_free_cache2

$ ldd ty1 | grep mpfr
        libmpfr.so => /usr/lib/x86_64-linux-gnu/libmpfr.so (0x00007f3a575ce000)

while without --prefix=/tmp, everything is fine, as tcc links against
the correct MPFR library:

$ ldd ty1 | grep mpfr
        libmpfr.so => /home/vlefevre/software/mpfr/src/.libs/libmpfr.so 
(0x00007f6f3cc03000)

So, it seems that above, the first -Wl,-rpath is ignored.
