error while loading shared libraries: libtcmalloc.so.0

Bonjour,

Je travaille sur Ubuntu 10.04 x86_64 et eclipse Juno. Dans la configuration d'eclipse (properties -> C/C++ build -> settings), j'ai bien (dans l'ordre) /usr/local/lib et /usr/lib dans la partie "librairy search path". Je code en C.

Quant je lance mon executable, j'obtiens l'erreur suivante:

Code:

error while loading shared libraries: libtcmalloc.so.0: cannot open shared object file: No such file or directory

Et pourtant j'ai bien la librarie dans /usr/local/lib/libtcmalloc.so.0

résultat d'un ldd :
Code:

1 2 3 4 5 6 7 8 9 10 11 linux-vdso.so.1 => (0x00007fff91518000) libtcmalloc.so.0 => not found libprofiler.so.0 => not found libmysqlclient_r.so.16 => /usr/lib/libmysqlclient_r.so.16 (0x00007f256bbd8000) libm.so.6 => /lib/libm.so.6 (0x00007f256b955000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f256b738000) libc.so.6 => /lib/libc.so.6 (0x00007f256b3b4000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x00007f256b17b000) libnsl.so.1 => /lib/libnsl.so.1 (0x00007f256af61000) libz.so.1 => /lib/libz.so.1 (0x00007f256ad49000) /lib64/ld-linux-x86-64.so.2 (0x00007f256bffa000)
Comment se fait-il que la librairie est présente et qu'elle n'est pas trouvée pas le linker ?

Merci d'avance pour votre aide.

J'ai l'impression que le linker cherche dans des endroits bizarre pour trouver le libtcmalloc.so.0 ...

un ldconfig -p | grep "libtcmalloc.so.0" ne trouve rien ...

Le programme tourne quand je fais un:
export LD_LIBRARY_PATH="/usr/local/lib/"

Mais la "vraie" solution je ne la trouve pas ...(sans utiliser LD_LIBRARY_PATH)

Personne n'a aucune idée ?
