Thank you Micha, I wasn't aware of that. It appears that the generic tool behind linux32 is "setarch" Here is a link for reference: http://linux.die.net/man/8/linux32 http://linux.die.net/man/8/setarch I never tried it with cmake for building 32 vs 64 binaries on 64 bits system, I'll try it. -- Erk Le gouvernement représentatif n'est pas la démocratie -- http://www.le-message.org -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
