Not really, that's way too old. Do not expect us to provide fixes for LSB 3. There are people interested in keeping LSB 4 working, though. In the specific case of O_CLOEXEC, I'd recommend this simple fix: #ifndef O_CLOEXEC # define O_CLOEXEC 0 #endif The file descriptor will leak to sub-processes, but you deserve that if you're using a kernel that old. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
