Any suggestions? First of all, what problem are you trying to solve with this? If you need LinuxThreads support, you are out of luck in Fedora Core 5 or newer, there is only NPTL, LinuxThreads has been deprecated for many years. You can set LD_ASSUME_KERNEL even in FC6, but the value needs to be 2.6.9 or higher, but at least for the FC6 shipped libraries it will not change anything. You might try to run the app which you are interested in without LD_ASSUME_KERNEL, if it works with NPTL, fine, if it doesn't, demand a fix from whomever provided it. Jakub
