hi all I tried to cross compile gcc for arm-elf with pthread support (Eariler i was able to cross compile without thread support using --disable-threads. But now I need the cross compiler with thread.) I tried to configure with --enable-thread but wasn't succesful to build the gcc. The make process gave out an error. --------------------------------------------------- checking for extra compiler flags for building... configure: WARNING: No native atomic operations are provided for this platform. configure: WARNING: They cannot be faked when thread support is disabled. configure: WARNING: Thread-safety of certain classes is not guaranteed. configure: error: No support for this host/target combination. make: *** [configure-target-libstdc++-v3] Error 1 ------------------------------------------------ The error suggests that there is no thread support for arm. If I am right what is the process to add the thread support to arm gcc. And if there is thread support for arm then how should I cross compile to get arm-elf-gcc with thread support. Thanks in advance Regards Vijay Deep
