Hi, it would be nice if uclinux targets are allowed to enable posix threads. Together with uClibc-ng/uClibc you can build m68k-nommu toolchain and enable old Linuxthreads instead of NPTL/TLS. With following change it is possible to build boost, which checks if gcc is build with threads enabled. Tested with a simple boost application on qemu-system-m68k emulating a coldfire board without MMU. Other noMMU targets as cortex-m3/cortex-m4 will benefit from this change, too. The patch is used in Buildroot for a while without causing issues. 2016-12-02 Waldemar Brodkorb <wbx@openadk.org> gcc/ * gcc/config.gcc: Enable posix threads.
