With Microblaze Gcc version < 8.x build hangs on compiling first files. This is due to bug 71124: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71124 This package has been excluded from building if BR2_microblaze is enabled. Bug shows up building assimp with optimization but not when building with -O0. In config.mk if BR2_TOOLCHAIN_HAS_GCC_BUG_71124=y force using -O0 by: - passing -O0 to ASSIMP_CXXFLAGS Then remove 'depends on !BR2_microblaze' and its comment if not available from Config.in Signed-off-by: Giulio Benetti <giulio.benetti@micronovasrl.com> --- package/assimp/Config.in | 5 ----- package/assimp/assimp.mk | 4 ++++ 2 files changed, 4 insertions(+), 5 deletions(-)
