Hi Than, I see there is malloc.h present in that path. But, cmake throws one more error even before the mmap issue:
*-- Performing Test SPLIT_STACK_FUNCTIONAL* *-- Performing Test SPLIT_STACK_FUNCTIONAL - Failed* *-- trying -fcf-protection=none workaround* *-- Performing Test SPLIT_STACK_WORKAROUND* *-- Performing Test SPLIT_STACK_WORKAROUND - Failed* *CMake Error at tools/gollvm/cmake/modules/AddGollvm.cmake:68 (message):* * C compiler does not support -fsplit-stack* *Call Stack (most recent call first):* * tools/gollvm/CMakeLists.txt:22 (include)* Tried compiling the compile source specified in cmake file manually with fsplit-stack and workaround of fcf-protection=none. But, linker is unable to find the symbol __morestack: *ld: error: undefined symbol: __morestack* Can you please help if I'm missing out any configuration ? Build environment: clang 13.0.1 on FreeBSD 12.
