@tkonolige Looks like libbacktrace build does not look at `CMAKE_CXX_COMPILER` and `CMAKE_C_COMPILER` flags. Regardless of their values it builds libbacktrace for host platform (x86_64) ``` $ cmake .. \ -DCMAKE_C_COMPILER=mips-linux-uclibc-gnu-gcc \ -DCMAKE_CXX_COMPILER=mips-linux-uclibc-gnu-g++ \ -DCMAKE_C_FLAGS="-march=mips32r2 -DDMLC_LOG_STACK_TRACE=0" \ -DCMAKE_CXX_FLAGS="-march=mips32r2 -D_GLIBCXX_USE_C99 -DDMLC_LOG_STACK_TRACE=0" -- The C compiler identification is GNU 5.4.0 -- The CXX compiler identification is GNU 5.4.0 -- Check for working C compiler: /home/alex/workspace/mips-gcc540-glibc222-64bit-r3.3.0/bin/mips-linux-uclibc-gnu-gcc -- Check for working C compiler: /home/alex/workspace/mips-gcc540-glibc222-64bit-r3.3.0/bin/mips-linux-uclibc-gnu-gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /home/alex/workspace/mips-gcc540-glibc222-64bit-r3.3.0/bin/mips-linux-uclibc-gnu-g++ -- Check for working CXX compiler: /home/alex/workspace/mips-gcc540-glibc222-64bit-r3.3.0/bin/mips-linux-uclibc-gnu-g++ -- works ...
