Compiling on 32 bit Linux in debug mode
- Eigen will throw an error about some fixed size matrix not being aligned. This is out of our control
- There is a hacky fix, which involves disabling fixed size vector/matrix vectorization.
- Add this to your CMakeLists.txt
# Disable vectorization on 32 bit DEBUG mode. Doesn't work yet. Eigen problem #NOTE : Checks for 32 vs. 64 bit machine. if ( "${CMAKE_SIZEOF_VOID_P}" EQUAL "8" ) SET(CMAKE_CXX_FLAGS_DEBUG "<All your existing cmake debug flags>") elseif( "${CMAKE_SIZEOF_VOID_P}" EQUAL "4" ) SET(CMAKE_CXX_FLAGS_DEBUG "<All your existing cmake debug flags> -DEIGEN_DONT_ALIGN_STATICALLY") endif()
