Not compiling in Android Studio with gcc for ARM architectures #271

Open dooxe opened 6 years ago

dooxe commented 6 years ago

Hello, When I try to compile g2o for android with gcc for ARM architectures, I have the following error : 

arm-linux-androideabi-gcc: error: unrecognized command line option '-msse2'
arm-linux-androideabi-gcc: error: unrecognized command line option '-msse3'
arm-linux-androideabi-gcc: error: unrecognized command line option '-msse4.1'
arm-linux-androideabi-gcc: error: unrecognized command line option '-msse4.2'

The solution I found to solve the problem is to remove this options like the following in the CMakeLists.txt : Before correction : 

DEFINE_SSE_VAR(SSE2)
DEFINE_SSE_VAR(SSE3)
DEFINE_SSE_VAR(SSE4_1)
DEFINE_SSE_VAR(SSE4_2)
DEFINE_SSE_VAR(SSE4_A)

After correction : 

IF(NOT CMAKE_SYSTEM_PROCESSOR MATCHES "arm")
    DEFINE_SSE_VAR(SSE2)
    DEFINE_SSE_VAR(SSE3)
    DEFINE_SSE_VAR(SSE4_1)
    DEFINE_SSE_VAR(SSE4_2)
    DEFINE_SSE_VAR(SSE4_A)
ENDIF()

I think you should try setting DO_SSE_AUTODETECT to false in your cmake build config.
