unrecognized command line option '-mavx' #5

Closed Jister closed 7 years ago

Jister commented 7 years ago

Hi, when I compile the code on NAVIDIA Jetson TK1, it shows c++: error: unrecognized command line option '-mavx'

how can I solve it?

adujardin commented 7 years ago

Hi, For the Jetson, remove -mavx from the CMakeLists.txt (here)

I remove it from CMakelist.txt, it still shows me the same error. Now the CMakelist is as the following shows: ... link_directories("/usr/lib/aarch64-linux-gnu/tegra") ## on Jetson TX1 64bits, the correct libGL.so is located here (the default one will lead to linking error (undef ref)) endif()

add_definitions(-Wno-write-strings)
SET(LINUX_LIBRARIES "pthread" "X11")

ENDIF(WIN32) ...

You should clean the cache and re-run cmake in that case, in the sample folder : 

    cd build
    rm -rf *
    cmake ..
    make

I have clean it, and even remove the build file and re-create it, still the same error, it's really confusing.

Ok, Could you open the file /usr/local/zed/zed-config.cmake and check if you have an "AVX Check" that add the definition ? If so remove it and test again.

It seems that cpuid believe that the CPU has AVX support somehow (from the log "build with AVX support... detected from cpuid")

Jister commented 7 years ago

Yes, I remove it and it can compile now, thank you very much for your help.
