Android build problems #175

Closed marton78 closed 2 years ago

marton78 commented 2 years ago

Hi,

Can you please help me with building for Android? I set the following variables in my CMakeLists.txt:

set(SIMD_TOOLCHAIN   ${ANDROID_CXX_COMPILER})
set(SIMD_AVX512      OFF CACHE BOOL "AVX-512 (AVX-512F, AVX-512CD, AVX-512VL, AVX-512DQ, AVX-512BW) enable")
set(SIMD_AVX512VNNI  OFF CACHE BOOL "AVX-512-VNNI enable")
set(SIMD_TEST        OFF CACHE BOOL "Test framework enable")
set(SIMD_INFO        ON  CACHE BOOL "Print build information")
set(SIMD_PERF        OFF CACHE BOOL "Internal performance statistic" )
set(SIMD_SHARED      OFF CACHE BOOL "Build as SHARED library" )
set(SIMD_GET_VERSION OFF CACHE BOOL "Get Simd Library version")
set(SIMD_SYNET       OFF CACHE BOOL "Synet optimizations enable")
set(SIMD_INT8_DEBUG  OFF CACHE BOOL "Synet INT8 debug enable" )
set(SIMD_HIDE        ON  CACHE BOOL "Hide internal functions of Simd Library" )
add_subdirectory(external/Simd/prj/cmake)

The build process outputs:

What am I doing wrong?

ermig1979 commented 2 years ago

Hi!

Could you try to set SIMD_TARGET="arm".

marton78 commented 2 years ago

I have added

+set(SIMD_TARGET      arm)
set(SIMD_TOOLCHAIN   ${ANDROID_CXX_COMPILER})

but it doesn't make a difference.

ermig1979 commented 2 years ago

Can you give me more information about your platform and used toolchain?

marton78 commented 2 years ago

Sure. I'm on Mac OSX and use Android Studio with NDK. The exact toolchain is written above in the bug.

ermig1979 commented 2 years ago

Unfortunately I haven't got access to MacOS. So I can't reproduce this bug. I check correctness of Simd building for Windows and Linux. I'm sorry but the working of the library on another platforms is not guaranteed.
