Hi @Shipley1105

Could you please share the command used to build the library?

Shipley1105 commented 1 year ago

scons Werror=1 -j8 debug=0 asserts=1 neon=1 opencl=0 embed_kernels=1 os=linux arch=armv7a

Shipley1105 commented 1 year ago

I guess ComputeLibrary is not compatiable with arm-gcc7.3-linux-musleabi, do you have any solution? @morgolock

Hi @Shipley1105

Please take a look at the library's documentation https://arm-software.github.io/ComputeLibrary/latest/how_to_build.xhtml#S1_2_linux

We use gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf to build forarmv7a

To cross-compile the library in debug mode, with Arm® Neon™ only support, for Linux 32bit:

scons Werror=1 -j8 debug=1 neon=1 opencl=0 os=linux arch=armv7a

Hope this helps.
