why clEnqueueReadImage is not linkable in the built lib.

[lyz9801]

Dear , I built a program with arm_compute-v22.05-bin-android-arm64-v8a-cl\lib\arm64-v8a-cl\libarm_compute.so , it got an error as below: undefined reference to `clEnqueueReadImage' clang++.exe: error: linker command failed with exit code 1

other cl apis has no problem , like clCreateImage.

is the function clEnqueueReadImage forbidden in the arm system? it is ok in windows X86 .

Hi @lyz9801

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

Please see the documenation on how to build the examples: https://arm-software.github.io/ComputeLibrary/latest/how_to_build.xhtml#S1_2_2_examples

Hope this helps

Hi, @morgolock

I havn't built the program yet, just directly use the library in the hompage , the linked address is https://github.com/ARM-software/ComputeLibrary/releases/download/v22.05/arm_compute-v22.05-bin-android-arm64-v8a-cl.tar.gz

in ComputeLibrary-main/src/core/CL/OpenCL.cpp, there is an implementation of clCreateImage, but I cannot find clEnqueueReadImage , which is also a standard api in https://www.khronos.org/files/opencl30-reference-guide.pdf . I‘m not sure whether this api is supported in the embedded computing system. As in the intel X86 platform, the api can be found in https://gitlab.freedesktop.org/beignet/beignet/-/blob/master/src/cl_api_mem.c

Could you please elaborate and explain how do you use the library?

What device and OS are you using?
