CL kernel preprocess cause compilation error

[handsome-fu]

Test platform:
Odroidn2 with ARM Mali G52, 6.1.22 aarch64 GNU/Linux
Error Log:

Root cause:
clblast enable CL kernel preprocess while it detect ARM gpu(https://github.com/CNugteren/CLBlast/blob/master/src/utilities/compile.cpp#L109), but this perprocessor remove some function definition from original source, so GPU driver will report implicit declaration error.
Please see my attach files, definition of GlobalToLocalCheckedImage has been removed.

Thanks for reporting the issue. I'll see if I can improve the preprocessor. It will take a week or three to find some time for this.

Thanks again for reporting the issue and supplying lots of information to debug the issue. It turns out indeed there is a bug in the pre-processor: it can't handle the !defined(...) construct. I've fixed that now, and extended the test to also cover this situation, see: #498. Perhaps you can already try on that branch?

Note that if you compile the tests, you can also run the preprocessor tests separately like so (e.g. with make on Linux):

make -j4 clblast_test_preprocessor && ./clblast_test_preprocessor
