RPI 3A+ VC4C Build error #165

Closed jDietschi closed 1 year ago

jDietschi commented 1 year ago

When building the VC4C Library (running make) it fails while trying to Link CXX shared library libVC4CC.so with the same error as #157

Is this project supported (buildable) on Raspberry Pi 3A+ and if so, how can I install it?

Thanks for this great Projekt and thanks in advance!

collect2: fatal error: ld terminated with signal 9 [Killed]

The linker command seems to have been killed externally. Did you maybe run out of memory?

jDietschi commented 1 year ago

I don't think so I just ran another attempt without the kernel downgrade and got the same Error And is this really compatible for Raspberry Pi 3A+?

VC4CLStdLib and VC4CL build without any erros.

From the last log you posted, it looks like it worked, didn't it?

jDietschi commented 1 year ago

It looks like the building worked correctly. All the output was successfull. running clinfo still gives me the output platforms

Number of platforms                               0`
doe300 commented 1 year ago

To be able to use VC4CL globally, you'll need to configure it with the CMake switch BUILD_ICD=ON, rebuild and reinstall. Then it should be listed (although it requires root rights). Alternatively of course you could LD_PRELOAD the library before any OpenCL-client process invocation.

jDietschi commented 1 year ago

Thanks, I'll try that right away!

Currently running the commands 

mkdir build
cd build
cmake --BUILD_ICD=ON --DMULTI_THREADED=OFF  ..
make
sudo make install
sudo ldconfig

for each directory (VC4CLStdLib, VC4C, VC4CL).

Unfortunately I still get the "Number of platforms: 0" output on clinfo.

the CMakeError.log in VC4C/build/CMakeFiles contains again this output

doe300 commented 1 year ago

The CMakeError.log is irrelevant. This is from an internal CMake capabilities test.

Can you run the clinfo with the OCL_ICD_ENABLE_TRACE=1 and VC4CL_DEBUG=api environment variables?

Also, does the file /etc/OpenCL/vendors/VC4CL.icd exist and what is its content? Should be the path to the VC4CL library.

jDietschi commented 1 year ago

Hi @doe300

After recompiling the whole projekt using the BUILD_ICD=ON switch it seems functional!

Thank you so much for your support. my /etc/OpenCL/vendors/VC4CL.icd file does correctly show the path to the VC4CL library: /usr/local/libVC4CL.so
