Build Error

[ixiDev]

Hi there.
I try to build this package on Raspberry Pi3B with ubuntu rasp 22.04 LTS
and I get this error

VC4C/src/llvm/BitcodeReader.cpp:1045:39: error: ‘const class llvm::CallInst’ has no member named ‘getNumArgOperands’; did you mean ‘getNumOperands’?
 1045 |         for(unsigned i = 0; i < call->getNumArgOperands(); ++i)

I change getNumArgOperands to getNumOperands and the compilation success but after I install all packages (VC4C,VC4CL) and run clinfo here is the output

pi@rpi3:~/Downloads/VC4CL$ clinfo

What do you mean with "ubuntu rasp 22.04 LTS"? Are you using Raspberry Pi OS or an Ubuntu? In any case, VC4CL does not work anymore with the "new" Raspberry Pi OS and any other OS might not have the required firmware runtime libraries installed at all.

Thanks for reply <3

I test it right now on the latest Rasbian and it's not working, its compile but I get the same error

is there anything to do or just go back to old Raspbien ? thanks again

You will need to provide a more detailed stack trace for me to find out the reason for the crash. Can you for example run the code with GDB and then post the stack trace on crash?

Something like:

gdb clinfo
(in gdb shell) run
(in gdb shell when the SEGFAULT is caught) bt

[ixiDev]

Her is the stack trace from gdb

Reading symbols from clinfo...

(gdb) 

I think the error comes from the prebuild libOpenCL.so that comes with the latest Rasbian OS because when I build VC4CL it linked I guess with /lib/arm-linux-gnueabihf/libOpenCL.so but here is ldd for libVC4CL.so

CMake Deprecation Warning at CMakeLists.txt:4 (cmake_policy):
  The OLD behavior for policy CMP0026 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.
