RPM Package

[JtheBAB]

Hi

I try to build it for RHEL systems.

But i get this:

CPack Error: Error when generating package: deconwolf [root@itlegacytest builddir]# less /root/deconwolf-0.4.2/builddir/_CPack_Packages/Linux/RPM/PreinstallOutput.log [root@itlegacytest builddir]# /usr/bin/cmake --build . --target "preinstall" [ 2%] Building C object CMakeFiles/dw.dir/src/deconwolf.c.o In file included from /root/deconwolf-0.4.2/src/method_shb_cl.h:20, from /root/deconwolf-0.4.2/src/dw.h:318, from /root/deconwolf-0.4.2/src/deconwolf.c:21: /root/deconwolf-0.4.2/src/cl_util.h:27:10: fatal error: CL/cl.h: No such file or directory

include <CL/cl.h>

      ^~~~~~~~~

compilation terminated.

According to my search this is due to a missing opencl-headers package. But that package doesn't exists on RHEL systems. Can you build a RPM package? Or tell me how to build it on a RHEL system?

Best wishes

Hello,

I suppose that you have a GPU and want to enable OpenCL acceleration? If not you can pass -DENABLE_GPU=0 to cmake and it will not include the parts that requires cl.h.

It would be strange if opencl-headers (or similarly named) is not available to RHEL. I can see that it exists at least for RHEL8.

I attached a DEB file generated on Ubuntu 24.04 but I am afraid that it isn't portable and that deconwolf has to be built against the correct glibc version. If you let me know what RHEL version that you have I can try to build a deb file for it.

deconwolf-0.4.2-Linux.zip

Cheers, Erik

Also check that OpenCL is installed for the GPU first, clinfo should tell you if it is.

The only opencl that i can find is opencl-filesystem. And it doesn't seam to help.

The system where i build is without a GPU. But Cuda is available. It builds when i disable use the -DENABLE_GPU=0.

But even on a machine with NVIDIA GPU i get:

Then cpack -G RPM

clinfo gives the output of the GPU

Hi again,

I've updated the CMakeLists.txt by adding the line

target_include_directories(dw PRIVATE ${OpenCL_INCLUDE_DIRS})

it was a mistake from my side not to have it from the beginning. On my system it was not needed since OpenCL was installed in a standard directory, i.e.

$ pkg-config OpenCL --cflags

$ pkg-config OpenCL --libs
-lOpenCL

Hopefully the change solves the issues on your machine with the Nvidia card. However, both the shared object libOpenCL.so and the header file(s) cl.h have to exist somewhere on the system.

If it still does not work because of missing CL/cl.h it is possible to copy the CL folder from somewhere else as suggested here.

Let me know if this solves the issue!

Cheers, Erik

Closing this issue since I think that it is solved and there is no activity.
