Trying to compile imagemagick with opencl
After the config step I see opencl enabled:

However the final binary does not list OpenCL in it feature

I am using AMD Ryzen 9 5900HS with Radeon Graphics (16)
I have opencl-mesa opencl-headers & ocl-icd installed, with amdgpu driver loaded

Steps to Reproduce

./configure --enable-opencl <- Detects OpenCL and adds it to the features
make
sudo make install

convert -version < -- Fails to show opencl in the feature list

Your config.log may explain the problem.

Okay I see this:

Is it trying to fetch the supported OPenCL version from NVIDIA libs?

clinfo gives the following output:

IM should be using OCL version 1.1 in that case?
The log suggests it is trying to use version 3.0.0 . I tried exporting CL_TARGET_OPENCL_VERSION=110 with no luck.

[snibgo]

Sorry, I don't know enough about OpenCL. It looks as if your OpenCL source code is 3.0.0 but the installed version is 1.1. Such a large difference in version numbers suggests they may not be compatible.

Did you do automake and autoconf?

Is that the only reference in config.log to OpenCL? It looks more like a warning than an error that would prevent a build with OpenCL.

[DroidFreak32]

Yes these are the only noteworthy reference to opencl.

I did compiled following https://imagemagick.org/script/install-source.php
I did not do automake or autoconf.

Is Imagemagick incompatible with OCL 1.1?

[dlemstra]

Can you give this another try with the latest release?

Ping @DroidFreak32

[DroidFreak32]

Sorry for the delay in response @dlemstra , I will test it today and edit this comment with my result.

EDIT:
Works now! Thanks @dlemstra
