Leela-zero-next doesn't compile on old CPU (without OpenCL). What about to make binary releases?

Is it possible to make binary releases like KataGo (https://github.com/lightvector/KataGo/releases/latest)?

In this case it will be the really inducement to download new version, especially considering that there isn't any game level strengthening compared with last release (https://lifein19x19.com/viewtopic.php?f=18&t=13322&p=269439#p269439).

Did you update the submodules?

[GD-fix]

When? Last commit is still from Aug 24, 2021...

[GD-fix]

In 06.02.23 version all the same...

Leela Zero isn't currently being maintained. But your problem seems to be related to library installation (of Qt5), it is not specific to Leela Zero.

[GD-fix]

Last commit of the LeelaZero "next" branch: "on Feb 6"...

The OS (OpenSUSE Tumbleweed) was completely updated before last LeelaZero "next" branch version compiling, but the problem remains:

add_subdirectory(gtest EXCLUDE_FROM_ALL) # We don't want to install gtest, exclude it from all
After deletion of this string it was compiled (but with error in dependencies of target tests) and run...

So the problem seems to be related to LeelaZero "gtest" module...

[GD-fix]

This version of non "being maintained" LeelaZero is stronger than official release...

[OmnipotentEntity]

Last commit of the LeelaZero "next" branch: "on Feb 6"...

That was a link correction. So was the previous commit. The last actual code change was on May 4, 2021 slightly more than 2 years ago at this point. Meaning that the measurement that LeelaZero has somehow gotten stronger is quite simply wrong, and the observed changes are merely an illustration of statistical noise.

Anyway, your error your originally posted about is because you do not have the development libraries for OpenCL and Qt5 installed on your computer, or that they are not in the location that CMake is searching for them in. If the former, simply install the libraries. If the latter tell CMake where to find the files manually. For this using an interactive cmake command such as ccmake might be beneficial.

However, if you have the previously compiled version of the code released in May 2021, then you do not need to recompile the code because absolutely nothing has changed since then.

Hope this helps.

How developers said, there is not any reason to use GPU with my video card. So, I'm using (see the title and the beginning of this issue):cmake -D USE_CPU_ONLY=1
Why in this case should it matter if I have OpenCL libraries or not at all?

Thanks in advance.

P. S. I have both previously and last compiled versions, because there isn't the problem with QT5 on new OS and:

After deletion of the string:
add_subdirectory(gtest EXCLUDE_FROM_ALL) # We don't want to install gtest, exclude it from all
it was compiled (but with error in dependencies of target tests) and run...

The goal of this issue is to ask developers to upload compiled releases (individual for GPU and CPU only support like KataGo, or only one, but with something like --nogpu run for CPU only support)...
