Error while writting clcache stats.txt

[9a4gl]

Almost every time I do rebuild whole solution (building from visual studio), it fails and I output I see:

and at the end: 9>Done building project "myproject.vcxproj" -- FAILED.

Is there a workaround for this ?

Using clcache 4.2.0 installed using pip

Try to move clcache dir out of user profile dir (C:\Users\tihomir\clcache -> C:\clcache for example). You can use CLCACHE_DIR environment variable.

Hm, actually I have moved to D:\clcache and I haven't saw this problem anymore. Thanks

I still have this problem with clache being used by gitlab runners. Each runner has its own copy of a clcache dir, but the build process uses cmake with ninja in a multithreaded way.
