Hi,

building from VS2017, have several projects, for one of projects it just does not want to use cache, checked what may be wrong, there is /c, there is no /Zi, precompiled headers not used, still it always invoke compiler, here is what is logged:

Any idea whatI am doing wrong ?

Also for other projects where it use cache, if I enable /Yu, using of precompiled headers then clcache does not print anything for all file in project, is it invoked at all or ?

Best regards,

I have found more details. Here is what I did, I changed /Z7 to None for that project, I compiled a single file and then I have found in clcache log that it added a result into cache ! After that on each next compilation (even with /Z7) it does use cache ! Other files still are not cached using /Z7. I read /Z7 is file, why it does not add result to cache with /Z7 ? I am using 4.2.0 release installed with pip.

If you are tried to use clcache without tracker support, and then execute clean or rebuild target, your cache can be wiped with build files, as result no cache hits on further builds.

For more details you can see No cache hits when building via Visual Studio IDE or MSBuild
