Created attachment 626618 [details] build.log.gz ccache is there in build.log, but: "ccache -s" before build: cache hit (direct) 245674 called for link 70233 called for preprocessing 41451 can't use precompiled header 1118 "ccache -s" after build: cache hit (direct) 245686 (+12) called for link 70252 (+19) called for preprocessing 41454 (+3) can't use precompiled header 1690 (+572) Everything else is the same (I omitted "cache hit rate" and "files in cache"). So the most of ccache calls resulted in "can't use precompiled header".
thanks, I'll check what's going on. probably it uses pch, but not sure yet.
nothing I really can do in the ebuild, upstream uses pch unconditionally. but you can configure ccache to process precompiled headers anyway. refer to https://ccache.dev/manual/3.2.4.html#_precompiled_headers you have to set > sloppiness = pch_defines,time_macros in ccache.conf and add -fpch-preprocess to CFLAGS/CXXFLAGS for telegram. here are results: 1st run --- cache directory /var/cache/ccache primary config /var/cache/ccache/ccache.conf secondary config (readonly) /etc/ccache.conf stats updated Tue Apr 21 00:43:59 2020 cache hit (direct) 1 cache hit (preprocessed) 0 cache miss 101 cache hit rate 0.98 % called for link 19 called for preprocessing 3 can't use precompiled header 572 cleanups performed 0 files in cache 291 cache size 4.6 MB max cache size 120.0 GB 2nd run with default opts --- cache directory /var/cache/ccache primary config /var/cache/ccache/ccache.conf secondary config (readonly) /etc/ccache.conf stats updated Tue Apr 21 00:52:49 2020 cache hit (direct) 100 cache hit (preprocessed) 3 cache miss 101 cache hit rate 50.49 % called for link 38 called for preprocessing 6 can't use precompiled header 1144 cleanups performed 0 files in cache 291 cache size 4.6 MB max cache size 120.0 GB 3rd run with config described above --- cache directory /var/cache/ccache primary config /var/cache/ccache/ccache.conf secondary config (readonly) /etc/ccache.conf stats updated Tue Apr 21 01:14:58 2020 cache hit (direct) 101 cache hit (preprocessed) 3 cache miss 774 cache hit rate 11.85 % called for link 57 called for preprocessing 10 can't use precompiled header 1258 cleanups performed 0 files in cache 2301 cache size 320.9 MB max cache size 120.0 GB 4th run with full cache and options set (compilation is FAST) --- cache directory /var/cache/ccache primary config /var/cache/ccache/ccache.conf secondary config (readonly) /etc/ccache.conf stats updated Tue Apr 21 01:16:26 2020 cache hit (direct) 770 cache hit (preprocessed) 8 cache miss 774 cache hit rate 50.13 % called for link 76 called for preprocessing 13 can't use precompiled header 1258 cleanups performed 0 files in cache 2301 cache size 320.9 MB max cache size 120.0 GB
(In reply to Georgy Yakovlev from comment #5) Thank you for investigation. > you have to set > > > sloppiness = pch_defines,time_macros > > in ccache.conf I'm afraid this can break some other builds... in theory at least. So I'd rather keep it as it is.
closing, as nothing can be done here. I will add a warning to ebuild with a link to this bug, so people can easily discover setup required to make it work.
