Hello First of all, sorry about the typo in the subject/title of my post. I run ccache in read-only mode itself. But, I still see that after the direct cache lookup fail, it falls back to running the preprocessor. That's exactly what I wanted to avoid.
It seems to me that having an option to avoid preprocessing after a direct-cache-lookup fail is still a very valid option if the user knows that preprocesor will result in a failure/he purposefully wants to avoid it. I hope my justification is valid. 88 [2014-09-05T14:45:17.445383 25208] Hostname: host.myhost.net 89 [2014-09-05T14:45:17.445393 25208] Working directory: (null) 90 [2014-09-05T14:45:17.445399 25208] Base directory: /var/fpwork/workspace_venkrao/release 91 [2014-09-05T14:45:17.445734 25208] Source file: ../my_source.cpp 92 [2014-09-05T14:45:17.445745 25208] Dependency file: ../my_source.d 93 [2014-09-05T14:45:17.445752 25208] Object file: ../my_source.cpp.o 94 [2014-09-05T14:45:17.447011 25208] Trying direct lookup 95 [2014-09-05T14:45:17.447167 25208] Looking for object file hash in /disk1/ccache_cache_store/transport_release/175750/0/5/eb2b36e5e9d0bb723de833a4529cab-11859.manifest 96 [2014-09-05T14:45:17.479757 25204] Looking for object file hash in /disk1/ccache_cache_store/transport_release/175750/6/6/e186baaf3c2e9e06619878dac77fe1-114310.manifest 97 [2014-09-05T14:45:17.863524 25194] Did not find object file hash in manifest 98 [2014-09-05T14:45:17.864854 25194] Running preprocessor Regards, venkrao On Fri, Sep 5, 2014 at 1:51 AM, Andrew Stubbs <a...@codesourcery.com> wrote: > On 04/09/14 08:32, vkr wrote:> I would like to know if I can avoid >> "If there is no match, ccache falls back to running the preprocessor." > > The answer is "no", because it is necessary to run the preprocessor in order > to fill the cache and record the file list that direct mode lookups use. > > It might be possible if you wanted to run the cache in read-only mode, but > that might not be very useful, and I don't believe there's an option for > that now. > > Andrew _______________________________________________ ccache mailing list firstname.lastname@example.org https://lists.samba.org/mailman/listinfo/ccache
