Re: [ccache] Issues using ccache
Ok. Found it. ccache only works with compiler. So -c option has to be there. Tried with solaris compiler. a) CC compiler's one of the options are as -xprefetch=no%auto,explicit . ccache log says: . [2011-01-20T13:45:30.259109 13240] Unsupported language: prefetch=no%auto,explicit [2011-01-20T13:45:30.259199 13240] Failed; falling back to running the real compiler [2011-01-20T13:49:05.281862 3809 ] Result: unsupported source language . I tried ccache PATH/CC --ccache-skip but that did not help. Should not that --ccache-skip ignore interpretation of compiler option? b) Manpage says it may not work with other compiler than gcc/g++. Can anybody confirm that ccache will not work AIX/SunOS compiler suite. thanks, Nitin ___ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache
[ccache] How to make ccache not interpret 'multiple' compiler options
Facing an issue with solaris compiler options. Our solaris compiler command takes many -xflags. Command: ccache CC -xcode=pic32 -xdebugformat=stabs -c -o file.o file.c [2011-01-20T14:54:50.499872 9962 ] Unsupported language: debugformat=stabs [2011-01-20T14:54:50.509438 9962 ] Result: unsupported source language If I remove that flag, it will complain on code=pic32. . I used --ccache-skip but it seems I have to use this BEFORE every flag. So this will work: * ccache /bb/util/common/studio12-v4/SUNWspro/bin/CC --ccache-skip -xcode=pic32 --ccache-skip -xdebugformat=stabs -c -o file.o file.c BUT not this: * ccache /bb/util/common/studio12-v4/SUNWspro/bin/CC --ccache-skip -xcode=pic32 -xdebugformat=stabs -c -o 1.o 1.c . Is there a way to make it work using ccache-skip? Nitin ___ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache

As you have noticed, ccache currently interprets -x flags like GCC does,
which does not work well with compilers that use -x for other things.
There's a bug report about it here:
https://bugzilla.samba.org/show_bug.cgi?id=7556
I used --ccache-skip but it seems I have to use this BEFORE every flag.
Yes, that's correct, and there's currently no other way, unless it's OK
for you to patch your locally built ccache like this:

Re: [ccache] How to make ccache not interpret 'multiple'
Thanks Joel. I made the change and it seems to be working. Though it works even when I do 'not' use --ccache-skip flag at all. a) Is that what you expect? b) It works for simple files But for a heavily templatized source file(object size = 23mb). ccache returned compiler produced no output but object file is generated In cache log [2011-01-20T17:10:13.149794 1100 ] Compiler didn't produce an object file Result: compiler produced no output === Any clues in debugging that? . Goal: I am trying to use ccache to reduce compilation time for heavily templatized code(10 lines of code = 20-30mb of object file and many of such files). I may have to increase default size of 1GB to more. but if there are any other suggestions/limitations to be aware of, please let me know. thanks, Nitin - Original Message - From: Joel Rosdahl j...@rosdahl.net To: ccache@lists.samba.org At: 1/20 16:37:43 On 2011-01-20 21:01, NITIN KHOSLA, BLOOMBERG/ 731 LEXIN wrote: Facing an issue with solaris compiler options. ___ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache ___ ccache mailing list ccache@lists.samba.org https://lists.samba.org/mailman/listinfo/ccache
