Re: [ccache] How to make ccache not interpret 'multiple'
Hi Joel - what i have been able to figure out is: solaris CC compiler uses
another option(-P) to generate preprocessor file.
If I compile the file with -P and then compile the generated .i file, it works!!
The problem is the -P option doesn't obey the -o option. And ccache
generates that -E output into a special tmp file.
.
Also from a local compiler expert at my company,
As for the errors ... from what I remember, the output of -E is not meant for
recompilation, whereas the output of -P is. That's what I use when I need to
preprocess a source file and submit it to Sun compiler support to demonstrate a
compiler problem with a test case that uses local headers.
-P generates a .i file with same filename as original. So is there anyway to
incorporate this into ccache.c ?
thanks,
Nitin

[ccache] Issues using ccache
I am using first time. I have read documentation but not found my answers. Simple command: ccache gcc -o 1.o 1.c ccache -V ccache version 3.1.4 a) Ran first time and then second time. What called for link means? called for link1 called for link2 It should find it from cache second time. It did not. cache hit (direct) 0 cache miss 0 b) I created a ccache log file(log below is same for exactly same above mentioned gcc command called multiple times). : [2011-01-20T12:01:14.788191 10060] Hostname: sun15 [2011-01-20T12:01:14.788261 10060] Working directory: /home/nkhosla [2011-01-20T12:01:14.788969 10060] No -c option found [2011-01-20T12:01:14.789013 10060] Failed; falling back to running the real comp iler [2011-01-20T12:01:14.789038 10060] Executing /opt/swt/bin/gcc -o 1.o 1.c [2011-01-20T12:01:14.790973 10060] Acquired lock /home/nkhosla/.ccache/a/stats.l ock [2011-01-20T12:01:14.798012 10060] Releasing lock /home/nkhosla/.ccache/a/stats. lock [2011-01-20T12:01:14.798080 10060] Unlink /home/nkhosla/.ccache/a/stats.lock (as -tmp) [2011-01-20T12:01:14.798677 10060] Result: called for link c) Running with solaris compiler (CC) somewhere calls ccfe.

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
