Hi and hello to everyone on this list,
I ran into the following and I can't figure out what I may do wrong.
Box is FreeBSD 7.3-STABLE Revision: 214445, which is actually of
today, 2010-10-28, on i386.
Buildworld works fine without ccache.
Compiling ports w/ ccache-3.1 works fine, AFAIK until today.
Only default FreeBSD compiler flags are being used for all compilations
further down.
Buildworld with ccache-3.1 though fails on nslexer.o , but it succeeds with
the
previous ccache-2.4.9.
Shown are builds running 'make toolchain' since thats smaller than a
complete
buildworld.
####
-----------------------------------------------------
Builds with ccache-2.4.9 succeed.
Starting with empty ( ccache -Cz ) cache.
ccache-2.4.9 's initial cache after a fresh 'make toolchain':
cache directory
/twelve/.ccache
cache hit 19
cache miss 7911
called for link 173
multiple source files 1
not a C/C++ file 945
no input file 1
files in cache 15822
cache size 57.1
Mbytes
max cache size 976.6 Mbytes:
Everything runs through the build until it is done as it should.
The immediate consequent run of 'make toolchain' succeeds.
ccache -s shows:
cache directory
/twelve/.ccache
cache hit 7947
cache miss 7913
called for link 346
multiple source files 2
not a C/C++ file 1890
no input file 2
files in cache 15826
cache size 57.1
Mbytes
max cache size 976.6 Mbytes
------------------------------------------------------
------------------------------------------------------
####
Same procedure for ccache-3.1, initial cache after a 'make toolchain':
cache directory
/twelve/.ccache
cache hit (direct) 3
cache hit (preprocessed) 16
cache miss 7911
called for link 236
multiple source files 1
unsupported source language 882
unsupported compiler option 213
no input file 1
files in cache 15897
cache size 75.5
Mbytes
max cache size 1.0 Gbytes
Next immediate consequent run of 'make toolchain' (after make clean,
make cleanworld) fails.
ccache -s shows:
cache directory
/twelve/.ccache
cache hit (direct) 1078
cache hit (preprocessed) 46
cache miss 7911
called for link 335
multiple source files 2
unsupported source language 1233
unsupported compiler option 262
no input file 1
files in cache 15905
cache size 75.5
Mbytes
max cache size 1.0 Gbytes

and this is where all related processes stall, waiting forever for things
to happen.
Builds fail with or without different options in the same way as soon as
ccache gets to look for nslexer.o the whole procedure sleeps away.
Thanks for any hints on this issue.
