Further to my questions from last week: I've tried both methods - first I tried changing the toolset to make the gcc toolset use "ccache g++" as the compiler executable. I had some problems with that, so I tried the symlink approach suggested by Roland. This is also failing, with some seemingly very subtle bug that I can't suss out. The build progresses a little way, until it gets to libs/program_options/src/cmdline.cpp When g++ isn't a symlink to ccache, I get the following output as shown by the attachment build.log.1.fragment. When I have gcc & g++ symlinks in the ccache bin dir pointing to ccache (the PATH is ccache/bin:real_gcc/bin), the output is like the second attachment and the file fails. The build logs diverge from that point onwards as more and more stuff either fails, or is skipped due to previous failures. There are 2 issues that I can see from those logs. Firstly the line numbering on the .hpp includes is one-out on the ccache-enabled build. Does this mean the preprocessor is behaving strangely? Secondly, on line 15 of the failing fragment file, it looks like part of the output is cut off (at the end of the line, it gets "boost::_bi::list2<boost::_bi::v0.000008 sec system; 0.000164 sec user". Can anyone help me? I don't know what would cause either of these issues.

I'm using Boost on Linux however for various reasons I need to rebuild
parts of it occasionally. For other C/C++-based tools that are built with autoconf/automake, I've started to use ccache (http://ccache.samba.org/) to speed up recompilation. This is done simply by setting the CC / CXX environment variables to "ccache gcc" /
"ccache g++" respectively. I have had a look through the Jam documentation but I can't see an easy way to achieve the same thing when building the Boost distribution. The closest I came was a bit on the trac that simply said I can add a new toolset, but had no real instructions as to how.
Create a file called 'user-config.jam' in your home directory, containing something like: using gcc : : ccache g++ ; Or possibly with the version number: using gcc : 4.4 : ccache g++-4.4 ; For more information see: http://www.boost.org/doc/libs/1_40_0/doc/html/bbv2/advanced.html#bbv2.ad vanced.configuration Daniel _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
