ccache

Trying to combine ccache and colorgcc. Following link text : my g++ is soft link to colorgcc ~/.colorgccrc contains line: "g++: ccache /usr/bin/g++" When running g++ --version receive: Can't exec "ccache /usr/bin/gcc": No such file or directory at /usr/lib/perl5/5.8.8/IPC/Open3.pm line 246. open3: exec of ccache /usr/bin/gcc --version failed at /usr/local/bin/colorgcc/gcc line 208 Any ideas how to solve it? Just came across this same issue. For me, the problem could be solved by carefully setting environment variables: # Make "g++" command call colorgcc export PATH="/usr/lib/colorgcc/bin:$PATH

I am aware that scons implements the functionality of ccache , but I am stuck with another build system. I also know there is a gocache project on SourceForge that aims to implement ccache -like functionality for other compilers, but it seems not complete. A shameless plug, but I wrote a Python script which attempts to work just like ccache, except that it can wrap MSVC. See https://github.com/frerich/clcache Chris Dolan There's an unofficial patch to ccache to support MSVC , but I haven't yet tried it myself... js.mouret Stashed It supports PDB, PCH, and has a nice dashboard. Disclaimer: I'm

I use CMake to create a makefiles. CMake creates GCC line containing absolute paths. To speed up compilation I use ccache. Building same code from different locations (e.g. several developers compile the same code, each under its home directory) causes ccache cache misses. As mentioned in a comment above, one problem is that any absolute paths in the preprocessor line directives are hashed by ccache, and if the compiler option -g is used, the compiler emits an absolute path to the source code file as well. Another similar problem is that if the path to the source code file is absolute on the

I would like to do the following: If CCache is present in PATH, use "ccache g++" for compilation, else use g++. I tried writing a small my-cmake script containing CC="ccache gcc" CXX="ccache g++" cmake $* but it does not seem to work (running make still does not use ccache; I checked this using CMAKE_VERBOSE_MAKEFILE on). Update: As per this link I tried changing my script to cmake -D CMAKE_CXX_COMPILER="ccache" -D CMAKE_CXX_COMPILER_ARG1="g++" -D CMAKE_C_COMPILER="ccache" -D CMAKE_C_COMPILER_ARG1="gcc" $* but cmake bails out complaining that a test failed on using the compiler ccache (which
