ccache.bbclass: Set CCACHE_CONFIGPATH to fix race issues
Fixed race issues when parallel build: ccache: error: /path/to/ccache/i586-poky-linux/mmc-utils/ccache.conf: No such file or directory ccache: error: /path/to/ccache/i586-poky-linux/mmc-utils/ccache.conf: No such file or directory This is because we set CCACHE_DIR for earch recipe, and ccache will create a ccache.conf for each CCACHE_DIR when CCACHE_CONFIGPATH is not set, but there might be a race issue in parallel build: ccache gcc file1.c ccache gcc file2.c If the two ccache processes use fopen(path, "w") to create ccache.conf at the same time, the error would happen. Set CCACHE_CONFIGPATH to meta/conf/ccache.conf can fix the problem, and we can add other configs to the file when needed. And also set cache_dir_levels to 1 (default is 2) since each recipe has a cache dir, thus we don't have too many files in one dir. Signed-off-by: Robert Yang <liezhi.yang@windriver.com>
