Honors the PATH[1] and other user settings like system wide ccache when selecting hosttools.
Fixes the following compilation error when compiling clang-11: | CMake Error at cmake/modules/CheckCompilerVersion.cmake:38 (message): | Host GCC version must be at least 5.1, your version is 4.8.5. | Call Stack (most recent call first): | cmake/modules/CheckCompilerVersion.cmake:48 (check_compiler_version) on CentOS which by default has the gcc 4.8.5. However, this machine has configured the gcc-7 from Developer Toolset[2] as a default one: $ gcc --version | head -n1 gcc (GCC) 7.3.1 20180303 (Red Hat 7.3.1-5) $ which gcc /opt/rh/devtoolset-7/root/usr/bin/gcc So far, I did not find any other software which would not respect this setup. This will also start honoring system-wide ccache configuration (e.g. widely used on Fedora Linux) where the gcc is used from the non-standard following location: $ which gcc /usr/lib64/ccache/gcc once the user decided to install ccache package: $ rpm -qf /usr/lib64/ccache/gcc ccache-4.2-1.fc33.x86_64 [1] https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_09_01_01 [2] https://www.softwarecollections.org/en/scls/rhscl/devtoolset-7/ Signed-off-by: Damian Wrobel <[email protected]> --- meta/classes/base.bbclass | 6 ------ 1 file changed, 6 deletions(-) diff --git a/meta/classes/base.bbclass b/meta/classes/base.bbclass index b4160402f0..67b0fa1497 100644 --- a/meta/classes/base.bbclass +++ b/meta/classes/base.bbclass @@ -131,12 +131,6 @@ def setup_hosttools_dir(dest, toolsvar, d, fatal=True): if os.path.islink(desttool): os.unlink(desttool) srctool = bb.utils.which(path, tool, executable=True) - # gcc/g++ may link to ccache on some hosts, e.g., - # /usr/local/bin/ccache/gcc -> /usr/bin/ccache, then which(gcc) - # would return /usr/local/bin/ccache/gcc, but what we need is - # /usr/bin/gcc, this code can check and fix that. - if "ccache" in srctool: - srctool = bb.utils.which(path, tool, executable=True, direction=1) if srctool: os.symlink(srctool, desttool) else: -- 2.26.2
