You're right, it's not about the whitespace. What I think is happening is that 'ccache' is set up as a set of symlinks with the same names as the compilers: $ ln -s $(which ccache) gcc $ ./gcc -v Using built-in specs. <...> gcc version 12.2.0 (Debian 12.2.0-14+deb12u1) This should be mostly transparent - ccache reads the name of the symlink from argv[0] and does the right thing - except configure.R uses normalizePath(), which expands the symlink: $ Rscript -e 'normalizePath("./gcc")' [1] "/usr/bin/ccache" https://github.com/tylermorganwall/libdeflate/blob/37823652cde424bcbba6916875620985be7c8837/tools/config/configure.R#L73-L78 Since CMake runs from the same shell as configure.R and so should have the same PATH, it should be safe to tell CMake only the name of the compiler, without Sys.which() or normalizePath(). -- Best regards, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
