This is particularly common when software is built with -Werror. Autotools provides a way for a user to specify the name of his compiler using a set of variables ($CC $CXX $CPP etc.). Those variables are used correctly when compiling glibc but the script used to generate transliterations in the locale/ subdirectory directly calls the gcc binary to get the output of the preprocessor instead of using the $CPP variable provided by the build environment. This patch replaces the hard-coded reference to the gcc binary with the proper environment variable, thus allowing a user to override it. --- locale/gen-translit.pl | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/locale/gen-translit.pl b/locale/gen-translit.pl index 30d3f2f..7b287fa 100644 --- a/locale/gen-translit.pl +++ b/locale/gen-translit.pl @@ -1,5 +1,5 @@ #!/usr/bin/perl -w -open F, "cat C-translit.h.in | gcc -E - |" || die "Cannot preprocess input file"; +open F, 'cat C-translit.h.in | ${CPP:-gcc -E} - |' || die "Cannot preprocess input file"; sub cstrlen {
