Brad Bishop | 1a4b7ee | 2018-12-16 17:11:34 -0800 | [diff] [blame] | 4 | Subject: [PATCH] locale: fix hard-coded reference to gcc -E |
Brad Bishop | d7bf8c1 | 2018-02-25 22:55:05 -0500 | [diff] [blame] | 5 | |
| 6 | When new version of compilers are published, they may not be compatible with |
| 7 | older versions of software. This is particularly common when software is built |
| 8 | with -Werror. |
| 9 | |
| 10 | Autotools provides a way for a user to specify the name of his compiler using a |
| 11 | set of variables ($CC $CXX $CPP etc.). Those variables are used correctly when |
| 12 | compiling glibc but the script used to generate transliterations in the locale/ |
| 13 | subdirectory directly calls the gcc binary to get the output of the |
| 14 | preprocessor instead of using the $CPP variable provided by the build |
| 15 | environment. |
| 16 | |
| 17 | This patch replaces the hard-coded reference to the gcc binary with the proper |
| 18 | environment variable, thus allowing a user to override it. |
