1 | # This Makefile snippet defines the following variables: |
| 2 | # | |
| 3 | # CFLAGS: flags for the C compiler | |
| 4 | # CPPFLAGS: flags for the C preprocessor | |
| 5 | # CXXFLAGS: flags for the C++ compiler | |
| 6 | # OBJCFLAGS: flags for the Objective C compiler | |
| 7 | # OBJCXXFLAGS: flags for the Objective C++ compiler | |
| 8 | # GCJFLAGS: flags for the GNU Java compiler | |
| 9 | # FFLAGS: flags for the Fortran 77 compiler | |
| 10 | # FCFLAGS: flags for the Fortran 9x compiler | |
| 11 | # LDFLAGS: flags for the linker | |
| 12 | # | |
| 13 | # You can also export them in the environment by setting | |
| 14 | # DPKG_EXPORT_BUILDFLAGS to a non-empty value. | |
| 15 | # | |
| 16 | # This list is kept in sync with the default set of flags returned | |
| 17 | # by dpkg-buildflags. | |
