| 7 | # AX_COMPILER_FLAGS_GIR([VARIABLE], [IS-RELEASE], [EXTRA-BASE-FLAGS], [EXTRA-YES-FLAGS]) |
| 8 | # |
| 9 | # DESCRIPTION |
| 10 | # |
| 11 | # Add warning flags for the g-ir-scanner (from GObject Introspection) to |
| 12 | # VARIABLE, which defaults to WARN_SCANNERFLAGS. VARIABLE is AC_SUBST-ed |
| 13 | # by this macro, but must be manually added to the SCANNERFLAGS variable |
| 14 | # for each GIR target in the code base. |
| 15 | # |
| 16 | # This macro depends on the environment set up by AX_COMPILER_FLAGS. |
| 17 | # Specifically, it uses the value of $ax_enable_compile_warnings to decide |
| 18 | # which flags to enable. |
