6 | # makeedit eclass, will remove -Wreturn-type and -Wall from compiling, this will reduce the RAM requirements. |
| 7 | # To use this eclass, do 2 things: |
|
|
| 8 | # 1. append-flags "$MAKEEDIT_FLAGS". If you filter-flags, make sure to do |
|
|
| 9 | # the append-flags afterward, otherwise you'll lose them. |
|
|
| 10 | # 2. after running configure or econf, call edit_makefiles to remove |
|
|
| 11 | # extraneous CFLAGS from your Makefiles. |
|
|
| 12 | # |
|
|
| 13 | # This combination should reduce the RAM requirements of your build, and maybe |
|
|
| 14 | # even speed it up a bit. |
