The usual conditional for that is USE=custom-cflags or a similar variant |
| 9 |
like custom-optimization. See the firefox ebuilds, which use both. |
| 10 |
|
| 11 |
$ equery -N u firefox | grep custom |
| 12 |
- - custom-cflags : Build with user-specified CFLAGS (unsupported) |
| 13 |
+ + custom-optimization : Fine-tune custom compiler optimizations (-Os, |
| 14 |
-O0, -O1, -O2, -O3) |
| 15 |
|
| 16 |

Generally, such USE flags are discouraged in gentoo, where honoring a |
| 18 |
user's CFLAGS, etc. and letting them keep the pieces if it comes to that |
| 19 |
is the norm. Where upstream refuses to support custom cflags, however, |
| 20 |
the USE flag solution seems to be an accepted at maintainer discretion. |
| 21 |
|
| 22 |
(FWIW I have USE=custom-cflags set globally, but package.use-disabled it |
| 23 |
for firefox when firefox-28 or so decided it didn't like the ones I was |
| 24 |
using. At some point I'll probably go back and figure out which one it |
| 25 |
is and filter it specifically, but unsetting that USE flag was both a |
| 26 |
useful first-step debug and a reasonable quick fix for the time being.) |
