Kevin answers your direct question. However, based on the other thread, I |
| 13 |
believe your main problem is that you are still using gcc 3.x. Those |
| 14 |
flags I use are for gcc >= 4.1, and *WILL* cause complications on gcc 3.x, |
| 15 |
because 3.x simply doesn't recognize them. As it doesn't recognize them, |
| 16 |
it throws warnings, which causes parts of configure to believe a test |
| 17 |
failed and that something (like the -fPIC flag that must be added for |
| 18 |
libraries on amd64, don't put it in cflags yourself tho) isn't supported, |
| 19 |
so they remove it, causing merges to fail. |
| 20 |
|
| 21 |
IOW, don't try to use my CFLAGS on gcc 3.x! It WILL cause problems! |
| 22 |
Either upgrade (and switch to using gcc-config or eselect compiler) to gcc |
| 23 |
4.1.1, or go back to your regular CFLAGS on gcc 3.x and rebuild to ensure |
| 24 |
you have a clean gcc 3.x system without any contamination from gcc 4.x |
| 25 |
only CFLAGS. |
