Is the used gcc surely patched for pie? |
| 21 |
gcc (3.3.3+branch,3.4.0) does not support pie for arm (see my upstream |
| 22 |
pie patches for arm). at least gcc-3.3.3-piepatches-8.7.5, |
| 23 |
gcc-3.4.0-piepatches-8.7.6.1 have to be used. |
| 24 |
check if the startfile/endfile sections mention pie. |
| 25 |

mips could be another problem, because it defaults already to PIC. |
| 27 |
|
| 28 |
could you run gcc -v and send the result for both cases? |
