before you tried this command, did you delete the old attempt? eg |
| 34 |
|
| 35 |
crossdev -C arm-softfloat-linux-uclibc |
| 36 |
|
| 37 |
Chances are you have stale uclibc files installed from a previous |
| 38 |
attempt that are conflicting with the current attempt. |
| 39 |
|
| 40 |
Also, make sure you unset PORTAGE_CONFIGROOT, CTARGET, CHOST, and |
| 41 |
CBUILD. Those may foul up crossdev (You're not cross-compiling a |
| 42 |
cross-compiling toolchain are you?). Those variable assignments are for |
| 43 |
_after_ the toolchain is built when you want to use it. |
