No, I did not remember to run 'gcc-config -f 1' because I never knew that it should be done |
| 32 |
and no portage message advised me to do so. `man gcc' or `man gcc-config' also report that |
| 33 |
there is no manual on these packets. Gentoo's Upgrading GCC wiki also says nothing about |
| 34 |
this command... |

| 37 |
|
| 38 |
# gcc-config -l |
| 39 |
* gcc-config: Active gcc profile is invalid! |
| 40 |
|
| 41 |
[1] x86_64-pc-linux-gnu-4.8.3 |
| 42 |
|
| 43 |
Nice! |
| 44 |
|
| 45 |
Ok, trying # gcc-config -f 1 |
| 46 |
* Switching native-compiler to x86_64-pc-linux-gnu-4.8.3 ... |
| 47 |
>>> Regenerating /etc/ld.so.cache... [ ok ] |

| 51 |
|
| 52 |
* . /etc/profile |
| 53 |
|
| 54 |
|
| 55 |
What exactly shall I remember to do? |
| 56 |
|
| 57 |
Ok, # gcc-config -l |
| 58 |
[1] x86_64-pc-linux-gnu-4.8.3 * |
| 59 |
|
| 60 |
Now # emerge --update --deep --with-bdeps=y --newuse --backtrack=90 --ask world |
| 61 |
emerges all three above packages. |
| 62 |
|
| 63 |
Trying to emerge pdftk. Done. |
| 64 |
|
| 65 |
Ok. Thank you. But why there was no hint about it after updating gcc? |
| 66 |
|
| 67 |
Well, there was a reference to Gentoo's Upgrading GCC wiki |
| 68 |
but nothing more... |
