It does not for me. My packages were already compiled with gcc-5.4.0. Those |
| 33 |
Buzilla issues only talk about (plasma/qt) packages compiled with previous |
| 34 |
gcc-4.x which are supposed to be incompatible. All of the plasma/qt related |
| 35 |
packages that have been recompiled, because they were built upon |
| 36 |
libQtCore.so.4 were already recompiled with gcc5. I've checked my logs. |
