the rumours are right, I have built the whole kde suite (emerge kde) |
| 31 |
against uclibc++ (though not all uclibc++ related patches are in kde |
| 32 |
upstream probably - these patches are general c++ failures mostly in kde, |
| 33 |
not uclibc++ specific one, only libstdc++ tolerates some that are not |
| 34 |
allowed by specs). |
| 35 |

I haven't done it your way though. |
| 37 |
I have installed libuClibc++.so into the same dir where libstdc++.so sits, |
| 38 |
I have created an include/uclibcxx for headers at same location as |
| 39 |
include/g++-v3, I have created a new profile in /etc/env.d/gcc that uses |
| 40 |
the same config as the gcc used to build libuClibc++. I have created a new |
| 41 |
dir /usr/arch-*-uclibc/gcc-bin/<gcc-ver>-uclibcxx/ where every app is |
| 42 |
symlinked to /usr/arch-*-uclibc/gcc-bin/<gcc-ver>/, the only change is |
| 43 |
arch-*-linux-uclibc-c++, that is the uClibc++ wrapper |
| 44 |
in /etc/env.d/gcc/ I have copied the config of used build gcc to |
| 45 |
arch-*-linux-uclibc-<gcc-ver>-uclibcxx and replaced |
| 46 |
PATH/ROOTPATH/STDCXX_INCDIR w/ new locations (STDCXX_INCDIR is useless, |
| 47 |
don't rely on that, because it is not used -correctly-, you have to use |
| 48 |
the correct path in the wrapper) |
| 49 |
Now I can switch w/ gcc-config to the profile using uclibc++ as with any |
| 50 |
other gcc one. |
| 51 |
Currently it is heavily dependant on the gcc version used to build |
| 52 |
uClibc++, don't try to use it w/ other gcc. |
