dev-util/ccache: add USE=static-c++ which embeds libstdc++ |
9 |
|
10 |
To ease building gcc with ccache we need to handle the case of |
11 |
LD_PRELOAD=./inplace/libstdc++.so injected by gcc's build system. |
12 |
|
13 |
USE=static-c++ uses -static-libstdc++ for it. |

ccache acts as a caching pre-processor to C/C++ compilers, improving |

compilation time when recompiling previously compiled source. |
