To be removed after we merge stdenv-updates in.
|
|
||||||
stdenv-updates should have this gcc-wrapper2 as gcc-wrapper.
|
|
||||||
|
|
||||||
Changelog against gcc-wrapper:
|
|
||||||
- Support for linking shared objects with direct mention of the /path/libxxx.so object,
|
|
||||||
thus, adding its path to the rpath.
