2 | Date: 2005-06-14 | |
3 | Initial Package Version: 1.2.2 | |
4 | Origin: Gentoo ebuild? | |
5 | Upstream Status: Not submitted | |
6 | Description: | |
7 | 1. Build shared and static lib in one pass | |
8 | 2. Always add -fPIC when building shared lib, don't expect the user to set it. | |
9 | ||
10 | To build the shared and static library: | |
11 | ./configure --prefix=<prefix> --shared && | |
12 | make && | |
13 | make install | |
14 | Remove the --shared if you don't want the shared lib. | |
