9978080e WD |
1 | This adds Service Location Protocol support. |
2 | ||
3 | After applying this patch, run these commands for a successful build: | |
4 | ||
27e96866 | 5 | ./prepare-source |
9978080e | 6 | ./configure --enable-slp |
9978080e WD |
7 | make |
8 | ||
6bc8e4ec WD |
9 | TODO: the configure changes should abort if the user requests --enable-slp |
10 | and we can't honor that request. | |
