It seems that the repository for libevhtp is gone. Would it be possible to update your repository to a more recent version?
By the way, in the manual why are you turning off SSL ?
We still use an old version of libevhtp since the new version may be unstable. The SSL support also seems to be buggy so we don't use it. And it's unnecessary since you can use Nginx/Apache in front of Seafile server.
Ok thanks for the answer, I'll drop this old dependency
After some tests it seems impossible to build seafile-server without libevhtp, is there any hidden option to disable it?
