Created attachment 735961 [details, diff] Patch to remove obsolete Regex.cc and Regex.h Currently, snapper is not working with musl libc due to the files Regex.cc and its header Regex.h, which are signed as obsolete in the source code and will be removed on future releases. So I've written a patch to remove those files and fix the problem for the current version. It shouldn't be a problem to remove those files as they were left to keep binary compatibility, which shouldn't be a problem on Gentoo.
