Hello, You don’t need to rebuild if you can be sure that all files have been replaced/changed. I am always trying to rather safe than sorry, so I rather do an extra build instead of breaking the build for somebody else. This doesn’t always work, but I will try. If I change a CGI file, I copy it manually to the right place, or if there are multiple I figure out which lfs-file is responsible and delete the corresponding log file before I run “./make.sh build” again. Then I will have an ISO with the right content. Does this answer your question? -Michael > On 9 Aug 2021, at 14:42, Adolf Belka wrote: > > Hi All, > > > When I am doing changes to programs and addons then it is clear that I need to do full make.sh clean and make.sh build before doing any commit. > > > If I am changing language files then I know that I need to run make.sh lang but do I also need to run make.sh clean and make.sh build before the make.sh lang and if I am looking to submit a patch for a .cgi file do I also need to run make.sh clean and make.sh build before doing the git commit on the changed cgi file? > > > Thanks, > > Adolf >
