If you provide correct paths to ./configure, yes - make && make install will place all the bits in the right places. I commonly use it with DESTDIR and sshfs, so I can develop locally and deploy to a remote machine without building RPMs. > If so, does it have checks for all the runtime dependencies or will you > still have to do a bunch of work afterward the make install? It doesn't check runtime dependencies.

On-PR checks can handle this.

If someone often has this issue, the workflow can be modified to address it.

I think changing the default from "yes" to "autodetect" negatively affects packagers, but it makes it more accessible to upstream developers. -- Tomas Krizek PGP: 4A8B A48C 2AED 933B D495 C509 A1FB A5F7 EF8C 4869
