* gnu/packages/build-tools.scm (tup): Update to 0.7.11.
[phases]<configure,build>: Force it to use fuse instead of fuse3
---

There is probably a cleaner way to do that format thingy.  I just can't be asked to figure that out right now, sorry.  This package gave me to much grief to go the extra mile :P


Wanted to play with this as it seems cool but I kept getting this error when running it:

> setpgid: Operation not permitted
> tup error: Unable to set process group for tup's subprocesses.

So then I updated it to 0.7.11 (changed fuse to fuse-3), built it just fine, and got this error instead when running it:

> fuse: failed to exec fusermount3: No such file or directory

I tried pretty hard to fix it but I couldn't figure it out.  It's pretty darn cryptic.  I can't figure out where it's trying to call it from.  So I just built it with fuse instead of fuse3 and now everything works great.  No errors at all.

Well it has been a year so I thought I'd come back to this.  I figured
it out.  It needs to run fusermount from /run/setuid-programs because it
needs those permissions I guess.  So running this program depends on the
user's system configuration which I don't think is a good thing (and
probably translates badly on foreign distros.)

If I could get someone more knowledgeable then me to weigh in here that
would be great because I have no clue how to proceed.

If I install fuse-3 alongside tup built with fuse-3 then I get the
following error.  If fuse-3 is installed as a setuid program it works
perfectly.  The only reason everything currently works is because we
install fuse by default as a setuid program.

> fusermount3: mount failed: Operation not permitted
