Dependency error building Qubes

[rucksac...@googlemail.com]

I'm trying to build a Qubes ISO on a Fedora 26 System, following the instructions of the documentation page "Building Qubes OS ISO", and get this error message:

make[1]: Entering directory '/home/xy/qubes-builder'
sudo chroot /home/xy/qubes-builder/chroot-fc25 dnf install -y gcc-6.4.1-1.qubes1.fc25.x86_64 libgcc.x86_64

Error: Unable to find a match.

make[1]: Leaving directory '/home/xy/qubes-builder'
make: *** [Makefile:224: vmm-xen-dom0] Error 1

How can I fix this?

I hit that too but didn't have time to dig in to it. The "qubes1" in the
filename doesn't look quite right, I'd expect just "qubes" but maybe it's
some other issue. If you want to fix it, look at the build-logs and build
script and try to figure out where that is coming from? It's possible it's
already fixed in Marek's repo but hasn't yet made it to master, so you
might want to check recent commits there too.

Found line
RPM_BUILD_DEFINES += --define "qubes_builder 1"
in /qubes-builder/qubes-src/builder-fedora/Makefile.fedora
Should I change it in "qubes builder" or "qubes builder 2"?

[awokd]

No, that doesn't sound right. I think you'd find the filename
"gcc-6.4.1-1.qubes1.fc25.x86_64" somewhere. Maybe file an issue on it, if
there isn't already one out there?

In progress, but it's going to be a few more hours until GCC is done
building to see if it's fixed...

Note my error is slightly different.

Discussion got consolidated to
https://github.com/QubesOS/qubes-issues/issues/3650. Solution looks to be
to revert a commit by hand (or wait until that reversion gets to
qubes-builder/master), then builds should work. Am confirming but builds
take me a long time. Ignore the discussion about "make dist-clean", that
shouldn't be necessary once the fix goes in.
