[odb-users] Re: again: bad value ('/dev/null') for '-mtune=' switch

[MM]

Referring to earlier threads on this error, it seems the solution is to

rebuild odb.

Now, I've upgraded from Fedora38 to 39, and that upgraded g++ from

13.2.1 20231011 (Red Hat 13.2.1-4)

to

13.2.1 20231205 (Red Hat 13.2.1-6)

I would have guessed that this would not require a odb rebuild.

Strange

The cc1plus invocation that fails is

cc1plus -quiet -v -mtune=generic -mtune=generic -march=x86-64

-Wunknown-pragmas -Wno-deprecated -std=c++17 -version  -o -.s

This last argument -.s seems incorrecT?


This below which didn't really do anything except relink and reinstall
fixed the problem in this case.

bpkg uninstall odb
$ bpkg build --upgrade --recursive odb
$ bpkg install odb
