Hi, I have recently been trying to update my fork of the
magicseteditor project, which can be found here:
https://github.com/cooljeanius/magicseteditor
At first, autoconf told me:
configure.ac:109: warning: AX_CXX_COMPILE_STDCXX_0X is obsolete; use
AX_CXX_COMPILE_STDCXX_11 instead
...so I followed its recommendation and updated
AX_CXX_COMPILE_STDCXX_0X to AX_CXX_COMPILE_STDCXX_11, and
AX_CXX_HEADER_STDCXX_0X to AX_CXX_HEADER_STDCXX_11, and once I had
done that, it failed with this message instead:
$ autoreconf -fvi -Wall
autoreconf: export WARNINGS=all

Since it said to report this here, that is what I am doing. I am using
automake 1.16.3 as installed by MacPorts. Any idea what's going on?
Thanks,
Eric Gallager

Ei Eric,

        Automake::ChannelDefs::prog_error("too many loops") called at
    /opt/local/bin/aclocal line 1187

I've never seen that error before. The comment in aclocal where the
check is done says:

# We may have to rerun aclocal if some file have been installed, but
# it should not happen more than once. 

So, hmm.

    https://github.com/cooljeanius/magicseteditor
    ...
    automake 1.16.3 as installed by MacPorts. Any idea what's going on?

Nothing springs to mind, sorry.

Is it reproducible? Any chance you can cut down your configure.ac and
project to something smaller? Else I guess I can try taking your project
and making the same change (eventually).

Thanks for the report. --karl

Nope, I can't seem to reproduce it, unfortunately; after trying again
more recently, it started working again, and I'm not sure what might
have changed in my environment to cause that to happen... sorry, this
can be closed...

    more recently, it started working again ...

Not sure if that's good or bad, but at least you can get on with life :).
Thanks for checking back.

    this can be closed...

Closing. --thanks, karl.
