Problem building when MACOSX_DEPLOYMENT_TARGET set on maxOS about libevent

[azat]

Thanks for the report.

Per #1512, is there any ETA when Libevent 2.2.0

It should be done long time ago... So I don't want to give any ETA .
But basically there is almost zero blockers

Or even a 2.1.13 (even if the only change is being re-bootstrapped with modern versions of the GNU Autotools?)

2.1 is unsupported

[azat]

Also, can you compile from sources (from master branch), will it work?

And verify which minimal autotools version is required, this will really helps.

Also note, that I want to deprecated autotools build system, cmake should be used instead. Can you also give cmake a try?

Fair enough.

What versions are supported?

Compiling on my Mac with all the latest Autotools, both master and the v2.1.12 tarball compile+link fine, with and without the MACOSX_DEPLOYMENT_TARGET environment variable.

$ autoconf --version | head -n 1; automake --version | head -n 1; glibtool --version | head -n 1                               
autoconf (GNU Autoconf) 2.72
automake (GNU automake) 1.16.5
glibtool (GNU libtool) 2.4.7

And verify which minimal autotools version is required, this will really helps.

I can install / try older versions of the Autotools, but that will take a little time. Is there a reason to use something other than the most recent versions?

Also note, that I want to deprecated autotools build system, cmake should be used instead. Can you also give cmake a try?

For what it's worth: cmake would not be preferred for us. Open MPI (and associated projects) are all 100% Autotools.

To close the loop on this already-closed issue -- I haven't been able to find the time to comprehensively test older versions of the Autotools to find the minimal versions that work. I don't know if that matters, though. If there's a reason to use something other than the latest versions (which we know do work properly), let me know and I'll try to find the time.

Thanks for the follow up!

@jsquyres no reasons, this is just to increase compatibility, likely, libevent could be used with lots of old toolchains, but unlikely they need MACOSX_DEPLOYMENT_TARGET, so it is ok to do nothing here :)
