MacOS fail - AC_INIT should be called with package and version

[edrozenberg]

Since "recently" (weeks) mc no longer builds from source on MacOS when I use the homebrew build formula.
​https://github.com/Homebrew/homebrew-core/blob/master/Formula/midnight-commander.rb

Grateful for any hints.

It seems to have the latest version of autotools installed, and apparently they broke something about AC_INIT. Patches welcome...

Hi,
I can confirm this issue with automake-1.16.4
Since automake-1.16.4 complain predefined empty AC_PACKAGE_VERSION tiggered by following mc configure.ac lines

dnl If AC_PACKAGE_VERSION and AC_PACKAGE_STRING macros are predefined before
dnl AC_INIT call, AC_INIT doesn't redefine them.
dnl As a result, config.h will not contain macros with variable version.
m4_define([AC_PACKAGE_VERSION], [])
m4_define([AC_PACKAGE_STRING], [])

Currently I can not verify why this is needed to keep it out of config.h?

It's needed to get rid of config.h modification after each commit/checkout.
#2252

[and]

Ah,
how about to print (only to stdout) a short mc version string by version.sh to get rid of empty AC_PACKAGE_VERSION/AC_PACKAGE_STRING defines at configure.ac?

[edrozenberg]

Thanks for the patch, tried and it didn't fix the issue on MacOS, assuming my brew formula edit did the right thing

This patch prepared only a possiblity to remove automake-1.16.4 problematic lines from configure.ac without having a regression for #2252

dnl If AC_PACKAGE_VERSION and AC_PACKAGE_STRING macros are predefined before
dnl AC_INIT call, AC_INIT doesn't redefine them.
dnl As a result, config.h will not contain macros with variable version.
m4_define([AC_PACKAGE_VERSION], [])
m4_define([AC_PACKAGE_STRING], [])

You need to remove these lines from configure.ac to fix automake-1.16.4 issue

Thanks a lot - worked great on MacOS to build cbc214da8 (Midnight Commander 4.8.26-232-gcbc214da8) after applying the mc-* patch from earlier + the patch below based on suggested line removals.
