Bugzilla Bug 19438

I want to build vim on a current Gentoo-1.4 (1.4.2.8) 
In my /etc/profile I use  
 
export WANT_AUTOCONF_2_5=1 
export WANT_AUTOMAKE_1_6=1 
 
for compiling every ebuild with 
autoconf (GNU Autoconf) 2.57 
automake (GNU automake) 1.6.3 
 
When trying to build 
vim-core-6.1-r5.ebuild 
this fails with ./configure hanging at 
checking for /dev/ptc... no 
checking for SVR4 ptys... no 
checking for ptyranges...    [wait forever] 
 
When unseting my default autoconf version and using autoconf-2.13 problems are gone.

please update your automake (1.7.2 is stable

then try again

Its independed from automake. I tried this. Its a autoconf thingy. 
 
 

I can repeat this here (on alpha) with the settings you mention.  Removing
those settings solves the problem.  Sounds like a bug-fix to me! ;-)

I'll look into this a little further, but I don't quite understand the issue
you have.  Using the default settings solves the problem.  Would you explain
why you want those settings?

The problem is that EGREP isn't being set appropriately in configure, so
instead of running "grep -E yes" it's running "yes" which loops infinitely. 
I'll see if I can come up with a solution tomorrow.

I use Gentoo cause its easy to selfcompile things that are not part of the
distribution. 
In my personal experience autoconf-2.5x has the highest compatibility when
building 
my own apps. 

So my /etc/profile ends with: 
export LC_CTYPE=de_DE.utf8 
export WANT_AUTOCONF_2_5=1 
export WANT_AUTOMAKE=1.7 
export KDE_UTF8_FILENAMES=1 

I suggest that an ebuild that needs a definite version of autoxyz-tool forces
this setup 
in the build-script(?) There are more (quite old) programs that have build
problems 
with a modern Gentoo setup e.g. autorun (not part of Gentoo)  or ungif (part of 
Gentoo) 

Thanks for your debugging!

This is fixed in version 6.2_pre6-r1 of vim-core, vim, and gvim.  Bram is also
integrating the patch into his sources.  Let me know how it goes for you.
