Re: Building libobjc2 on ubuntu

[Josh Freeman]

   These instructions worked fine several months back, but failed  
when I tried a couple days ago on a clean, up-to-date 14.04.2 image  
(same CMake errors):
http://lists.gnu.org/archive/html/discuss-gnustep/2014-05/msg00049.html

   However, I was able to get a working build with two tweaks:

1. Use the distro's default clang version (3.4) instead of 3.5 -  
substitute the first line:
sudo apt-get -y install clang git subversion ninja cmake

2. When installing Grand Central Dispatch, the two lines, "sh  
autogen.sh" & "./configure CFLAGS=...", give errors, so substitute a  
plain configure:

./configure


Cheers,

Josh
