Pakl: /* Compiling manually */

The most simple way to get an up-to-date installation of GNUstep on Debian or Ubuntu is to add the [https://launchpad.net/~gnustep-dev/+archive/weekly GNUstep weekly PPA] to your distribution sources, provided by the GNUstep Developers team on Launchpad. On how to do this in detail, see the PPA page.

== Compiling manually ==

* Uses clang and libobjc2 for all the new features like ARC, Blocks, etc.
* Works with a fresh install and likely with a more completed installation.
* Works on Ubuntu 12.10 Server.
* Works on Ubuntu 13.10 Desktop.
* If you're trying Ubuntu 12.04 Desktop, see bottom of the page for help.

After this, you can try to install EtoileOS: see [[EtoileOS under Ubuntu Linux]].

Ubuntu 12.04 Help

In Ubuntu 12.04 Desktop, the installed version of CMake is 2.8.7 but you need 2.8.8 or later to compile LLVM.

<pre>
patryk@telperion:~/llvm/build$ cmake ..
CMake Error at CMakeLists.txt:3 (cmake_minimum_required):
CMake 2.8.8 or higher is required. You are running version 2.8.7

-- Configuring incomplete, errors occurred!
patryk@telperion:~/llvm/build$
</pre>

The solution is to download and compile CMake yourself, using the existing CMake 2.8.7 and then replacing it.

* Download the latest CMake version from the CMake web site, and uncompress iin a folder
* Create a _build directory in the CMake sources foldert
* From the _build directory, run the following commands to build and install CMake from sources:

<pre>
cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr
make
cpack -G DEB
sudo apt-get remove cmake cmake-data
sudo dpkg -i cmake*.deb
</pre>

You probably will also need to upgrade to a newer GCC:

<pre>
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.8 g++-4.8
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 50
</pre>

If running make -j8 in llvm failed with a "syntax error in VERSION script" error,
you may be able to overcome it by doing the following steps after getting the error:

<pre>
# After make -j8 returned a syntax error in VERSION script error
cd ~/llvm/build
make clean
cd ~/llvm/build/tools/lto
make -j8
cd ~/llvm/build
make -j8
</pre>
