Mention the GNUstep weekly PPA. Right now this PPA is empty, but will be populated the next few days.

 +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.

Revision as of 14:32, 9 January 2014

The most simple way to get an up-to-date installation of GNUstep on Debian or Ubuntu is to add the 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.

sudo aptitude install -y libjpeg-dev libtiff-dev

cd ~/core/gui
./configure
make -j8
sudo -E make install

cd ~/core/back
./configure
make -j8
sudo -E make install

You can compile the following code with:

clang `gnustep-config --objc-flags` `gnustep-config --objc-libs`  -fobjc-runtime=gnustep -fblocks -lobjc -fobjc-arc -ldispatch -lgnustep-base -lgnustep-gui  guitest.m



cat > guitest.m << EOF
#import <AppKit/AppKit.h>

int main()
{
NSApplication *app;  // Without these 2 lines, seg fault may occur
app = [NSApplication sharedApplication];

NSAlert * alert = [[NSAlert alloc] init];
[alert setMessageText:@"Hello alert"];
[alert addButtonWithTitle:@"All done"];
[alert runModal];
}
EOF



  • General Note: When compiling, it is generally good to tell clang both the family and version of the runtime: -fobjc-runtime=gnustep-1.7

(The current version number can be had by looking at the latest ANNOUNCE filename in http://svn.gna.org/svn/gnustep/libs/libobjc2/trunk/ (e.g., ANNOUNCE.1.7))


Ubuntu 12.04 Help

In Ubuntu 12.04 Desktop, I found that running make -j8 in llvm failed with a "syntax error in VERSION script" error.

I was able to overcome it by doing the following steps after getting the error:

# 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
