GNUstep under Ubuntu Linux

2014-01-09T14:32:06Z

Traumflug: 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. 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]].

You can compile the following code with:

clang `gnustep-config --objc-flags` `gnustep-config --objc-libs` -fobjc-runtime=gnustep -fblocks -fobjc-arc -lobjc blocktest.m

clang `gnustep-config --objc-flags` `gnustep-config --objc-libs` -fobjc-runtime=gnustep -fblocks -lobjc -ldispatch -lgnustep-base Fraction.m helloGCD_objc.m

cat > blocktest.m << EOF

int main() {
void (^hello)(void) = ^(void) {
printf("Hello, block!\n");
};
hello();

[frac setDenominator: 3];

# ADDITIONAL OPTIONAL STEPS FOR INSTALLING GUI AND BACK
# (i.e., if you're running Ubuntu Desktop)
# ------------------------------------------------------

sudo aptitude install -y libjpeg-dev libtiff-dev
sudo aptitude install -y libcairo-dev libx11-dev:i386 libxt-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

</pre>

* 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))

<b>Ubuntu 12.04 Help</b>

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 <b>after getting the error</b>:

<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>
