Build EiskaltDC++ on Fedora 15 Lovelock 64-bit

EiskaltDC++ is a cross-platform program that uses the Direct Connect and ADC protocol. The direct connect client LinuxDC++ available in rpmfusion repos doesn’t yet support ADC protocol and hence doesn’t work with the DC++ Hub that has been setup in our hostel. I had to compile Eiskalt from the sources. Posting here the steps I had to follow for a rather painful build.

I am using Fedora 15 64-bit with GNOME 3 desktop.

First install the dependency packages, I had to install all these devel packages for my system, YMMY, see below:

sudo yum install cmake bzip2-devel xlib-devel zlib-devel openssl-devel qt-devel qmake boost-devel libupnp-devel aspell-devel libidn-devel lua-devel

cd to a desired directory where you keep your sources. Then,

git clone git://github.com/negativ/eiskaltdcpp.git #Clone the latest source from the official git repo
cd eiskaltdcpp/
gedit INSTALL & #Keep the INSTALL file handy, it lists all the dependencies required for the build
mkdir builddir
cd builddir/
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr -DUSE_QT=ON -DUSE_ASPELL=ON -DFREE_SPACE_BAR_C=ON  -DCREATE_MO=ON -DLUA_SCRIPT=ON -DWITH_SOUNDS=ON -DWITH_LUASCRIPTS=ON -DUSE_MINIUPNP=ON -DLOCAL_MINIUPNP=ON ../

If you get an error in the above step, check which dependency is missing and install it using yum

make -j9 #replace 9 with the number of cores in your CPU plus one. For my Core i7 CPU with 8 cores, it's 9
sudo make install

You can try running it by typing eiskaltdcpp-qt on the terminal. If it gives an error about libeiskaltdcpp.so.2.2 missing, just execute the following command:

sudo cp /usr/lib/libeiskaltdcpp.so.2.2 /usr/lib64/ -v

Now you can run Eiskalt without any problems.

Ubuntu Tips and Tricks – Part 1

Just learned some new commands on Ubuntu:

1. If sometime you get into a (big!) trouble such as the Gnome panels not loading but the desktop is visible, you can open the gnome-terminal using the key combination Ctrl + Alt + T (of course this is a good shortcut for normal desktop usage too).
2. Because of the above problem, you may want to create a bootable drive to reinstall Ubuntu, but how do you do that as you cannot load the Ubuntu Startup Disk Creator? Don’t worry there is a way – use the following command:

   usb-creator-gtk &

   to open the Startup Disk Creator utility. I am assuming you had some iso image on the hard disk of your computer. If not you can transfer it using a flash drive and cp command.

3. BTW if you don’t know how to mount a pen drive if it doesn’t happen automatically, use sudo fdisk -l after inserting the pen drive and take note of the device id, most of the times it will be /dev/sdb1. Then issue the following command:

   sudo mount /dev/sdb1 /mnt

   to mount sdb1 to /mnt directory.

4. And yeah there is sudo poweroff to shutdown the system properly.
