Compiling CWB from source under Linux

Compilation and installation of CWB version 2.2.b98

You just need a working linux installation. If you're using a “desktop” linux installation (such as Ubuntu), you may need to install the following packages:

• autoconf
• bison
• flex
• gcc
• libc6-dev
• libncurses5-dev

So, in case they are not installed, all you have to do in Ubuntu (or other debian-based distros such as Mepis) is:

sudo apt-get install autoconf bison flex gcc libc6-dev libncurses5-dev

Get the source code from here, and unpack it:

tar xf cwb-XXXXXX.tgz

Enter the new directory:

cd cwb-3.0

First you need to include the right platform in config.mk using your favorite editor, we used nano:

nano -w config.mk

Change the line:

include $(TOP)/config/platform/darwin-g4

to:

include $(TOP)/config/platform/linux

This section of the file should now look like this:

Then we compile the different components, one at a time. First we clean and check dependencies:

make clean
make depend

Then we compile the corpus library:

make cl

Editline is a bit of a problem at the time, hopefully it will be fixed very soon, but right now you have to follow this procedures to compile it correctly:

cd editline
make clean
autoconf 
./configure
cd ..
make editline

Then the utilities

make utils

Finally we compile cqp:

make cqp

Now we're ready to install the whole toolkit:

sudo make install
