Sedric the page I referenced shows that GCC/G++ are required to compile XaraLX. KDevelop needs to be configured to compile GCC/G++ source.

See the references in the google search http://www.google.com/search?hl=en&q=gcc&as_q=kdevelop

Very few Linux developers ever visited these forums. The members of Talkgraphics are mostly users of graphics software rather than developers.
