Thank you for your comment
I'm working in Mac version, but my work is very slow because I'm a beginner in Mac and Linux.
I installed Ubuntu 8 in a computer some time ago and tested Eclipse+GCC, but I have a lot of things to learn yet. Do you advice me Eclipse IDE to work in Linux?
I work in Windows with VisualStudio 6 and I did not find a similar IDE for Mac or Linux.
