Build Two Projects in a Workspace

[ignacionieto]

Hi All
Im using Code Blocks 10.05 on Ubuntu 11.04. I got a Workspace with two projects one a client the other a server.
I try to build both to test in on a Local Machine but everytime I try to run both only one of them is build. Then I try to build the other one, but I cant. The option appear block.

I have check information at some tutorials but I havent found the answer to my problem. How can I build two projects (server and client) in the same Workspace for me to test the TCP/IP communication ?

I had used Xcode before with the same files and works, but right now I need to compile and build it on a Linux Box.

thanks in advance.
