Please help me I am a new user to linux and has made a project in eclipse IDE for linux. The project is running in the IDE but how am I supposed to make a executable for this???

go to workspace directory -> project directory -> Debug and there will be executable file

Thanx i got executable but when i try to run it says Segmentation fault y so? even though the program is running in the IDE

If you're talking about your program, post your code.

the program is running fine in the IDE but when I try to run the resulting executable file it says "Segmentation Fault"

try to copy executable form debug directory to project directory and run it... or post your code :}
