What is your question?

Doesn't this explain the source of the problems already:

 You are using gcc version "4.5.2-8ubuntu4)". The version currently supported with MEX is "4.3.4"

my question is how i remove this error when i m compiling any c file in matlab thru mex compiler under linux...........

i hope now u understand my problem.........basically i m new with "mex tool"

[abukaf]

i m reaaly troubling.....

What is wrong with installing the GCC version Matlab supports? Did you even try it? When you decide not to use the suggested compiler, follow the instructions you find in the net, e.g.:
