Question
QUESTION: Dear Sir,
 I have a c++ exe file which successfully run on windows machine. Now i want to reuse the code which i have to run form linux. Is there anyway to convert exe to linux runnable format? I tried wine but itshows some error. Or is there any wayt to find the code of the exe?

Thanking you,
Umaimath

ANSWER: There is no good way to get the source code from the executable file, and even if it could be done, it may be of no use - there might be call to the windows api (win32) functions which won't be there in linux at all.

Unfortunately, wine does not run all windows programs. There are a few other good  (sadly non-free) alternatives.

Answer
g++ is the "GNU C++ compiler", which is standard with linux.
For the basics of hoe to compile and build programs, see:

If you have a large number of source files, using a Makefile is recommended.
