Are you familiar with make files in Linux? I used CMake to compile the codes in Linux. I recently had to compile C codes to executables and fortran codes as a library. It worked for me.

 HI BBCnews,  Thanks for your reply. Its been just a couple of days I am working fortran in LInux environment. During a lot of search in the internet I knew a little about the make files but I don't know how to make one. I would appreciate if you could tell why I got that error "undefined reference to main_". Thanks. Anjeep

 Hi bbcnews,  I found the source of my error. Actually I didn't care LInux is case sensitive. When I changed the case of the input files then the program worked perfectly. In windows I didn't have any problem with case of the input files. Thanks. Anjeep
