With my tries i got: As per the messages, the source files xyz.f and new.f both contain a main program in terms of the program unit the compiler has seen in those files.

That's what it's telling you. Well basically 1 project = 1 program.

After getting the syntax correct, had several errors as i worked through it, eclipse now complains: You can't link multiple stand alone (meaning they each have a 'main') programs into a single one.

第一次写多文件结构，编译时碰到了 > multiple definition of ’main' 提示以及编译错误：[error] ld returned 1 exit status ，遇到问题自然要解决，这里记录下解决办法： 1.重复定义。> multiple definition of main’ `意思就是函数或变量被大量重复定义了！注意检查代码是否有重复. Hi, i have developped a code on my laptop. Je ne connais pas cette erreur c'est la 1ere fois que je la vois et je ne comprends pas.

With My Tries I Got:

No other errors or warnings or informational flags. This is a single app, project explorer shows a single app. Both main.cpp and file2.cpp have a main().

Now I Am Trying To Compile This Code On A Opteron Cluster With Pgi Fortran Compiler But Before The End The Compilation Stops With The Following Msg Error:

Main.cpp file2.cpp where the first three should end up in one executable and the file2 should end up in another executable. And you can only have 1 main () per program (otherwise how is the computer supposed to know which main you want to use?). After getting the syntax correct, had several errors as i worked through it, eclipse now complains:

*** [All] Error 1 So I Was Just Wondering If I'm Including Things Or Putting Class Definitions Wrong Somewhere, And If I Am, Why I Can't Do It This Way?

But each different.cpp files should have their own main() function. To remove the file from the build right click on the file name, then select remove file from project. You can only have one function called 'main' in your program.

Ld returned 1 exit status make: Seulement au moment de tester le programme, j'ai l'erreur multiple definition of 'main' à la ligne 9. Multiple definition of main means you have written main function more than once in your program which is not correct according to c language specifications.
