LINK : error LNK2001: unresolved external symbol _WinMainCRTStartup

[Brian_A_]

When compiling my code from a command prompt using a make file, this is the error that I am encountering:

LINK : error LNK2001: unresolved external symbol _WinMainCRTStartup

Here is the results of my make.

It would be more inviting to look through the transcript if you used the "syntax highlighter" tool instead of pasting dozens of lines with the line breaks removed.

You probably have errors in the makefile. This line sums it up:

No object files were included in the link command issued through the driver ifort.
