From: zetadublin on 9 Feb 2010 09:23 I have this trouble when trying to run a small code I have written. error LNK2001: unresolved external symbol _T@8 Debug/Simulated anealing2.exe : fatal error LNK1120: 1 unresolved externals Error executing link.exe. Can any one help ? Thanks

You could try a mind reading newsgroup. ;-) First guess: You forgot to declare an array name T so the compiler thinks it is a function which, of course, can not be found.

Perhaps if you took the trouble to give more information, you might find the answer yourself. I guess the following scenario where this might occur: You are compiling a program under an obsolete Windows-specific linking convention. You aren't using facilities such as IMPLICIT NONE to help catch undeclared/misspelled identifiers. You put something like t(i) in your source code, inadvertently creating a function reference.

The linker is looking for a function or subroutine named T with eight bytes of arguments (for Fortran, this almost certainly means two arguments of indeterminate type). When I encounter this kind of error, it usually indicates an argument count mismatch, but your mileage may vary; you're the one who knows what T is actually supposed to be.
