When I compile some code using "Build" in the Plato IDE (fortran 95 with C) I get the following when using Checkmate Win32:

WARNING the following symbols are missing:
ezsdi C:\SwitcapSource\sw2_1.2\CheckMate\Win32\ezinit.obj

ezinit.f is the fortran file, and it calls the c routine ezsdi.

When I compile using Debug Win32 the symbol is not missing and the link is successful. I am using the C_EXTERNAL Ftn95 directive to call the C routine.

I understand most of the differences that Checkmate feature brings, but I can not figure out why this referenced object is not found when compiling using the Checkmate. Any ideas?

Have you declared ezsdi as C_EXTERNAL etc. in your Fortran code?
This would correspond with extern "C" in your C code.

See the standard header files for examples of how to do this. Further details appear in FTN95.chm.

I don't think that you have to do it this way but the root of the problem may be that the Fortran requires extra arguments in CHECK mode and, for some reason there is a mis-match when linking.

I have the C_EXTERNAL in the fortan code. In fact, the code appears to work when complied with Debug Win32 mode set, but not the Checkmate mode. That is what is confusing me. I'm sure it is some linker options, but I have not been able to crack the code on which ones may not be set or may be set to a wrong parameter.
