Can't link C object library (.obj) to Fortran project

[Gordon_B_]

I am trying to link a C object library to a Fortran project in Visual Studio 2017 running under Windows 10 on a 64 bit Intel Machine.

The linking was working and I had been debugging the project but something changed when I moved the project from an external hard drive to an onboard hard drive.

The file RayOpt.obj does exist in the specified directory.  the unresolved _mcea is in the RayOpt library

I am getting the linker messages below:

1>------ Build started: Project: Traj2D, Configuration: Release Win32 ------
1>Linking...
1>1>------ Build started: Project: Traj2D, Configuration: Release Win32 ------

I was hoping to work on this over Xmas but am stymied by not being able to link.

Would appreciate any help I can get

Thanks

Posting the BuildLog.htm file might be helpful. At a glance I am also suspicious of the ";" at the end of the OBJ name is it looking for a file the has ";" at the end ?

Please also attach the .vfproj file for the project. Like Andrew, I am guessing that you haven't correctly specified the library dependency.
