I am using VS2013 update 4.
I noticed this problem as I installed Parallel Studio 2017 update 2 and it persist for update 4.
Compiler output in VS output window prints warnings and errors in source files as usual. But the file paths it provides are messed up with forward slash before the file names.
My file is located at
If there is an error or a warning in the file, VS prints:
D:\tmp/a.f(1850): warning #6717: This name has not been given an explicit type. [IERR]
When I double click on the message to correct the issue, VS opens another tab for the file even though the file has already been opened in VS with d:\tmp\a.f path. Then, VS complains that the file has been edited outside of the source editor. This is SO frustrating...
Yes, this is a known problem, and has been fixed for Update 5. It is related to the fpp (Fortran Pre-Processor). If you do not need preprocessing for that file you can disable it.
I'm sorry for the inconvenience --
