[Insight-developers] fstream instantiation

[Bill Hoffman]

This is not because of vcl_fstream.h which just includes <fstream>.
It is more likely a problem with mismatched compiler flags.
Please see Insight/Documents/VC_Custom_Projects.doc and be careful with the compiler flags.
Microsoft puts linker commands into .obj files.  This is because there
are several versions of the microsoft c++ libraries:  rtti, execeptions, new streams,
old streams, threaded, not threaded.   And most combinations of those.
The result is that the compile flags must match.
