It seems that there are some .dsw files in the SYMPHONY 5.0 distribution 
that are in Unix format rather than in Windows format. To solve this 
problem, just open them in Word Pad and resave them again. Then 
everything should work fine. Alternatively, just download the latest 
source code from CVS or download a tar file at

You have apparently not compiled the COIN component CGL. This is not 
needed for the VRP solver anyway. If you set USE_CGL_CUTS to FALSE in 
the Makefile, this should fix it. Again, however, I would download the 
latest source code and use that.

Cheers,

Ted
