[Mapserver-users] MapServer Windows external symbol problem

Pericles,

Here is what I set my LDFLAGS in Makefile.vc after pointing to the PHP regex:
LDFLAGS =       /NODEFAULTLIB:msvcrt /NODEFAULTLIB:libcd 
/NODEFAULTLIB:libcmt /DEBUG

I'm speculating that it is caused by some code being built as debug while 
other is "release" code.  VC++ is kind of stupid when you try to mix the 
two together and says that those symbols have already been defined
