[Mapserver-users] Re: Mapserver Compilation on Win 32

[Ed McNierney]

Rich -

Sorry - Gayathri emailed me and I answered this question directly.

In order to support some multithreading experiments I'm doing under
Windows, I compile my MapServer tree with the /MT switch so the
multithreaded version of the C runtime library is used.  This is the
LIBCMT referred to.  Gayathri was having trouble building the extremely
small but annoyingly complex regex library, so I sent him my makefile,
forgetting that it had the /MT switch set.

The linker will complain (as below) if some of your modules are looking
for one version of the library, and others want a different version,
since obviously only one can be used.

I am not an expert on win32 compilation, I just struggle thru it, so
don't 
take any of this as authoritative advise. From your error messages it
looks 
like 2 packages are defining the functions with the same name so you
need 
to get rid of one of them. What is LIBCMT? I don't seem to have it in my

source tree. Can you eliminate it from the make file (comment it out)?

I thought regex came with the mapserver source distribution, maybe not. 
Anyway,I posted my copy of regex as "regex-0.12.zip" at 
http://www.greenwoodmap.com/mapserver/

Sorry I don't have any more specific advice, but do keep trying. I will 
post this reply to the list so that others may comment.
