Building mym on 64-bit Windows 7

Has anyone been able to get mym ( http://sourceforge.net/projects/mym/ ) to build on a 64-bit Win7 machine? And if so would you mind posting or linking your steps to do so?

My particulars:

Windows 7 Enterprise, 64-bit OS

MATLAB Version 7.13.0.564 (R2011b)

Microsoft VS 2010 Ver. 10.0.30319.1

MySQL Ver 14.14 Distrib 5.5.21, for Win64 (x86)

I ran "mex -setup" and I was able to compile and run "yprime.c"

I downloaded and installed zlib ( http://www.zlib.net/ ), which is what the readme file for mym says to do.

Here is the mex command that I am using:

mex -IC:\zlib-1.2.6 -I'C:\Program Files\MySQL\Connector C 6.0.2\include' ...
      -L'C:\Program Files\MySQL\Connector C 6.0.2\lib\opt' ...
      -L'C:\zlib-1.2.6' -lzlib -lmysqlclient mym.cpp

I get a bunch of "already defined in MSVCRT.lib" error messages. e.g.:

LIBCMT.lib(tidtable.obj) : error LNK2005: _encoded_null already defined in MSVCRT.lib(MSVCR100.dll) 
LIBCMT.lib(invarg.obj) : error LNK2005: _set_invalid_parameter_handler already defined in MSVCRT.lib(MSVCR100.dll) 
LIBCMT.lib(crt0dat.obj) : error LNK2005: _initterm_e already defined in MSVCRT.lib(MSVCR100.dll)

I admit that I'm stumped at this point and there is not a whole lot of helpful info out there on the world wide web. Any suggestions would be greatly, and I mean greatly, appreciated.

Thanks, Bill

Finally got this stupid ** to work. Add COMPFLAGS="$COMPFLAGS /MT" to your command. So it should look something like:

mex -v COMPFLAGS="$COMPFLAGS /MT" -I"C:\zlib-1.2.6" -I"C:\Program Files\MySQL\Connector C 6.0.2\include" -L"C:\Program Files\MySQL\Connector C 6.0.2\lib\opt" -L"C:\zlib-1.2.6" -lzlib -lmysqlclient mym.cpp

Or, in my case:

mex -v COMPFLAGS="$COMPFLAGS /MT" -I"C:\Program Files\MySQL\MySQL Server 5.5\include" -I"C:\Program Files\zlib-1.2.7" -L"C:\Program Files\MySQL\MySQL Server 5.5\lib" -L"C:\Program Files\zlib-1.2.7" -lz -lmysqlclient mym.cpp

Thanks, this was very helpful!

A couple notes:

- I had to use '-lzlib' instead of '-lz'

- Here's a discussion of the /MT switch (it causes your app to use static version of runtime library) http://msdn.microsoft.com/en-us/library/2kzt1wy3(v=vs.100).aspx

- I had to build zlib from source. Here's how

1. Download from here: http://zlib.net/zlib127.zip
2. Start...All Programs...Microsoft Visual Studio 2010...Visual Studio Tools...Visual Studio 2010 Command Prompt
3. Wait for several minutes till it finishes updating environment.
4. cd C:\zlib-1.2.7
5. nmake -f win32/Makefile.msc

Thanks. I got it to work, but had to remove the

COMPFLAGS="$COMPFLAGS /MT"

So the overall command:

mex -v -I"C:\Program Files\MySQL\MySQL Server 5.7\include" -I"T:\zlib-1.2.11" -L"C:\Program Files\MySQL\MySQL Server 5.7\lib" -L"T:\zlib-1.2.11" -lzlib -lmysqlclient mym.cpp
