This is how I got FreeTDS to compile on Windows 7 Professional with Visual Studio 2008.
1. Install Visual Studio 2008 (a.k.a.: Visual Studio 9.0)
2. Download the FreeTDS 0.91 source tarball and extract it somewhere. I chose C:\Users\marca\src\freetds-0.91.
3. Open a Visual Studio 2008 Command Prompt.
4. Change to the directory with FreeTDS:
cd C:\Users\marca\src\freetds-0.91
(or whatever you chose)
5. Give this a shot — it will fail probably:
nmake -fNmakefile -nologo apps PLATFORM=win32 CONFIGURATION=debug
6. You will get a bunch of errors that look like this:
c:\users\marca\src\freetds-0.91\include\tds_sysdep_private.h(239) : fatal error C1083: Cannot open include file: 'inttypes.h': No such file or directory
7. Fix the inttypes.h error — edit win32/config.h and comment out this line (line 92 for me):
#define HAVE_INTTYPES_H 1
8. If you repeat the above nmake command, then you’ll get a new error:
c:\program files (x86)\microsoft visual studio 9.0\vc\include\stdio.h
(358) : error C3163: '_vsnprintf': attributes inconsistent
with previous declaration
c:\program files (x86)\microsoft visual studio 9.0\vc\
include\stdio.h(350) : see declaration of '_vsnprintf'
9. Fix the _vsnprintf error by editing include/tds_sysdep_private.h and commenting out the second instance of this line (line 96 for me):
#define vsnprintf _vsnprintf
10. Repeat the nmake command and this time it should succeed and you will end up with a tsql.exe file.
