New Revision: 2765
URL: http://svn.gna.org/viewcvs/mysqlpp?rev=2765&view=rev
Log:
- Added paragraph to README-Visual-C++.txt explaining the best way to
get 32-bit builds out of VC++ 2008 and newer.
- Clarified the paragraph explaining how VC++ 2012 wrecks the library
linkage paths when converting the vc2008\* projects, so that the
solution is more readily apparent.

versions of Visual C++, but beware that the upgrade feature tends
to be problematic.
- When converting the VC++ 2008 project files to VC++ 2012,
- I found that it will screw up the output file names for the
- libraries, so that none of the executables will link properly.
- This problem is detected by the migration process, so that even
- though the tool doesn't know how to fix it itself, you can fix
- it up manually afterward.
+ If you want to do a 32-bit build on VC++ 2008 or newer, it is
+ easiest to open the vc2005\* project files and let Visual Studio
+ upgrade them for you. The alternative, starting with the vc2008
+ files, requires that you add a 32-bit build option to all of the
+ many targets in MySQL++, then optionally delete the 64-bit targets.
+ This is a lot more work. Plus, it only works if you have the
+ 64-bit compilers installed, since Visual Studio will refuse to
+ open project files where all targets must be built with compilers
+ that aren't installed, even if your goal is to immediately adjust
+ them to use compilers that *are* installed.
+
+ When converting the VC++ 2008 project files to VC++ 2012, Visual
+ Studio will change the output directories from Debug to Debug\x64
+ (and similar for Release), but it won't also change the link paths
+ from Debug to Debug\x64, so that the library and examples will
+ compile but not link. The migration tool detects that there is
+ a problem, but it can't fix its own mess. You have to manually
+ fix it.
There were also problems in VC++ 2010 when you had converted 32-bit
VC++ 2008 projects and then were trying to switch them to 64-bit.
