[Scons-users] MSVC is broken for x86 builds on x64 hosts

[Michael Hartmann]

All vcvars batch files work correctly. If you check the pastebin from my previous post you can see in line 144 that the env is set up correctly. The issue is that SCons decides to set it up a second time with the default Visual Studio.

As a check-list item, has the original environment been tested from the windows command-line using vcvarsall.bat to verify that the installed batch files are doing what is expected?

As I mentioned in the earlier thread, I had an installation of MSVC 2005 (8.0) x86 where the batch files to setup the environment to compile for x64 architectures was incomplete.  This was fairly difficult to diagnose.  Not all of the environment variables necessary for "vc/bin/x86_amd64/vcvars86_amd64.bat" were set correctly resulting in the build environment not being set correctly.  This problem is even worse if you have a different compiler on the system path when invoking the batch files.

In my case, the following environment variables needed to be added to the beginning of the generated msvc batch files:

@SET VSINSTALLDIR=C:\Program Files\Microsoft Visual Studio 8
@SET VCINSTALLDIR=C:\Program Files\Microsoft Visual Studio 8\VC
@SET FrameworkDir=C:\Windows\Microsoft.NET\Framework
@SET FrameworkVersion=v2.0.50727
@SET FrameworkSDKDir=C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0

It doesn't hurt to test out the environment directly to rule out the generated batch files to configure the environment.
