[C++-sig] building 32 Bit and 64 Bit extensions on the same machine

[Ronny Herzog]

Thank you,

but this does not seem to work. If I do this with
"bjam --address-model=64 -n"
I can see that it does compile it with my 32Bit Python and without 
setting the x86_AMD64 flag:
"[...]

cl /Zm800 -nologo 
@"C:\boost_1_50_0\bin.v2\libs\python\build\msvc-9.0\release\th
reading-multi\object\iterator.obj.rsp"
[...]"

I am using MS Visual Studio 2008.

Unfortunately, I cannot test it on an 64Bit machine right now.

I have Python26 (32Bit) and Python26 (64Bit) installed and I guess I 
have to inform bjam somewhere which one to use.

Thanks a lot,
Ronny
