RE: [Openexr-devel] VS2003 vs. VS2005 C++ ABI

[Nick Porcino]

The ABI changed VERY slightly; name mangling for IIRC partial template
specialization was updated to eliminate some ambiguities. So the
binaries are link compatible for the most part. I haven't spotted that
the name mangling changes affect OpenEXR.

The cross linked standard libraries that Kevin mentions are a big deal
though. For that reason, I'd say it would be cleaner to distribute vc7
and vc8 prebuilt versions.

Drew,

if you compile with 2005 you will get a different runtime linked to
those parts of your app for sure (which can cause some problems if you
pass memory between runtimes), I tried it with some things here and it
'appeared to work' but it was not a very exhaustive test, so your
mileage may vary. I had Qt libraries compiled with 2005 running with
2003 compiled code.
