Re: [Openexr-devel] VC7 compile errors

[Florian Kainz]

Hi Martin,

with Visual C++ .NET, version 7.1, OpenEXR should compile
right out of the box, but version 6 and earlier versions
cannot compile OpenEXR at all.

With version 7.1, all you have to do is open the "OpenEXR
Visual Studio Solution Object" in the vc\vc7 folder, and
hit F7.

When you compile OpenEXR 1.2.0 with Visual C++, you will
get lots of warnings, but the code should compile and pass
all confidence tests.  OpenEXR makes extensive use of implicit
type conversions, and the Visual C++ compiler flags most of
them as potential bugs.  This will be fixed in the next
release of OpenEXR. (If you are interested, check out the
latest code from CVS; the fix was checked in yesterday.)
