RE: [Openexr-devel] Building Visual C++ 2005 for x64 platform

All the project settings seem to be in order. Half.dll links fine, but not Iex.dll. It seems like createDLL.cpp is not mangling the symbols in Iex correctly for 64-bit.

I haven’t tried this myself, but is it possible that you have a std library mismatch, for example, something set to Multithreaded DLL, and another set to Multithreaded?

Subject: [Openexr-devel] Building Visual C++ 2005 for x64 platform

 

I am trying to build a 64-bit dll of OpenEXR for 64-bit Windows. I’m using Visual Studio 2005 (VC8). I started by downloading the math library (IlmBase) and trying to build the IlmBase solution. I created a configuration for the x64 platform. I had to make a few changes to get the “createDLL” project to compile. I changed the Output Directory and Intermediate Directory to match what the Win32 configuration had. Since the project uses a lot of hard-coded relative paths, these needed to be fixed from Visual Studio’s defaults.

 

This createDLL program runs the linker for the rest of the projects, and it has one line of code that controls the command-line options for the linker. I changed this line to be “X64” instead of “X86.”

 

At this point the “Half” project compiles and links successfully, but when I try to build the “Iex” project I get several linker errors, such as the following:

 

Iex.exp : error LNK2001: unresolved external symbol address@hidden@@

 

All the .lib, .def, and .obj files seem to be OK, so I can’t figure out what the problem is.

 

Does anyone have any tips for me? Thanks.
