Other things that differ are the include and linker paths. Since we are launching VS with out custom batch file, we need to update our environment to target Windows 64. In VsVersion, we need to set TARGET=X86_64.
In 64-bit builds a different configuration is used in Visual Studio:
Additionally, one has to be sure that x64 is set as the target for static libraries built in the project.
If any mismatches are detected between x86 and x64, the compilation will fail with the following error message:
fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86'
Another couple of tips if you run into compilation errors is to
- make sure that you clean the solution
- Check that the correct lib and bin directories are being used
- Doublecheck the obj files that are created during compilation are 64-bit. You can do this by running dumpbin /HEADERS somefile.obj
If all went well, you should be able to load the 64-bit version of the filter in the 64-bit version of GraphStudio. You might have to make some tweaks to the paths depending on the platform you're building on, and on the target platform.
