Re: [Openexr-devel] Windows CMAKE build failing

[Mike Wong | ax.gmail]

Would be good not to generate it.  I bumped into this problem when I was cross-compiling an iOS port a while ago but I guess the table is designed to be generated by the target platform.

For the Windows related build issues, if it is built by VC10 or later, just make sure b44ExpLogTable 's current directory has the freshly built Half.dll there as VC10+ runtime library always looks for current directory first.  For anything pre-VC10, the safest way is to embed a manifest into the executable to instruct the runtime where to find Half.dll, sorry it's Windows :(

I seem to recall that we spoke a while back about deprecating this part of the build process. That table should be pretty well defined. Though, we should keep the generator for unit tests.

Yes, that's what it is, and it occurs when you're building shared libs (the default).  If you're using command line tools like nmake or msbuild, then it's easy to work around this, but it's more of a problem when using the Visual Studio IDE.

The same will be true when trying to execute unit tests.

If any CMake guru knows how to handle this elegantly, I'm all ears.

The problem is that b44ExpLogTable relies on the Half.dll and it is not finding it.
Placing a:

set PATH=%PATH%;F:/code/lib/Windows_64/lib

(my %ILMBASE_PACKAGE_PREFIX%/lib directory)

solved the problem.
