Hi Sean,

Did you get anywhere with this?

Thanks

Subject: Re: [Openexr-devel] Halftest not working

Hrm, it's still not working. I added halfExport.h and had to resolve some issues like "max isn't defined", and include <algorithm>. I'm not sure if that would mess things up.

My output when I build/run halftest is 

basic arithmetic operations:

 f1 = 1, f2 = 2, h1 = 13.6875, h2 = 18.1719

 h1 = f1 + f2: 13.6875

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\v120\Microsoft.CppCommon.targets(132,5): error MSB3073: The command "C:\Users\Sean\Downloads\ilmbase-2.0.1\ilmbase-2.0.1\vc\vc8\IlmBase\HalfTest\..\x64\Release\HalfTest.exe

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\v120\Microsoft.CppCommon.targets(132,5): error MSB3073: :VCEnd" exited with code -1073741819.

========== Build: 0 succeeded, 1 failed, 2 up-to-date, 0 skipped ==========

obviously since in the code it's doing half h1(3), something is not right. I checked toFloat.h and eLut.h with premade ones on someone's github, and they match so that isn't the problem. I don't know if it makes a difference that I am doing this on a Surface Pro, and have converted it to vs2013.

If anyone has any other ideas I'd appreciate it.

There is a branch which fixed that and a pull request. The owner is epu the branch is github-60.
I don't know how far along the integration process of the fixes into the development branch is....

On further inspection, half(3) does not give me 3. It gives me some random number like 13.6897. dunno what's going on.

Hi,

When I try to build IlmBase for x64, the compilation works. However, when I run halftest.exe, it seems that the floats are not getting assigned to the half's correctly. testarithmetic fails on the first asset ( h1 = f1 + f2;   assert (h1 == 3); ) h1 still shows its original value (f1 + f2 is not getting stored into h1).

I'm using vs2013 preview on a win 8 x64 machine. 

Thanks,

Sean
