pfstools can be compiled with Visual Studio using CMake build system. This file contains some troubleshooting hints.

Refer to README for details on building pfstools using CMake.

The compilation was tested with Visual Studio Express 2013.

Note that this compilation procedure is an alternative to using cygwin (refer to README.Cygwin). 

=== QT ===
Download and install Qt4 (not Qt5) for Visual Studio from: http://qt-project.org/downloads

Then add entry to CMake variables:
QT_QMAKE_EXECUTABLE:FILEPATH=E:\Qt\4.8.5\bin\qmake
where E:\Qt\4.8.5\bin\qmake should be replaced with the path to qmake on your computer.

You may need to compile in Release mode. Otherwise some DLLs might be missing.

=== OpenEXR ===

Compiling OpenEXR on Windows with Visual Studio is not a task for faint hearted. Be prepared to fix quite a few issues with the code.

* If the compiler complains about missing "__builtin_trap()", add 

#define PLATFORM_WINDOWS 1

to config/IlmBaseConfig.h 

see

https://lists.nongnu.org/archive/html/openexr-devel/2013-12/msg00001.html

* If the compiler complains about "std::max", add missing include in all offending files:

#include <algorithm>
