Hi, 
I downloaded the version 2.2.1 and I built it using MinGW the instructions in 

https://sourceforge.net/apps/mediawiki/qtpfsgui/index.php?title=Compiling_on_Windows 

After some time I've built and compiled it. This instructions seems to be from 2009...
I've read also in the INSTALL file of this version that it's possible to satisfy all the runtime dependencies by using DLLs from

http://sourceforge.net/projects/qtpfsgui/files/Windows%20DLL%20Package/

but the INSTALL file says that this is deprecated and the fact is that Im getting runtime errors. Any suggestion about what to do in order to build and run Luminance HDR using MinGW in Windows? Thanks in advance for your help!
