Hello,
May I ask a question about using libraw with mingw?
My OS is Windows 7 and I installed MSYS and mingw492_32.
I download LibRaw-0.17.2.zip and extract it.
On command prompt, I executed
sh ./configure
mingw32-make -f Makefile.mingw
and could get lib\libraw.a

I tried to test this static library with simple_dcraw.cpp in samples folder.
g++ simple_dcraw.cpp -o simple.exe -Ilibraw -Llib -lraw

I got the following error messages:

Did I set something incorrectly? And I saw Qt project files on buildfiles. I
tried to compile in Qt, but only gives error messages.
