Re: Building against GnuWin32 binaries of libjpeg etc?

Hmm... I have already found some problems with some simple
tests. I 
can't seem to link against the files in their installed
locations. Any 
suggsetions on how to fix this? Could it be that there's
some problem 
with the linking of the c:Program 
FilesGraphicsMagick-1.1.10liblibGraphicsMagick.dll.a file
and the 
c:Program
FilesGraphicsMagick-1.1.10binlibGraphicsMagick.dll files?

I'm thinking of ldconfig on Linux, is there something
similar at play 
here? Is it possible that the 'make DESTDIR' trick that I
used doesn't 
work correctly on Windows?

Cheers
JP
