Hi Peter
Yes this is definitely a problem with the OpenVG package.
Although I wrote the package I don't know enough about the minutiae of
Windows .dlls to sort this out directly (even though I did write most
of the library on a Windows machine). I could try to and write a
cabal+makefile build rather than a pure cabal one to follow the
example of the OpenGL and GLUT libraries, though I don't know if that
would work. With my current OpenGL and GLUT installation[1] on Windows
I can only run GL programs from GHCi rather than compile them.
Please let me know if you want me to try a cabal+makefile package,
though the turnaround might not be quick.
Best wishes
Stephen

I followed the instructions on how to build OpenVG on Windows. It works fine when I run the examples using "GHCi -lopenvg32", but when compiling it with "GHC --make -lopenvg32" I get a bunch of linker errors, like C:\Program Files\Haskell\OpenVG-0.1\ghc-6.10.1/libHSOpenVG-0.1.a(Paths.o):fake:(.text+0x82): undefined reference to `vgInterpolatePath' C:\Program Files\Haskell\OpenVG-0.1\ghc-6.10.1/libHSOpenVG-0.1.a(Paths.o):fake:(.text+0x40d): undefined reference to `vgModifyPathCoords' etc However it does seem that the libopenvg32.a file contains all these undefined references, and it is in the gcc-lib directory of GHC. I'm a stuck. Any hints? Thanks, Peter
