Hi all, I'm able to compile the .NET code generator with GHC without compiler errors, but now I have the linkage error below. (In fact there are other similar messages, this is only an example). This is strange because the *.o/*.hi files were all generated without error messages. Has anyone any idea about how to solve it?
