I am attempting to build a DLL using DMC 8.34 and the tool chain from the CD. My initial attempts simply used the '-mn -WD' options and listed the code files. When that failed, I fired up the IDDE and set up a Win32 DLL project. In both cases, I get the same giant list of errors involved being unable to export symbols. I am sure that I'm just doing something foolish. In particular, I have not added GDI32.lib and other system libraries that I need to build the project. I don't directly see how that would cause the "cannot export" errors, but I certainly see how it would cause the "undefined" errors. Here is an abbreviated example of the output. I cut out most of my member functions, because they were boring. I left the "undefined" errors for the various library functions alone, in case those were somehow useful. Any suggestions would be greatly appreciated.

Mac Reiter <Mac_member pathlink.com> Never mind... After I included gdi32.lib, kernel32.lib, and comdlg32.lib on my build line, the imports worked and, suddenly, the exports were perfectly happy. Don't know why, but it works, and I've got a DLL. Sorry for the wasted bandwidth.
