To: John Scipione: Thank you for the tip to use Paladin, I stopped using it because I could not figure how to compile my device driver code with it, but the other code did work with it so I will go back to using it again. The device drivers that compiled ok under GCC2 were compiled on the standard nightlies, but when I boot x86_64 Haiku and try to compile them there they would compile but when placed in the same locations as the Hybrid-Haiku I received odd messages about bad data and they would not work. I tried pastebin.com. I am not sure it is the thing for this but I will give it a try. I will move all my future inquires to haiku-3rd-party. To Barrett: Yes I had found http://api.haiku-os.org/compatibility.html it is not enough in itself. To Paul Davey: The drivers were compiled in the x86_64 nightly which I understand is already GCC4 only. To Andrew Hudson: Thank you for your offer, I will try to not abuse your help so let me try the other suggestions first. To Alexander G. M. Smith: I am not concerned about supporting BeOS anymore, Haiku-OS all the way for me. Besides I don't want to just deliver binaries, I hate downloading a program from BeBits or Haikuware then finding out it will not work with the latest Haiku-OS. In the past if I got the source code I could make changes and get some programs running again or steal out useful bits of code. But since Haiku-PM I found some of the changes to the develop folder have prevented me from compiling older code. Anything I write *WILL* always come with the source code! PS. Yes,I know that some of my code is a horror to look at,which is another good reason to rewrite it.
