Hi , I have just installed GPC-19990118 on a redhat 6.0 linux. I have some questions: a.. Is it possible to make the program development on the linux, and =when I am finished to cross-compile it to windows 98/windowsNT? b.. How do I work with graphics in GNU pascal, so that I am able to =use the same source to compile to both linux/windows execute files. c.. Where do I find information on the graphics tools to use in GPC. d.. I am working with the traveling salesmans problem. There I need to =make a 2-dimensional array which contain the distance between each =city/node. As I'am new to GNU pascal and pointers, I wounder if it is =possible to make some kind of pointer structure that is working faster, =use memory dynamically or smarter than using a 2-dimensionally array? kind regards, klaus ---------------------------- Klaus F.
