I am having some rather crazy problems with my recently installed GNU C compiler on the Sun4 platform. The installation and everything seems to have gone fine and the compiler works with regular ansi files like a charm. But, when it comes down to files with inbuilt headers calling the xview libraries, it messes up like mad. The compilation throws out some warnings and errors in linking. After discussion with some of the other local hackers, I have come to the conclusion that maybe the openwindows platform, i.e. header files are not exactly ANSI-compatible. I am sure there must be plenty of you out there who must be using GNU C and its reputed ansi facilities in conjunction with the Xview libraries. I would appreciate any suggestions to improve my situation. Thanks in advance. Aashish Malhotra hista@jane.uh.edu OR malhotra@cs.uh.edu

The header files for XView version 2 are set up to provide K&R C, ANSI C, or C++. Unfortunately, the ANSI C version has syntax errors (!). The problem is this: When using a variabel number of arguments for a function in ANSI C, you use the ellipsis notation, ie int printf (char*, ...); XView make use of this a lot. For some functions, XView does not want to tell anything about the arguments, hence int shhhh (...); BUT this is illegal. "...there must be at least one named argument;...", (K&R, 2.ed., p 155). To do that, one must say int shhhh ( ); That's an "old-style" declaration, with no type checking at all. Below is a patch for XView that fix the problem. save this article and go to ..../openwin/include/xview and say patch -p1 < xview.patch If it complains about a reverse patch, just say "y" (I always mess up the diff command. Sorry). Happy Hacking!
