I got X11R3 off expo and tried to compile it on a IBM RT running
4.3. This happened during the "make install" phase. "make world" had worked
without complaint.
vga % make
rm -f vgaData.o
/bin/hc -c -O -I. -I../BSDrt -I../ppc -I../../../include -I../../../.././X11
-I../common -I../../mfb -DUNIXCPP -DNOSTDHDRS -DHCVERSION=21004 -DBSDrt
-DATRIO vgaData.c
E "vgaData.c",L115/C2: vgaSetColor
| Type "void(unsigned long color,short r,short g,short b)" is not assignment
compatible with type "void(*)()".
1 user error No warnings
*** Exit 8
Stop.
I built the Xibm server without -DVGA, but it just blanks the screen and dumps
core when I try "xinit" (this is on a mpel).
Any tips would be appreciated.

Version 2.1 of the High-C compiler (i.e. /bin/hc) is so brain dead that even people in IBM don't use it. Modify utils/imake.includes/Rt.macros to get this to happen globally. Also remember to change HCRevision in the same file. One other thing that I have done when porting programs from other C compilers to High-C is to stuff the following in some include file or other that is used by everything. <X11/X.h> comes to mind. /* * Totally gross and disgusting hack to get around High-C on an IBM RT * treating `char' differently than most other compilers. Along with * assorted other things. */ #if defined(__HIGHC__) && defined(ibm032) pragma Off(Char_default_unsigned); pragma On(Char_is_rep); pragma On(Parm_warnings); pragma On(Pointers_compatible); pragma On(Pointers_compatible_with_ints); #endif /* defined(__HIGHC__) */ This seems to make High-C 1.4 behave like most other C compilers I have encountered. Some of the pragmas may not be neccessary but they do not seem to cause any trouble. -- Dan Ehrlich <ehrlich@shire.cs.psu.edu> | Disclaimer: The opinions expressed are The Pennsylvania State University | my own, and should not be attributed Department of Computer Science | to anyone else, living or dead.

Yeah, the problem is that hc is somewhat ansi conformant; you need to change the line: vgaSetColor, /* void (* setColor)() */ to something like: (void (*)()) (vgaSetColor), /* void (* setColor)() */ OK, I know some of these parenthesis are unnecessary, but I like 'em. Anyway, my experience is that X11 R3 on the 4.3 RT is too buggy to be worth the time. Anyway, this should fix that problem.

I've built the X11R3 distribution with the Metaware Compiler distributed
with the December 22, 1988 Release of 4.3 (2.1n, according to cc -v),
with the Purdue 2.1 speedups, and 'official' patches 1-9, with no
problems whatsoever. I've built servers for the megapel, apa16, and
vga/8514 and they all work fine.
I believe that I made some changes to get it to compile under the
previous release, but I'm not sure. I think I can hunt down the diff
file(s) if you want.
