There appears to be a compiler/library bug that prevents tkTrig.c -from compiling unless you turn off optimization (remove the -O compiler -switch). The problem appears to have been fixed in the 1.3-4 version -of the compiler. - ---------------------------------------------- -HP-UX systems: ---------------------------------------------- - -1. Configuration: - HP-UX Release 7.05 on a series 300 (68k) machine. - The native cc has been used for production. - X11r4 libraries and include files were taken from - internet archives, where as the server came with HPUX release 7.05. - - Problems: - Symbol table space for cc had to be increased with: -Wc,-Ns3000 - tkBind.c did not compile under -O: - C1 internal error in "GetField": Set Error Detected - *** Error code 1 - tkBind.c did compile without optimization (no -O). - -2. Note: if you have trouble getting xauth-style access control to work -(and you'll need xauth if you want to use "send"), be sure to uncomment -the line - -# Vuelogin*authorize: True - -in the file /usr/vue/config/Xconfig, so that the server starts up with -authorization enabled. Also, you may have to reboot the machine in -order to force the server to restart. - ---------------------------------------------- -SCO Unix: ---------------------------------------------- - -Getting Tk to run under SCO Unix: - -Add a "#undef select" to tkEvent.c, and remove the reference to TK_EXCEPTION -around line 460 of main.c. - -Tk uses its own scheme for allocating the border colors for its 3D widgets, -which causes problems when running TK on a system with "PseudoColor" -display class, and a 16-cell colormap. - -If you can't go to eight bitplanes, you can instead start the server with a -"-static" (Xsco) or "-analog" (Xsight) option, making the display class -become "StaticColor". This makes the entire colormap read-only, and it will -return the color that most closely maps to the desired color as possible. - ---------------------------------------------- -Silicon Graphics systems: ---------------------------------------------- - -1. Change the CC variable in the Makefile to: - -CC = cc -xansi -D__STDC__ -signed - -2. Change the LIBS variable in the Makefile to use the X11 shared library - ("-lX11_s" instead of "-lX11"). - -3. Under some versions of IRIX (e.g. 4.0.1) you have to turn off - optimization (e.g. change "-O" in CFLAGS to "-O0" or remove it - entirely) because of faulty code generation. If the Tcl or Tk test - suites fail, turn off optimization. - -4. Add a "-lsun" switch just before "-lm" in the LIBS definition. - Under some versions of IRIX (5.1.1.3?) you'll need to omit the - "-lsun" switch, plus remove the "-lsocket" and "-lnsl" switches - added by the configure script; otherwise you won't be able to - use symbolic host names for the display, only numerical Internet - addresses. - -5. Rumor has it that you'll also need a "-lmalloc" switch in the - LIBS definition. - -6. In IRIX 5.2 you'll have to modify Makefile to fix the following problems: - - The "-c" option is illegal with this version of install, but - the "-F" switch is needed instead. Change this in the "INSTALL =" - definition line. - - The order of file and directory have to be changed in all the - invocations of INSTALL_DATA or INSTALL_PROGRAM. - ---------------------------------------------- -IBM RS/6000's: ---------------------------------------------- -1. To allow ALT- sequences to work on the RS-6000, the following -line should be changed in tkBind.c: - - OLD LINE: - {"Alt", Mod2Mask, 0}, - NEW LINE: - {"Alt", Mod1Mask, 0}, - ---------------------------------------------- -AT&T SVR4: ---------------------------------------------- - -1. The first major hurdle is that SVR4's select() subtly differs -from BSD select. This impacts Tk in two ways, some of the Xlib calls -make use of select() and are inherently broken and Tk itself makes -extensive use of select(). The first problem can't be fixed without -rebuilding one's Xlib, but can be avoided. I intend to submit part -of my work the XFree86 guys so that the next version of XFree86 for -SVR4 will not be broken. Until then, it is necessary to comment out -this section of code from Tk_DoOneEvent() (which is near line 1227): - -#if !defined(SVR4) - void (*oldHandler)(); - - oldHandler = (void (*)()) signal(SIGPIPE, SIG_IGN); - XNoOp(display); - XFlush(display); - (void) signal(SIGPIPE, oldHandler); -#endif /* SVR4 */ - -if you don't comment it out, some scripts cause wish to go into -an infinite loop of sending no-ops to the X server. - -2. As for fixing Tk's calls to select(), I've taken the simple -approach of writing a wrapper for select and then using #define to -replace all calls to select with the wrapper. I chose tkConfig.h -to load the wrapper. So at the very end of tkConfig.h, it now looks -like: - -#if defined(SVR4) -# include "BSDselect.h" -#endif - -#endif /* _TKCONFIG */ - -The file BSDselect.h looks like this: - -#include <sys/types.h> -#include <sys/time.h> -#include <sys/select.h> - -/* This is a fix for the difference between BSD's select() and - * SVR4's select(). SVR4's select() can never return a value larger - * than the total number of file descriptors being checked. So, if - * you select for read and write on one file descriptor, and both - * are true, SVR4 select() will only return 1. BSD select in the - * same situation will return 2. - * - * Additionally, BSD select() on timing out, will zero the masks, - * while SVR4 does not. This is fixed here as well. - * - * Set your tabstops to 4 characters to have this code nicely formatted. - * - * Jerry Whelan, guru@bradley.edu, June 12th, 1993 - */ - - -int -BSDselect(nfds, readfds, writefds, exceptfds, timeout) -int nfds; -fd_set *readfds, *writefds, *exceptfds; -struct timeval *timeout; -{ - int rval, - i; - - rval = select(nfds, readfds, writefds, exceptfds, timeout); - - switch(rval) { - case -1: return(rval); - break; - - case 0: if(readfds != NULL) - FD_ZERO(readfds); - if(writefds != NULL) - FD_ZERO(writefds); - if(exceptfds != NULL) - FD_ZERO(exceptfds); - - return(rval); - break; - - default: for(i=0, rval=0; i < nfds; i++) { - if((readfds != NULL) && FD_ISSET -(i, readfds)) rval++; - if((writefds != NULL) && FD_ISSE -T(i, writefds)) rval++; - if((writefds != NULL) && FD_ISSE -T(i, exceptfds)) rval++; - } - return(rval); - } -/* Should never get here */ -} - ---------------------------------------------- -CDC 4680MP, EP/IX 1.4.3: ---------------------------------------------- - -The installation was done in the System V environment (-systype sysv) -with the BSD extensions available (-I/usr/include/bsd and -lbsd).
