Helpful Hints for R4 1. You are building servers on 680x0 or VAX platforms, you should use GCC. 2. Due to minor bugs in the configuration control, if you are trying to install library files into a directory other than /usr/lib/X11, you'll need to set XFILESEARCHPATHDEFAULT and ERRORDB in mit/config/site.def: #ifndef XFILESEARCHPATHDEFAULT #define XFILESEARCHPATHDEFAULT "/usr/local/lib/X11/%L/%T/%N%S:/usr/local/lib/X11/%l/%T/%N%S:/usr/local/lib/X11/%T/%N%S" #endif #ifndef ERRORDB #define ERRORDB "/usr/local/lib/X11/XtErrorDB" #endif and you'll need to patch line 54 of mit/clients/twm/parse.c #define SYSTEM_INIT_FILE "/usr/local/lib/X11/twm/system.twmrc" 3. Do not turn on InstallXdmConfig as there is no longer a default directory under mit/clients/xdm/config/. 4. Some versions of tcsh erroneously set the eighth bit on characters they emit. If you are not seeing text in your xterm windows and are using tcsh, try using a different shell (e.g. xterm -e /bin/sh). 5. Sites running BSD 4.3 on vaxes will need to enable the qvss and/or qdss servers and will need to specify -DX11R4 in the ServerDefines line in mit/config/bsd.cf: #ifdef VaxArchitecture #define XqvssServer Xqvss #define XqdssServer Xqdss #define ServerDefines StandardDefines ExtensionDefines -DXDMCP -DNOSTDHDRS -DX11R4 #endif
