Hi First: In the welcome email the page http://www.xemacs.org/beta/ is mentioned, but it claims: ! What's New? ! * XEmacs 20.5 beta27 (Kinder) is released. See the latest Release Notes ! for further details. ! * XEmacs 20.4 (Emerald) is released. See the latest Release Notes for ! further details. which looks rather odd. Back to 21.2.33; using ./configure I get: ---------<cut>------------------------------------ X11 compilation variables: x_libraries = '/usr/X11R6/lib' x_includes = '/usr/X11/include' X_CFLAGS = ' -I/usr/X11/include' X_LIBS = ' -L/usr/X11R6/lib' X_PRE_LIBS = ' -lSM -lICE' X_EXTRA_LIBS = '' Defining BITMAPDIR = "/usr/X11/include/X11/bitmaps:/usr/X11/include/bitmaps" checking for X defines extracted by xmkmf Defining NARROWPROTO Defining linux Defining __i386__ Defining _POSIX_SOURCE Defining _XOPEN_SOURCE Defining _BSD_SOURCE Defining _SVID_SOURCE checking for X11/Intrinsic.h... no configure: error: Unable to find X11 header files. ---------<cut>------------------------------------ But I have: ls -l /usr/X11/include/X11/Intrinsic.h -r--r--r-- 1 root root 73581 Mar 16 19:32 /usr/X11/include/X11/Intrinsic.h What can go wrong? This is a SuSE Linux System 6.4/i386 with XFree86 4.0 Tobias PS: I yesterday I tried it using --x-includes but with the same result.
