Using the new configure, the configure script is no longer able to find my Xaw3d headers because it only looks in X11/Xaw for ThreeD.h which is in X11/Xaw3d instead. What is the correct way to tell configure to search for ThreeD.h where it lives? I have the xorg X11 and installed Xaw3d on my own, but without changing any of its default directories. This is for 21.5.b20 Here is a snippet from the config.log | /* end confdefs.h. */ | #include <X11/Xaw/ThreeD.h> configure:23448: result: no configure:23483: checking for X11/Xaw/ThreeD.h configure:23490: result: no configure:23508: checking X11/Xaw/XawInit.h usability configure:23520: gcc -c -w -g -Os -I/usr/X11R6/include conftest.c >&5 In file included from conftest.c:134: /usr/X11R6/include/X11/Xaw/XawInit.h:51: error: parse error before "XawOpenApplication" /usr/X11R6/include/X11/Xaw/XawInit.h:52: error: parse error before '*' token configure:23526: $? = 1 -- Dr. Robert Delius Royar Associate Professor of English Morehead State University Morehead, Kentucky
