INCLUDE FILES and LIBRARY LOCATIONS

The X11 R5 and Motif 1.2 widgets are online on all platforms. The include files and libraries for the Motif 1.2 widgets, libXv, and X11 R5 are located in these subdirectories:
/usr/include/Motif1.2
/usr/include/X11R5
/usr/lib/Motif1.2
/usr/lib/X11R5

COMPILING

You must explicitly specify the proper paths to access X11 R5 and the Motif 1.2 widgets.

Use this compiler command if you want Motif1.2 widgets and X11 R5.

cc -I/usr/include/Motif1.2 -I/usr/include/X11R5 -o<file> <file.c> -L/usr/lib/Motif1.2 -L/usr/lib/X11R5

Note: above command is all on one line.

To save typing, you can either incorporate the above into a Makefile, or add these options into the environment variable CCOPTS. You will also need to "link in" the libraries for X11 with -l options.

NOTE: When compiling things with X11/Motif libraries, the following error message might happen (and be mentioned several times):

<Include file name>: ###: too much defining - use -H option

The C Preprocessor only allocates a certain amount of space for #define statements. You must tell the C Preprocessor to allocate more room for #define statements. You do this by adding the following into your 'cc' options (either on the command line or in the makefile):

-Wp,-H200000

This will tell the C compiler to tell the C Preprocessor to allocate room for 200,000 #define statements. You may have to adjust this number accordingly. More info can be obtained by seeing the man pages for 'cpp'.

Note: The MIT Athena Toolkit Widgets libraries and header files are also on the system. They are located in a different directory path of the system then the above libraries.

Location of Athena Widgets library files:
/LINKS/contrib/lib/X11
Location of Athena Widgets header files:
/LINKS/contrib/include/X11

NOTE THAT THESE ARE NOT SUPPORTED - USE AT YOUR OWN RISK!

Note: Use the "find" command starting at /usr to locate the exact path of any specific file.

e.g. find /usr -name Xm.h -print

(this will locate the path for Xm.h)
