Hi John, > Where is the datadir macro defined? The macro should be defined in Makefile, which can be config with `configure --datadir=...`. The default value is "PREFIX/share' You can also try `grep datadir * -nr` to find the keyword in all files. > The .c source files contain #ifdef statements for various "ENABLED" > variables. I can't find these either in the Makefile or conf.h It may be defined in config.h. But it may not be defined if it's not enabled. It can be changed by `configure --enable-...`. You can try `configure -h` to find what things can be enabled. The ENABLE_XXX and HAVE_XXX items are defined in configure.ac Cameron http://www.eguidedog.net - free software for the blind.
