# Main binaries
BINDIR=$(PREFIX)/bin
# Some .lua files and ion-* shell scripts
SHAREDIR=$(PREFIX)/share/notion
# Manual pages
MANDIR=$(PREFIX)/share/man
# Some documents
DOCDIR=$(PREFIX)/share/doc/notion
# Nothing at the moment

# Modules
MODULEDIR=$(LIBDIR)/notion/mod
# Compiled Lua source code
LCDIR=$(LIBDIR)/notion/lc
# ion-completefile (does not belong in SHAREDIR being a binary file)
EXTRABINDIR=$(LIBDIR)/notion/bin
# For notion-completeman system-wide cache

# Message catalogs
LOCALEDIR=$(PREFIX)/share/locale

# Configuration .lua files. Overrideable, as config files are usually
# not placed under $(PREFIX).

# PREFIX is unset. No header files are installed at the moment
# though.

# modules through 'libdl' or has non-standard naming conventions.
# You will likely need this option on e.g. Cygwin and Mac OS X.

# On some other systems you may need to explicitly link against libintl.

# macports.

## libc
##

# You may uncomment this if you know that your system C libary provides

# defined, an implementation provided in libtu/sprintf_2.2/ is used.

# monotonic clock. Other systems may not need it, or may not provide a
# monotonic clock at all (which Ion can live with, and usually detect).

# Cygwin needs this. Also when you disable _BSD_SOURCE you may need it.
#DEFINES += -DCF_NO_GETLOADAVG

# If you're using/have gcc, it is unlikely that you need to modify
