# You must replace "gdb" and "GDB" with the lower case name and
# upper case name of your new package.  Some places below will say
# "Do not change this" - that does not include this global change,
# which must always be done to ensure we have unique names.

#
# GDB_VERSION, GDB_SITE and GDB_SOURCE define
# the upstream location of the source code for the package.
# GDB_DIR is the directory which is created when the source
# archive is unpacked.
# GDB_UNZIP is the command used to unzip the source.
# It is usually "zcat" (for .gz) or "bzcat" (for .bz2)
#
# You should change all these variables to suit your package.

# can correctly detect the presence of ncurses while the actual compilation
# doesn't find the ncurses.h header file. Workaround is to disable TUI.
