BC Copyright (C) 2011 Riad Wahby <email@example.com> <firstname.lastname@example.org> BC is a ballistic calculator for Maemo 5 (Nokia N900). It is written in C and uses code from the GNU Ballistics Library, originally by Derek Yates. This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. See http://www.gnu.org/licenses/gpl-2.0.txt for the full terms of this license. BUILDING You will need the Maemo development environment up and running before you can build this program. For more information on this, see http://maemo.org/development/ Once you have this up and running, cd into the bc directory and simply type "make." For testing inside the dev environment on a PC, use the _X86 arch; for building on the phone, use the _ARMEL arch. BC requires a C compiler that supports nested functions (such as the gcc from the Maemo environment). INSTALLATION To install, you need to copy three files to your phone: bc -> /usr/local/bin bc.desktop -> /usr/share/applications/hildon bc.png -> /usr/share/icons USAGE NOTES A few notes on the meanings of the fields: Sight height is the distance from the sight to the bore center in inches. Sight angle is the angle of the bore relative to the plane perpendicular to gravity. Positive angles are shooting uphill, negative angles are down. Should be in the range -90 to 90. POI at zero range is the distance from the point of aim to the point of impact at the zero range. For example, if you have sighted your rifle 1" high at 100 yards, enter 1 here and 100 in the zero range field.
