With this commit, SolveSpace gains an Autotools build system and a new
platform-dependent backend implemented using the FLTK GUI toolkit. These
will allow the application to be built and run on Linux and other Unix-like
operating systems, and prospectively, MacOS X.
A number of new files have been added:
* Makefile.am: Automake makefile template; this contains some experimental
support for MinGW and MSVC++ builds that needs further development
* ac-aux/ax_fltk.m4: Autoconf M4 macro to locate and query the system's
installation of FLTK; this will eventually be contributed to the GNU
Autoconf Archive
* autogen.sh: Script to bootstrap the Autotools build system, usually for a
tree just checked out from source control
* configure.ac: Source for the Autoconf configure script; note that this
file specifies a version of 2.1, near the top
* fltk/fltkmain.cpp: Main FLTK backend implementation
* fltk/fltkutil.cpp: Utility functions for the FLTK backend
* fltk/xFl_Gl_Window_Group.{H,cxx}: Implementation of a new
Fl_Gl_Window_Group widget for FLTK, needed to facilitate drawing FLTK
widgets on top of OpenGL graphics as SolveSpace does. This has been
submitted to the FLTK project for (hopefully) eventual upstream
inclusion:
http://www.fltk.org/str.php?L2992
The following minor changes are also a part of this commit:
* Makefile.msvc: Define PACKAGE_VERSION=2.1 for the benefit of
solvespace.cpp in MSVC++ builds
* solvespace.cpp: In the About dialog text, use PACKAGE_VERSION rather than
hard-coding the version of the program
* solvespace.h: Don't define the C99 integer types if
HAVE_C99_INTEGER_TYPES is defined, to facilitate MinGW builds
