+For your convenience (and with the author's permission) a copy of the
+MetaKit source is bundled with SimGear in $(top_srcdir)/src-libs/.
+You must have metakit installed before you can build SimGear.
+
+- Most linux distributions have a metakit package. For linux
+ developers, we recommend ysou install your distributions package
+ rather than building from source.
+
+- For developers on most other platforms, you will have to build
+ metakit from source and install it yourself. For your convenience a
+ tar ball of the metakit source is included with the simgear source
+ distribution. Untar the metakit source, and follow the included
+ build and installation instructions.
+
+Once metakit is installed you can return to configuring and building
+Simgear.
+
+=============================================================================
+
+Potentially important build note:
+
+ Later on when you are linking programs with -lmk4 (i.e. FlightGear or one
+ of it's associated programs) if you come across an error similar to the
+ following:
+
+ c++ -Wall -O2 -L/usr/local/lib -o gensimple gensimple.o libAirports.a
+ -lsgdebug -lsgmisc -lmk4 -lz -lm
+ /usr/local/lib/libmk4.a(view.o)(.text+0x1c8):view.cpp: multiple definition
+ of `c4_View::~c4_View(void)'
+ libAirports.a(simple.o)(.text$_$_7c4_View+0x0):simple.cxx: first defined
+ here
+ collect2: ld returned 1 exit status
+ make[2]: *** [gensimple] Error 1
+ make[2]: Leaving directory `/home/curt/FlightGear-0.7.7/src/Airports'
+ make[1]: *** [all-recursive] Error 1
+ make[1]: Leaving directory `/home/curt/FlightGear-0.7.7/src'
+ make: *** [all-recursive] Error 1
+
+ Then you need to come back and rebuild Metakit with the -DNDEBUG flag.
+ For unix/cygwin systems, modify the unix/Makefile file and add -DNDEBUG
+ to the CFLAGS line.
+
+Now we return you to the official metakit readme ... :-)
