!!!IMPORTANT ADDENDUM FOR FlightGear 0.48 and UP!!!
For those using Cygwin32 to build from source on win95/NT ... I've
run into a show stopping bug with the cygnus compiler where it can't
compile legit C++ code that includes the string class as a part of a
structure built from the STL. Fortunately, EGCS fixes this and many
other problems with the cygwin32 compiler. If you are a cygwin32 user
and want to be able to compile FG 0.48 you will have to upgrade your
Cygnus installation from beta 19 to beta 19.1, and overlay the EGCS
update over top of the Cygnus installation.
If anyone is interested I can send them a small test program that
exercises this bug in the cygwin32 compiler, but passes with flying
colors through EGCS.
The Cygwin32 beta 19.1 upgrade is available from:
ftp://ftp.cygnus.com/pub/gnu-win32/latest/b19.1-update/
Make sure to follow the directions you find there (it's less than
200Kb to download.)
The EGCS upgrade is available from:
http://www.xraylith.wisc.edu/~khan/software/gnu-win32/egcs.html
Again, make sure you follow the directions. (This is several
megabytes to download.) It is recommended that you unroll the egcs
stuff over top of your cygwin32 installation. It will replace many of
the files. I did this today and if you carefully follow the
directions you shouldn't have any trouble. :-)
Note: you don't have to wait for FG 0.48 to be released to upgrade to
EGCS, it should build earlier versions of FG just fine. I hope
... :-) I've gone through the process once myself, so I guess that
makes me the expert. Feel free to forward questions to me at:
