Re: [Flightgear-devel] Trouble compiling: undefined reference to ssgCullAndDraw(ssgRoot*)
Curt, Thanks for the suggestion - actually I figured it out just yesterday. I switched back to the non-cvs plib tgz file (v. 1.6.0) and it worked fine. And yes, I had used the same compiler for all of the code. The function definitions in the cvs version of plib and in the 1.6.0 tarball do not match up. Compare: in plib-cvs/src/ssg: [EMAIL PROTECTED] ssg]$ grep CullAndDraw * Binary file libplibssg.a matches ssg.cxx:void ssgCullAndDraw ( ssgBranch *r ) ssg.h:void ssgCullAndDraw ( ssgBranch *root ) ; in plib-1.6.0/src/ssg [EMAIL PROTECTED] ssg]$ grep CullAndDraw * Binary file libplibssg.a matches ssg.cxx:void ssgCullAndDraw ( ssgRoot *r ) ssg.h:void ssgCullAndDraw ( ssgRoot *root ) ; I'm not experienced enough to know, maybe this is just something that my compiler should be overlooking. Take care, John John, Have you compiled plib with the same compiler as the rest of the code? Curt. John A.

[Flightgear-devel] Does SGRoute.distance_off_route() work?
Hello everyone- I was just wondering if the subroutine SGRoute.distance_off_route() calculates accurate results (or even reasonably usable results for navigation in fgfs) for waypoints on a wgs84 system. I've run some tests and it seems okay, but I'm no expert - can someone verify this? Also, what units does it return? I measured two distances, two line segments a and b, forming one line perpendicular to line c, and the total distance came to be .03802. Then I used the SGWaypoint routines to calculate the actual length of line a+b and got 1.92609NM or 3567.11 meters. This makes me suspect that either distance_off_route() is using some strange (large) units, or else it just isn't working correctly. The code says that it assumes that all points are lying on a flat plane, and that it works best with a cartesian system. Thanks, John Gallas __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
