I'm trying to get FlightGear compiled in Windows so that I can make some modifications and customizations. Anyway, when I try to compile the SimGear component, VisualStudio returns errors saying that the mklib.dsp and zlib.dsp files are invalid. If I ignore these messages and try to compile anyway, it returns zlib.h is not found. How do I install this zlib library? I also expect to encounter the same problem with mklib once the zlib thing is fixed. Any help is appreciated.Thanks,Drew

I'm not a programmer, but I think you can get zlib and its related source code from http://www.zlib.net/As for mklib, I'm not sure. It seems to be one of the libraries in Mesa (http://mesa3d.sourceforge.net/) but Windows shouldn't need that (Mesa). Did you get the source code for plib as told by http://flightgear.org/Docs/InstallGuide/ge...tml#x6-160002.4 ?

I have plib, and it compiled easily...that hasn't been a problem at all. There was zlib source zipped up in the simgear package, but there were no VisualStudio compatible configuration files. I've never programmed in Windows, so I'm completely lost as far as how to configure things using VisualStudio...the rest of the packages compiled very easily since the appropriate project files were already there.I'm much more comfortable with Linux, but what I'm doing now with FlightGear requires that I work in a Windows environment.Drew

Use Cygwin. You can read more by going here: http://www.flightgear.org/Docs/InstallGuide/getstartch2.html

I need to use Visual Studio...I'm working in an office that uses it, and I can't exactly go off on my own with this.I'm about to give up on FlightGear. I finally got all of the libraries and headers set up properly (including zlib), and now I have thousands of "unresolved external symbol" errors that I have no clue how to fix. This source is a complete mess, and if I'm having this much trouble now, I imagine it'll continue to be a big struggle to make changes.Any Windows developers out there? Anyone? Bueller?Drew

I was going to suggest you to seek help from the developers, but I see you have turn to them already.I hope I could have helped you further on this. Unfortunately, I am not a programmer. My only suggestion to you is same as before: use cygwin. http://www.cygwin.com/
