GLUT or SDL exception support?

crosstalk · 12-28-2010, 02:35 PM

I have just finished installing FlightGear on my ~amd64 Gentoo machine (FlightGear and SimGear were manually installed for development work), and when I ran it, I got this message:

Code:

Uncaught Exception: you should see a meaningful error message
here, but your GLUT (or SDL) library was apparently compiled
and/or linked without exception support. Please complain to
its provider!

I looked at the USE flags for GLUT and SDL, and enabled GLUT's debug use flag (then reconfigured and recompiled FlightGear and SimGear). However, this message still persists.

emerge -pv freeglut libsdl:

Code:

[ebuild   R   ] media-libs/freeglut-2.6.0  USE="debug -mpx" 0 kB
[ebuild   R   ] media-libs/libsdl-1.2.14-r4  USE="X alsa audio joystick opengl video -aalib -custom-cflags -dga -directfb -fbcon -ggi -libcaca -nas -oss (-ps3) -pulseaudio -static-libs (-svga) -tslib -xinerama -xv" 0 kB

My configure lines for SimGear and Flightgear:

Code:

CFLAGS="-O0 -pipe -march=athlon64 -ggdb" CXXFLAGS="$CFLAGS" ./configure --prefix=/home/<user>/flightgear/sginstall
CFLAGS="-O0 -pipe -march=athlon64 -ggdb" CXXFLAGS="$CFLAGS" ./configure --prefix=/home/<user>/flightgear/fgfs --with-simgear=/home/<user>/flightgear/sginstall/

How do I enable exceptions support in SDL and GLUT?

Thank you for any help.

Hello,

I think that just adding: "-fexceptions" to your CXXFLAGS should fix the the problem.

Best regards

That seems like it would work (thank you for trying to help).

I tried it -- it didn't work. I did it for all of FlightGear's dependencies, as well as FlightGear itself. I'm still getting the same message.

Any other ideas? (I'll keep looking myself, too).
