nanogui: Thread: does flnx work when built with recent libs and compiler?

Hi all,

I've been succesfully using flnx for ages, and have just rebuilt it, and
microwindows (to run under X) on a red hat 7.1 box to do a bit of
testing. Upon cranking up my application, i found that i did not
display, and neither do any of the apps in the test/ directory under
flnx - the microwindows demo apps run fine. By 'not display', I mean
that inside the microwindows box, all the widgets were correctly drawn
(i can click on buttons and the right stuff happens as a result), but
everything was black. 

I gather that flnx came from a time when there was no such thing as a
C++ standard, and it has some odd code as a result - I had to remove the
definitions of pubseekoff() and pubseekpos() in streambuf.h in order to
get flnx to build. So, I was wondering whether maybe the newer C++
libraries or something may cause problems...

The red hat 7.1 box has libc-2.2.2 libstdc++-libc6.2-2.3 and g++/gcc
2.96, and  my usual development platforms (arm and x86) have libc 2.1.3,
libstdc++-6.1.
-2.3 and g++/gcc 2.95.3 . I'm using flnx 0.15 and microwindows-0.89-pre6
. Has anyone got flnx and microwindows built and running on such a
platform? Does anyone have any ideas what could be wrong?

You are using a very old version of FLNX that has issues with g++-2.96.  
Basically, there is an uninitalized variable that gets assigned differently 
than with prior versions of the compiler.

We have also made changes to help make FLNX more ANSI compatible.  The latest 
tarball on the website should work, or you can grab the latest version from 
CVS.
