What were you trying to do?
build a full set of Qt 4.3.3 libraries, executables and examples
(both static and dynamic, though this locker contains only the
dynamic versions- static version had same problem) using Athena 9.4
default gcc/g++.
What's wrong:
the build (on a 745 Dell) completes without error, though I did see
some warnings about "libGL.so.1 may be incompatible with
libGL.so.1.2..." flash past as the build progressed - I didn't save
the output.
when everything is finished, attempting to run any OpenGL-dependent
binary on a 745 Dell (such as "qtdemo" in the top-level bin directory
or any of the examples in the examples/opengl directory) segfaults.
yet running the same binaries on one of the HP-Compaq machines works,
although it complains "can't find libGL.so.1.2" unless I put
/usr/X11R6/lib on LD_LIBRARY_PATH.
if I recompile everything on an HP-Compaq, the binaries
work correctly on both platforms.
Qt is very well supported by the developers. I seriously doubt that
it's a problem with their software or build system.
What should have happened:
[Please replace this line with your information.]
Please describe any relevant documentation references:
I discussed this with jdreed who suggests that the ATI drivers on the
745s may be causing this.
To reproduce: build a dynamic set of libs/binaries/demos from
qt-x11-opensource-src-4.3.3.tar.gz (I can supply this if necessary though
it's easy to find on the TrollTech download sites).
I used the following commands to build/install:
configure -platform linux-g++ -qt-gif -release -prefix <desired tree root>
make
make install
