Testing FET with Qt 4.8.0

[Liviu Lalescu]

Could you compile FET with Qt 4.8.0 (released today, 15 Dec. 2011), and report if the compilation and running of FET go well?

I am interested on any platform (GNU/Linux, Windows, Mac OS X).

[Liviu Lalescu]

I just installed Qt 4.8.0 on my GNU/Linux openSuse 12.1, seems OK. The interface is a bit slower when generating (for instance, examples/Brazil/Brazil-more-difficult.fet with starting random seed X=123, Y=123 took in the past ~2 seconds, now takes ~7 - not a very bad thing!, and examples/Germany/secondary-school-1/using_subactivities_constraints/german_subact_constr.fet with the same random seed took ~58 seconds and now takes ~70 seconds).

Could you compare on Windows?

I compiled it on windows 7. pretty fast. the compilation was very smooth

[Liviu Lalescu]

Thank you, but could you run exactly on those two example files and tell me the generation times for official FET-5.16.0 (with Qt 4.7.4) and your compiled FET-5.16.0 (with Qt 4.8.0)? A comparison like I wrote above.

I did the test on my Windows & . core i7 920

The result is:

From FET compiled on QT 4.8.0 with -march=corei7 on gcc 4.6 (minGw)

german_subact_constr = 38-43s

From Official FET:

german_subact_constr = 38-43s


all the same result on both case.

for brazil it took under 1s to get the result

[Liviu Lalescu]

Thank you! So, the interface slowdown is not noticed under Windows.

I will upgrade to Qt 4.8.0 for the next FET version, but I cannot release it right away, because there are not enough changes for the moment.

Please let me know if you notice any Qt bugs for FET with Qt-4.8.0.
