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.
