Open Source Bullet: DiscoCheck 3.5.1

lucasart · Post by **lucasart** » Sun May 20, 2012 7:28 am

This is a bugfix version of DC 3.5. To all testers: do not waste your time and electricity with DC 3.5, it was a hurried up release and is actually slightly weaker than 3.4. Sorry about that! DC 3.5.1 is the best release so far.

Hi Lucas,
Just curious, did you rename DoubleCheck to DiscoCheck or is it a new engine?

I am quite curious why you say that... Toga 1.4.1SE runs on Windows, Linux, Adroid and MacOSX. So it should be considered fairly portable I think...

I saw a link to the original source code, that was quite ugly portability-wise.

Do you have a link to the latest/bestest open source & portable version of Toga ?

Does this mean FruitFly might finally get a place on the OSB?

I can give you the source if you want (and this version should be stronger, much stronger).

Here are my Toga ports

http://hardy.uhasselt.be/Toga/posix_versions/

This version of 1.4.1SE is included in Debian/Ubuntu.

OK. Just send me a link and I'll test it. However I will play a few bullet games against Fruit 2.1 before to have an idea of its relative strength, if only to have a good choice of opponents.

Unfortunately: the executable don't work for me (SSE4 instructions?) nor any of the makefile. They all end up that way

Lucas,

FF link will be on its way shortly.

T2: Not SSE4. floor() is a <cmath> function so requires -lm. pthread_join() and pthread_create() are <pthread.h> functions so rquires -lpthread and probably -pthread. dl_close(), dl_open() and dl_sym() are <dl.h> functions, and will probably (this depends on system) require -ldl.

So the Toga Makefile appears to be missing libraries, as it seems to be happening in the link stage.

Correct!

Sorry that the makefiles did not work. This is quite weird. I probably used something like

g++ *.cpp -O2 -ldl -lpthread -lm -otoga

to compile (this was several years ago).
