Why my program can't run under debian/Linux?

Dear all:

My program can run under debian/Linux by build progam CONFIG=Debug,
but it can build when CONFIG=Release, but it can not run, it still sop in this line:


please help me!

Does the demo app run ok? If it does, then you’re probably doing something dodgy in your own code… And if the demo doesn’t run, then have you tried the latest juce version from GIT?

Dear jules:

i get the latest juce demo from GIT, and build them by CONFIG=Release , then it can not run too, and stop this too < src/core/juce_Atomoc.h:Line258 >

all can run under Debug Mode, but can not run under Release!!!

can you give me some help?

Well, it works just fine for me (in ubuntu)…

HAve you got the latest gcc? The atomics are generated by the compiler, so maybe you’re hitting a compiler bug…

src/core/juce_Atomoc.h:Line258: while (! compareAndSetBool (newValue, currentVal)) { currentVal = value; }

in this line, the run for ever, i use the latest gcc in debian/linux. compareAndSetBool always return false.

i come from China, my english is very poor, sorry.

Well, that’s a complete mystery… What else is on the call stack?

your latest demo app have same problem, so i think this is a bug, but i have no idea to solve this.
i need your help, thank you!

Yeah, I’d like to help you - that why I asked what was on the call stack? Have you tried debugging it? Since I can’t reproduce it, you’ll need to provide some more helpful information!

same here, the jucedemo in release mode hangs when starting:

any hints ?

ok, Dear jules, thank you very much!

same as you say, i haove debuged the demo app project, and discovery it stop at :

src/core/juce_Atomoc.h:Line258: while (! compareAndSetBool (newValue, currentVal)) { currentVal = value; }

int the while, compareAndSetBool (newValue, currentVal) always return false, the while execute for ever, so the jucedemo will hangs when starting like kraken say.

do you need any other help?
i use the latest Debian/Linux5.07, and use the latest gcc by apt-get.

Dear jules, kraken:

i find a not good method to solved this problem, it a temporary method.

in Release mode, set to “No optimistation” .just do this, the app can run normal.

i hope you can find better method to solved this!!!


It’s certainly a compiler problem - the code is perfectly ok and works for me with gcc 4.4.3 (and also gcc4.2 on the mac of course). Maybe try upgrading to 4.4.3…?
