C++ class make the psp turn off

[laichung]

If found that when I use class in my project, even my file can compile , when it run at the psp , psp will stop response and then turn.

for example , I cant call this : testclass * tc = new testclass();

what's going on ? Is my toolchain out of date or other issues make this error?

Thanks all of your help~

hi,

I'm a newbee in psp dev, but my c++ code run fine on my psp. Can you give me more informations about your code/makefile ?

I also use C++ in PSPRadio and it works fine.. Are you compiling against libc or newlib? Try updating the toolchain/sdk...

actually my code is really normal as a c++ project;
I only define a test class , and try to init it by using "new" operator

and compiler option should not affect the result since "new" operator is just allocate memory for the class. that's mean I cant use "memalloc" too.

may be the problem is due to out date of my toolchain, I will try to update it.

No, the new operator calls the constructor, too, which could crash and all constructors of objects you've declared as member variables, like "std::string m_name".

but my class is just like this

Code: Select all

class testclass{
public:
	char *testc;
};

really simple but create error , even I have updated my toolchain.

I think the problem of mine sdk is , malloc is not work , and I dont know why:

Code: Select all

	int *ptr = (int *)malloc(sizeof(int) * 10);

Even this simple code will turn off my psp. Any one know what's going on? Big thanks.

Where is the constructor of your class ?

Are you on firmware 2.0?

Up until the latest EBOOT loader, malloc was broken. It's working fine in loader v0.7, so you should upate if you're on 2.0.

[laichung]

constructor is not a must for class.

ANd finally I solve the problem by changing the order of the libraries inculded in the makefile.

thanks all

Ok, i always write a constructor to initialize some variables into my classes.
We learn all days ;)

Are you sure its the class that is turning it off? You could have another error.

The problem is cause by , when it call malloc function , psp will turn off.
I dont know what the order of the library will make this error. (May be the program reference to a wrong function.)
