 Posted: Fri Oct 21, 2005 5:53 pm Post subject: C++ class make the psp turn off |
 |
|
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 Is my toolchain out of date or other issues make this error?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~ |

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". |

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

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. |

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.

| 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.)
