 Posted: Tue Jul 26, 2005 4:09 pm Post subject: Compiling C++ Code |
 |
|
Hi, I'm having some trouble compiling C++ code. I took PSPPets Wifi example, cut out a bunch of the stuff he had in it (Aibo & Clie, Jpeg..). C works just fine and dandy, so I went and renamed all the files to cpp and recompiled. It compiles but I think it fails during linking. Here is (some of) the output:
| Code: |

It just continues on after that with the same type of error except for different functions. I know the functions are basically exported in stubs.s but I dont know how that fits into the big picture.
Any help would be appreciated, thanks. :)

you should try taking a simple project like "me" and adding c++ code to it. i have manage to implement a class into the project, and compiles just fine, but my only problem is when i try to instantiate a new object in the scene. take a look. also by updating your psptoolchain it will get rid of a lot more of the errors. the package i used was in the samples/me/basic/ folder

I've figured out the problem...
Mixing C/C++ isnt very smart. I needed to add wrappers:
| Code: |
#ifndef PSPWIFI_H
#define PSPWIFI_H
#ifdef __cplusplus
extern "C" {
#endif
//code goes here
#ifdef __cplusplus
}
#endif
#endif /* PSPWIFI_H */
|
Now it compies juuuust fine. YEY CLASSES! YEYYY TEMPLATES!!! Wooooottt!!!
I'm going to try and create a socket library with standard berkeley function names... No idea how it would get compiled into a .a though. :-/ |
