[RESOLVED] "Unresolved external symbol" on Vista 64

[nicolas.sitbon]

I have installed Pelle's C 64 stable version  on vista sp2 64, I compile a simple program without any problem in 32 bits but the same program give me some linkage error when compiled in 64 bits:

Building main.obj.

Done.

Here is my code:

Code: [Select]

int main(void)
{
   return 0;
}

Did you create a new project or did you copy the project

You need to change the library and header search folders for a 64-bit project to the 64-bit ones, if you change an existing project from 32 to 64-bit.

OK, thanks, you're right, I changed an existing 32 bits project to a 64 bits. If I create a new 64 bits project, it works correctly.
My apologize.

[Stefan Pendl]

The latest version v6 allows one to change a 32-bit project into a 64-bit project, you should try that.

Thank you for pointing me that, but I prefer stay on a stable version. I like using software bug free, spending more times using functionnalities instead of tracking bug.

The stable version has also some bugs, so you can choose the unstable version, where errors will be corrected or the stable version, which stay as it is.
