I want to use STL strings in Codewarrior for Palm OS with GapiDraw, but I can't get my project to compile. To make sure nothing in my project was causing the problem, I opened up simple.mcp from the palm samples and added this line to myapplication.cpp.
#include <string>

Below are the errors I got when I tried to compile. I'm using GapiDraw 3.5 Beta 3. If I create a project that doesn't use GapiDraw in Codewarrior, I can use std::string without any problems.

GapiDraw 3.5 beta3 contained the old Palm code and had some issues. Please download the latest RC1 - most of the Palm native code has been completely rewritten.

Ok, it compiles now when I add #include <string> to the minimal example for Palm OS 5, but when I add these lines in ProcessNextFrame,


std::string my_string;
my_string = "My String";


I get this error in the emulator when I launch the program. I'm using the Palm Tungsten C Simulator.
I:\Ripple\ARM\Core\Emul68K\Src\Error68K.c, Line:1543, Write to WindowType (id 65535) off: 20, size: 4


By the way, no message comes up on the splash screen anymore. It's just an empty box.

Ok, ran into a problem with the changes you suggested. I tested this with my project as well as all the samples for Palm OS 5 and I get the same error everytime. Everything runs fine, but when I exit the program I get this error.
MemoryMgr.c, Line:3675, Invalid chunk ptr

By the way, I'm testing this out on the Tungsten C Simulator.
