Generating code linked with libstdc++ for a target system without OS

["EVANDRO LUIZ HAUENSTEIN" <OP9693 at siemens dot com dot br>]

Hi

 

   Im using g++ (PowerPC version provided by Montavista - ppc_8xx-g++, ppc_8xx-ld, --library stdc++) to generate code for a MPC860 target system.

   The target system is running without OS and I upload the programs (srec format) with a BOOT LOADER via RS232 port.

   The generated code works fine when I do not utilize Dynamic allocation of objects.

 

Static: (works fine)

 

   CBlink MyBlink(500,500);

   MyBlink.BlinkNow();

 

Dynamic: (crashes)

 

   CBlink* pMyBlink;

   pMyBlink = new CBlink(500,500);

   pMyBlink->BlinkNow();

 

   Im not sure why the target crashes... Maybe I have to implement some routines in my target like malloc and etc...

   Anyone tryed to do this?
