I want to debug program about mbed, I export a program from mbed wed. it is successful running from web, the code is

1.#include "mbed.h"

Read temperature from LM75BD 2.Serial pc(USBTX, USBRX); tx, rx DigitalOut myled(LED1); I2C i2c(p28, p27);

int addr = 0xde; int j=0; int main() { char cmd[2]; cmd[0] = 0x00; cmd[1] = 0x80; i2c.write(addr, cmd, 2); i2c.start(); i2c.write(addr); i2c.write(00); i2c.write(0x00); i2c.stop(); wait(0.5);

cmd[0] = 0x00;

while(1){ i2c.write(addr, cmd, 1); addr=0xdf; i2c.start(); myled=1; j=i2c.write(0xdf); j=i2c.write(0x00); cmd[0]=i2c.read(0); i2c.stop(); pc.printf("%.2x\b\b",cmd[0]&0x7f); wait(0.1); } } but when I export form web,open with keil ,but there are error at first line it is" error :in include chain (stdlib.h):declaration of "atexit" has a different language linkage."

Hello Albert zhang,

what is your version of KEIL?

posted by Martin Kojtal 11 Sep 2013

Ok, well I used the free version and got the same error.

I tracked it down to the stdlib.h file, the declaration of 'atexit' is preceded by the line 'extern "C++"', which when commented out, removes the error, but I assume just shifts the problem to something else.

I think Keil doesn't like using C++ code in a C file or something along those lines.
