Question

过去几天我一直试图在 Linux 上使用Eclipse设置GNU ARM插件。问题是我无法为我的STM32 Discovery F4板正确编译。编译普通的gcc ARM项目没有问题，但是当谈到STM32F4xx时，我遇到了这些错误：

我的代码是默认导致闪烁的一个：

// STM32F4 led blink sample (trace via ITM).
//
// In debug configurations, demonstrate how to print a greeting message
// on the trace device. In release configurations the message is
// simply discarded.
//
// To demonstrate POSIX retargetting, reroute the STDOUT and STDERR to the
// trace device and display messages on both of them.
//
// Then demonstrates how to blink a led with 1Hz, using a
// continuous loop and SysTick delays.
//
// On DEBUG, the uptime in seconds is also displayed on the trace device.
//
// Trace support is enabled by adding the TRACE macro definition.
// By default the trace messages are forwarded to the ITM output,
// but can be rerouted to any device or completely suppressed, by
// changing the definitions required in system/src/diag/trace_impl.c
// (currently OS_USE_TRACE_ITM, OS_USE_TRACE_SEMIHOSTING_DEBUG/_STDOUT).
//

// ----- Timing definitions -------------------------------------------------

// Keep the LED on for 2/3 of a second.

main(int argc, char* argv[])

  // By customising __initialize_args() it is possible to pass arguments,
  // for example when running tests with semihosting you can pass various
  // options to the test.
  // trace_dump_args(argc, argv);

  // Send a greeting to the trace device (skipped on Release).
  trace_puts("Hello ARM World!");

  // The standard output and the standard error should be forwarded to
  // the trace device. For this to work, a redirection in _write.c is
  // required.
  puts("Standard output message.");
  fprintf(stderr, "Standard error message.\n");

  // At this stage the system clock should have already been configured
  // at high speed.
  trace_printf("System clock: %uHz\n", SystemCoreClock);

  timer_start();

  blink_led_init();

  uint32_t seconds = 0;

  // Infinite loop
  while (1)
    {
      blink_led_on();
      timer_sleep(BLINK_ON_TICKS);

      blink_led_off();
      timer_sleep(BLINK_OFF_TICKS);

      ++seconds;

      // Count seconds on the trace device.
      trace_printf("Second %u\n", seconds);
    }
  // Infinite loop, never return.
}

#pragma GCC diagnostic pop

我尝试将cstdlib文件添加到项目中，但后来又出现了新的错误。谢谢你的帮助！
