新手求助：关于配置RT_USING_HEAP

发布于 2012-12-04 22:32:26 浏览：5761 订阅该版

我使用1.1.0 RC版本对STM32F10X裁剪时，发现如果定义“RT_USING_HEAP”，编译时会出现下面的错误：
.obj
tthread-stm32.axf: Error: L6218E: Undefined symbol rt_system_heap_init (referred from startup.o).
.obj
tthread-stm32.axf: Error: L6218E: Undefined symbol rt_free (referred from idle.o).
.obj
tthread-stm32.axf: Error: L6218E: Undefined symbol rt_malloc (referred from ipc.o).

如果将RT_USING_HEAP注释掉，则不会出现上面的三个错误。由于要经常使用RT_USING_HEAP，恳请各位高手帮忙解决这个问题。多谢！
顺便将我出错的rtconfig.h也粘上来：
