5 [bsp][lpc55sxx] scons 编译不过

发布于 2021-10-20 16:45:16 浏览：1381 订阅该版

进入到
https://github.com/RT-Thread/rt-thread/tree/master/bsp/lpc55sxx/lpc55s69_nxp_evk
目录，然后用scons 编译，编译的时候编译不过，
修改board.h 为如下代码
```
#if defined(__CC_ARM) || defined(__CLANG_ARM)
extern int Image$$ARM_LIB_HEAP$$ZI$$Base;
extern int Image$$ARM_LIB_STACK$$ZI$$Base;
#define HEAP_BEGIN  ((void *)&Image$$ARM_LIB_HEAP$$ZI$$Base)
#define HEAP_END    ((void*)&Image$$ARM_LIB_STACK$$ZI$$Base)
#elif defined(__ICCARM__)
#pragma section="HEAP"
#define HEAP_BEGIN  (__segment_end("HEAP"))
#elif defined(__GNUC__)
extern int __HeapBase;
extern int __HeapLimit;
#define HEAP_BEGIN  ((void *)&__HeapBase)
#define HEAP_END  ((void *)&__HeapLimit)
#endif
```

修改文件bsp\lpc55sxx\Libraries\LPC55S6X\LPC55S6X\gcc\startup_LPC55S69_cm33_core0.S
这里的main改为entry

再编译scons
出现如下log
```

大伙有没有人遇到这个问题？有没有什么好的解决办法？KEIL工程是可以正常运行和使用的。

通过修改rtconfig.py之后，删掉-lc，编译还是出现error
error log如下
