c - STM32F4编译Makefile报错

Question

我对 Makefile 还是很陌生，所以我在这方面遇到了一些麻烦。我正在尝试为 STM32F4 编译一些代码，我为 STM32F3 获取了这个 Makefile.common 并且只是更改了工具链和目录以反射(reflect)我将用于我的开发的那些。不幸的是，我遇到了这个编译错误，虽然我已经尝试广泛地使用谷歌搜索它，但没有什么能帮助我解决它。

这是我遇到的错误

make: execvp: /home/wilfred/CodeSourcery/Sourcery_CodeBench_Lite_for_ARM_GNU_Linux/bin: Permission denied make: * [startup_stm32f4xx.o] Error 127

这是我的 Makefile.common 的代码。谢谢!

您可以使用 chmod 更改权限(运行“man chmod”以获取更多信息)。

例如，

chmod 777 我的文件.c

更改 myfile.c 以拥有所有用户的所有权限 (rwx)。
