由于Nmake错误，Raspberry pico无法编译

Question

我正在尝试安装环境来为新PICO开发一些程序，但是在我有了这个错误之后，我只编译了一次：

我正在编译Raspberry SDK中的standart示例的眨眼应用程序：

#include "pico/stdlib.h"

int main() {
    const uint LED_PIN = 25;
    gpio_init(LED_PIN);
    gpio_set_dir(LED_PIN, GPIO_OUT);
    while (true) {
        gpio_put(LED_PIN, 1);
        sleep_ms(250);
        gpio_put(LED_PIN, 0);
        sleep_ms(250);
    }
}

我已经为这个PICO安装了VS代码，安装了VS 2019年之后。我一步一步地从Raspberry (开始使用Raspberry PICO)获得文档。也由命令提示符从VS2019启动。

我已经尝试安装了最后一个Windows，也重新安装了Visual。但还是一样。

有人能在这个话题上帮我吗？这个问题我睡不着：

提前谢谢。诚挚的问候

Answer 1

好的，解决方案是从自动生成的文件中删除内容，保存文件并重新构建.，

在几个构建错误再次出现之后，相同的过程成功了:D

感谢所有努力帮助我，如果知道根本问题将是伟大的！

Answer 2

我自己也遇到了同样的问题，我试图在VS代码中编译，第一遍运行良好，任何重新编译都会因为同样的错误而失败。

错误的原因是包含错误转义路径的compiler_depend.make文件。它正在试图转义:后Windows驱动器的字母。虽然对每个节中的第一个条目没有这样做，但是该条目与不正确的路径重复，作为每个节中的第二个条目。

例如

blink\CMakeFiles\blink.dir\D_\projects\pico\pico-sdk\src\common\pico_sync\critical_section.c.obj: D\:\projects\pico\pico-sdk\src\common\pico_sync\critical_section.c

应该是

blink\CMakeFiles\blink.dir\D_\projects\pico\pico-sdk\src\common\pico_sync\critical_section.c.obj: D:\projects\pico\pico-sdk\src\common\pico_sync\critical_section.c

我目前的快速修复方法是在所有compiler_depend.make文件中将"\:“替换为":”

Answer 3

这里已经提到了一个解决方案(删除/build的内容)，对于那些不太熟悉它的人来说，这是一个重建DOS命令。从build文件夹运行它。

del /q /s * && cmake .. -G "NMake Makefiles" && nmake
