Visual studio code 由于Nmake错误，Raspberry pico无法编译

我正在尝试setup Enviroment为新的PICO开发一些程序，但在出现以下错误后只编译了一次：

我正在编译的blink应用程序是Raspberry SDK的标准示例：

#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，并在安装VS 2019之后安装了VS代码。我循序渐进地阅读了Raspberry的文档（Raspberry PICO入门）。也由VS2019的命令提示符启动

我尝试单独安装上一个Windows SDK，也重新安装了Visual Studio。但还是一样

有人能在这个话题上帮我吗？我无法解决这个问题：(

自动生成的文件问题所在示例：

致以最诚挚的问候

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

在多次构建之后，错误再次出现，并且相同的过程成功：D

---

感谢所有试图帮助我的人，如果知道根问题会很好！

我自己在尝试用VS代码编译时也遇到了同样的问题，第一次编译很好，任何重新编译失败都会出现同样的错误

错误的原因是编译器_depend.make文件包含错误的转义路径。它正在尝试转义Windows驱动器号后的：。虽然每个节中的第一个条目都使用错误路径作为每个节中的第二个条目进行复制，但它不会这样做

比如说

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

---

到目前为止，我目前的快速修复方法是将“\：”替换为“：”在所有编译器dependent.make文件中
