由于 Nmake 错误，Raspberry pico 无法编译

Question

我正在尝试设置环境来为新的 PICO 开发一些程序，但只编译了一次，就出现了这个错误：

我正在编译的 Blink 应用程序是来自 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);
    }
}

我已经安装了 VS 代码，并在为此 PICO 安装了 VS 2019 之后。我一步一步地遵循了 Raspberry 的文档（开始使用 Raspberry PICO）。也由 VS2019 的命令提示符启动。

我试过单独安装最后一个 Windows SDK，我也重新安装了 Visual Studio。但还是一样。

有人可以帮我解决这个问题吗？这个问题我睡不着:(

提前致谢。最好的问候

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...，

几次构建错误再次出现，同样的程序成功了:D

感谢所有试图帮助我的人，如果知道根问题就太好了！

Answer 2

我自己在 VS Code 中尝试编译时遇到了同样的问题，第一遍工作正常，任何重新编译都失败并出现相同的错误。

错误的原因是 compiler_depend.make 文件包含不正确的转义路径。它试图在 Windows 驱动器号之后转义 : 。它不会对每个部分中的第一个条目执行此操作，尽管该条目与不正确的路径一起复制为每个部分中的第二个条目。

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

我目前的快速修复是将所有 compiler_depend.make 文件中的“\:”替换为“:”

Answer 3

这是已经提到的解决方案（删除 /build 的内容）作为重建 DOS 命令，供那些不太熟悉它的人使用。运行它来自构建文件夹。

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

Answer 4

卸载当前的 CMAKE 版本并从这里安装 3.20 版本： https://cmake.org/files/v3.20/

不要忘记将 CMAKE 添加到路径

由于 Nmake 错误，Raspberry pico 无法编译
