【问题描述】：

我正在尝试设置环境为新 PICO 开发一些程序，但在出现此错误后只编译一次：

我正在从 Raspberry SDK 编译它的标准示例的 Blink 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);
    

我已经安装了 VS 代码，并且在为此 PICO 安装了 VS 2019 之后。我一步一步地按照 Raspberry 的文档（开始使用 Raspberry PICO）进行操作。也由 VS2019 的命令提示符启动。

我尝试单独安装最后一个 Windows SDK，我还重新安装了 Visual Studio。但还是一样。

有人可以在这个话题上帮助我吗？这个问题我睡不着:(

提前致谢。 最好的问候

【问题讨论】：

欢迎来到 SO！错误说明：[build] blink\CMakeFiles\blink.dir\compiler_depend.make(4) : fatal error U1033: syntax error : ':' unexpected，所以您的代码中有错字。请包含代码，以便用户查看导致错误的原因。

@fth：不太可能。发生错误的文件是自动生成的，因此不应包含任何语法错误。我会尝试一个干净的构建。

是的，我更新了文件自动生成的内容，感谢您的帮助

没问题@NachFenix

【参考方案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...，

在多次构建后再次出现错误，同样的过程是成功的：D

感谢所有试图帮助我的人，如果知道根问题会很棒！

【参考方案2】：

我自己尝试在 VS Code 中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同样的错误。

错误的原因是包含错误转义路径的 compiler_depend.make 文件。它试图转义 : 在 Windows 驱动器号之后。它不会对每个部分中的第一个条目执行此操作，尽管该条目与每个部分中的第二个条目使用不正确的路径重复。

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

目前我目前的快速修复是在所有 compiler_depend.make 文件中将“\:”替换为“:”

【讨论】：

@NachFenix 我已经找到了根本原因，它似乎是 CMake 3.20.0 的候选版本有问题。我卸载了它并安装了 CMakle 3.19.6，发现 VC 中的初始构建和重建工作 100% 没有错误。文件路径的错误转义不存在。

【参考方案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，适用于那些不太了解它的人。从 build 文件夹运行它。

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

【参考方案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
