说在前面
- esp型号：esp32s3
- 开发环境：wsl2
- rustc版本：rustc 1.73.0-nightly
- esp idf版本：v5.1.1
流程
- 目前是按照这个demo的流程可以跑通
- 修改demo中的部分代码，不然可能跑不通

可能的问题
- 以下这些问题奇奇怪怪，主要可能还是
rust toolchain没有安装对 - 还有就是按照rust build中
espup的流程执行之后，我还是继续执行了./install-rust-toolchain.sh，不知道哪里有问题

问题：
cargo-generate缺少pkg-configrun pkg_config fail: Could not run `PKG_CONFIG_ALLOW_SYSTEM_CFLAGS="1" "pkg-config" "--libs" "--cflags" "openssl"` The pkg-config command could not be found. Most likely, you need to install a pkg-config package for your OS. Try `apt install pkg-config`, or `yum install pkg-config`, or `pkg install pkg-config`, or `apk add pkgconfig` depending on your distribution.解决：
apt install pkg-config -
问题：
espflash缺少libudevthread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "`PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=\"1\" PKG_CONFIG_ALLOW_SYSTEM_LIBS=\"1\" \"pkg-config\" \"--libs\" \"-- cflags\" \"libudev\"` did not exit successfully: exit status: 1\nerror: could not find system library 'libudev' required by the 'libudev-sys' crate\n\n--- stderr\nPackage libudev was not found in the pkg-config search path.\n Perhaps you should add the directory containing `libudev.pc'\nto the PKG_CONFIG_PATH environment variable\nNo package 'libudev' found\n"',解决：

- 插件(可选)
这里 - 在初始化的时候由于需要访问到github，这里可以设置下proxy：
- 缺少venv
sudo apt install python3.10-venv
build相关
- 缺少
libclang
解决：主要还是thread 'main' panicked at 'Unable to find libclang: "couldn't find any valid shared libraries matching: ['libclang.so', 'libclang-.so', 'libclang.so.', 'libclang-.so.'], set the LIBCLANG_PATH environment variable to a path where one of these files can be found (invalid: [])"'rust build没有搞好，如果已经搞好了，则需要设置一下环境变量~/rust-build$ . export-esp.sh - 未识别到
xtensa
解决error: unknown target triple 'xtensa', please use -triple or -archrustup update git clone git@github.com:esp-rs/rust-build.git chmod +x install-rust-toolchain.sh ./install-rust-toolchain.sh -i reinstall # this can probably fail the first time, so then softwareupdate --all --install --force ./install-rust-toolchain.sh -i reinstall - 选择target
这里我使用的是$ rustc --print target-list xtensa-esp32-espidf xtensa-esp32-none-elf xtensa-esp32s2-espidf xtensa-esp32s2-none-elf xtensa-esp32s3-espidf xtensa-esp32s3-none-elf xtensa-esp8266-none-elfxtensa-esp32s3-espidf - 每次更改了依赖之后，build都会重下
esp-idf
解决：在首次安装好esp-idf后将IDF_PATH环境变量设置好
同样，也可以将vi ~/.bashrc # 并将下述语句添加到文件最后 下述路径即esp-idf的安装路径 自行更改 export IDF_PATH="/home/le/.espressif/esp-idf/v5.1.1"rust-build里export-esp.sh的LIBCLANG_PATH和PATH加进去

吐槽
也许我打开方式不对，太恶心了，在试错的时候每次build都重新下一遍esp idf，解决方式见上
