C语言关于变量定义未使用编译警告warring1.警告warring的产生1.1具体警告warring1.2解决方案1.2.1利用attribute 机制1.2.2利用void关键字2.总结 1.警告warring的产生 在日常写代码的过程中，定义的变量有时候只需要接收某个变量，仅仅对这个变量进行赋值，变量没有进行实际运算操作，这个时候编译器就会有警告。如果是这个原因导致的警告warring，你不处理也不会影响程序的运行。但是当你的工程所有编译的时候，总有几个warring影响你的最终结果，你要是个完美主义

你运行的命令： ```bash grep -r "with-float" ./build_dir/toolchain-aarch64_cortex-a53_gcc-8.4.0_musl-1.2.4_eabi/gcc-8.4.0/ ``` 输出了大量与 `--with-float` 参数相关的信息，这些是 GCC 源码中与浮点配置有关的定义和文档说明。 --- ### 🔍 信息分析 这些文件内容说明了以下几点： - `--with-float=soft`：表示使用软件浮点运算（软浮点）。 - `--with-float=hard`：表示使用硬件浮点运算（硬浮点）。 - 多数架构（如 MIPS、ARM32、PowerPC）支持这个参数。 - 某些架构（如 ARM）中，如果使用 `-mfloat-abi=xxx` 参数，`--with-float` 会被忽略。 - 在 aarch64（ARM64）架构下，`--with-float` **通常不被支持**，因为浮点运算由硬件默认支持。 --- ### ❗关键问题 如果你在构建 OpenWrt/aarch64 工具链时看到类似错误： ``` Valid --with options are: abi cpu arch ``` 这说明你传入了不支持的 `--with-float` 参数，而 aarch64 的 GCC configure 脚本不接受它。 --- ### ✅ 解决方法 #### 1. 查找 OpenWrt 中配置 GCC 的文件： ```bash find . -name "config-*.in" -o -name "Makefile" | xargs grep -l "with-float" ``` 常见路径： - `toolchain/gcc/config-8.4.0.in` - `toolchain/gcc/Makefile` #### 2. 删除或注释掉 `--with-float=xxx` 行： 例如： ```makefile # --with-float=hard ``` #### 3. 清理工具链缓存并重新编译： ```bash make toolchain/clean rm -rf build_dir/toolchain-aarch64_cortex-a53_gcc-8.4.0_musl-1.2.4_eabi/ make toolchain/gcc/initial/compile V=99 ``` --- ### ✅ 额外建议 - 使用 `make menuconfig` 查看是否有浮点相关选项（如 `TOOLCHAIN_FLOAT`）。 - 确保你没有手动在 `target.mk` 或 `toolchain/` 目录下的文件中添加了 `--with-float`。 - 如果你使用的是厂商 SDK（如 Omada、Ubiquiti 等），请检查是否有 SDK 自带的配置启用了该参数。 --- ###
