在x86_64 Ubuntu下交叉编译iperf-2.0.5到ARM64的配置错误求助

已安装交叉编译器：

sudo apt install gcc make gcc-aarch64-linux-gnu binutils-aarch64-linux-gnu g++-aarch64-linux-gnu

最初执行的配置命令：

./configure --build=aarch64-unknown-linux-gnu --host=x86_64-unknown-linux-gnu --enable-static --disable-shared

得到警告：configure: WARNING: unrecognized options: --enable-static, --disable-shared

执行make时出现编译错误，错误信息如下：

编辑补充：尝试将--host改为aarch64-unknown-linux-gnu，问题依旧，错误完全相同。

1. 修正--build和--host参数 #

交叉编译的参数规则：

• --build：当前编译机器的架构（你的x86_64 Ubuntu）
• --host：目标运行机器的架构（ARM64平台）
  之前的参数完全搞反，这是核心问题。

2. 移除不支持的参数 #

iperf-2.0.5的configure脚本不支持--enable-static和--disable-shared，直接去掉这两个参数即可。

3. 明确指定交叉编译器 #

配置时必须告诉configure使用ARM64的交叉编译器，避免调用本地x86的gcc/g++：

完整配置命令：

./configure --build=x86_64-unknown-linux-gnu --host=aarch64-unknown-linux-gnu CC=aarch64-linux-gnu-gcc CXX=aarch64-linux-gnu-g++

4. 清理旧产物后重新编译 #

先彻底清理之前的错误配置和编译文件：

make distclean

再执行上面的configure命令，最后运行make即可正常编译。

补充：静态编译实现（可选） #

如果需要生成静态链接的iperf，在configure时添加LDFLAGS参数：

./configure --build=x86_64-unknown-linux-gnu --host=aarch64-unknown-linux-gnu CC=aarch64-linux-gnu-gcc CXX=aarch64-linux-gnu-g++ LDFLAGS="-static"
