CentOS7(arm64)编译HAProxy2.2时找不到-latomic的解决求助

编译HAProxy时执行命令：

make TARGET=linux-glibc USE_PCRE=1 USE_PCRE_JIT=1 USE_OPENSSL=1 USE_ZLIB=1 USE_LINUX_TPROXY=1 USE_REGPARM=1 USE_LUA=1 USE_THREAD=1 USE_TFO=1

出现错误：

CC      src/version.o
LD      haproxy
/usr/bin/ld: cannot find -latomic
collect2: error: ld returned 1 exit status

链接器详细日志：

attempt to open //usr/aarch64-redhat-linux/lib64/libatomic.so failed
attempt to open //usr/aarch64-redhat-linux/lib64/libatomic.a failed

已尝试的操作：

• 创建软链接：

  ln -s /usr/lib64/libatomic.so.1.2.0 /usr/lib/libatomic.so
  

• 安装devtoolset-7-libatomic-devel库：

  yum install centos-release-scl-rh
  yum install devtoolset-7-libatomic-devel
  

1. 创建正确的软链接到链接器搜索路径 #

先确认系统中libatomic文件的位置：

find / -name "libatomic*"

如果找到/usr/lib64/libatomic.so.1.2.0，直接在链接器搜索的/usr/lib64目录下创建软链接：

ln -s /usr/lib64/libatomic.so.1.2.0 /usr/lib64/libatomic.so

2. 启用devtoolset-7环境变量 #

安装devtoolset-7后，必须先加载对应的环境，否则编译时不会使用该工具链的库：

source /opt/rh/devtoolset-7/enable

加载完成后重新执行HAProxy的编译命令。

3. 编译时手动指定库路径 #

若上述方法无效，可在编译命令中通过LDFLAGS强制指定libatomic的路径：

make TARGET=linux-glibc USE_PCRE=1 USE_PCRE_JIT=1 USE_OPENSSL=1 USE_ZLIB=1 USE_LINUX_TPROXY=1 USE_REGPARM=1 USE_LUA=1 USE_THREAD=1 USE_TFO=1 LDFLAGS="-L/usr/lib64 -latomic"

4. 安装系统原生libatomic开发包 #

尝试安装CentOS7 arm64原生的libatomic-devel包：

yum install libatomic-devel

若yum源存在该包，安装后链接器会自动识别到对应的库文件。
