执行CMake构建ClickHouse时找不到LLVM LLD链接器的解决咨询

问题详情 #

构建ClickHouse时触发CMake错误，核心提示为：

CMake Error at cmake/tools.cmake:79 (message):
The only supported linker is LLVM's LLD, but we cannot find it.
Call Stack (most recent call first):
CMakeLists.txt:18 (include)

完整执行日志如下：

解决步骤 #

• 检查LLD是否存在：终端执行lld --version，若提示命令不存在，说明需要安装或指定路径。
• 若使用预编译LLVM包（如当前的clang 16.0.0），先确认LLD是否在clang安装目录下：
  查看/home/work/zjh/env/clang/16.0.0/clang+llvm-16.0.0/bin/目录，若存在lld或ld.lld，可在CMake命令中添加参数指定链接器：

  -DCMAKE_LINKER=/home/work/zjh/env/clang/16.0.0/clang+llvm-16.0.0/bin/lld
  

  或者将该目录加入系统PATH：

  export PATH=/home/work/zjh/env/clang/16.0.0/clang+llvm-16.0.0/bin:$PATH
  

• 若预编译包不含LLD，通过系统包管理器安装：
  • CentOS/RHEL：sudo yum install lld
  • Ubuntu/Debian：sudo apt install lld
• 处理日志中的libtinfo.so.5警告（可选但推荐）：
  CentOS/RHEL执行sudo yum install ncurses-compat-libs，Ubuntu/Debian执行sudo apt install libtinfo5，避免后续潜在问题。
