==> Pouring binutils--2.36.1.big_sur.bottle.tar.gz
==> Caveats
binutils is keg-only, which means it was not symlinked into /usr/local,
because Apple's CLT provides the same tools.

If you need to have binutils first in your PATH, run:
  echo 'export PATH="/usr/local/opt/binutils/bin:$PATH"' >> ~/.zshrc

For compilers to find binutils you may need to set:
  export LDFLAGS="-L/usr/local/opt/binutils/lib"
  export CPPFLAGS="-I/usr/local/opt/binutils/include"

==> Summary
🍺  /usr/local/Cellar/binutils/2.36.1: 83 files, 159.4MB

$ mdfind -name objcopy

$mdfind -name objcopy
/usr/local/Cellar/binutils/2.36.1/share/man/man1/objcopy.1
/usr/local/Cellar/binutils/2.36.1/x86_64-apple-darwin20.2.0/bin/objcopy
/usr/local/Cellar/binutils/2.36.1/bin/objcopy
/Users/bytedance/soft/ClickHouse/contrib/llvm/llvm/utils/gn/secondary/llvm/tools/llvm-objcopy

then find the file ~/ClickHouse/CMakeLists.txt

origin: find_program (OBJCOPY_PATH NAMES "llvm-objcopy" "llvm-objcopy-10" "llvm-objcopy-9" "llvm-objcopy-8" "objcopy"

# Make sure the final executable has symbols exported
set (CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -rdynamic")

find_program (OBJCOPY_PATH NAMES "llvm-objcopy" "llvm-objcopy-12" "llvm-objcopy-11" "llvm-objcopy-10" "llvm-objcopy-9" "llvm-objcopy-8" "objcopy")

changed:

# Make sure the final executable has symbols exported
set (CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -rdynamic")

find_program (OBJCOPY_PATH NAMES "llvm-objcopy" "llvm-objcopy-10" "llvm-objcopy-9" "llvm-objcopy-8" "objcopy" PATHS "/usr/local/Cellar/binutils/2.36.1/bin/")

e.g:

# Make sure the final executable has symbols exported
set (CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -rdynamic")

# find_program (OBJCOPY_PATH NAMES "llvm-objcopy" "llvm-objcopy-12" "llvm-objcopy-11" "llvm-objcopy-10" "llvm-objcopy-9" "llvm-objcopy-8" "objcopy")

find_program (OBJCOPY_PATH NAMES "llvm-objcopy" "llvm-objcopy-10" "llvm-objcopy-9" "llvm-objcopy-8" "objcopy" PATHS "/usr/local/Cellar/binutils/2.36.1/bin/")

then you can follow the command, and you can build successfully.

CMake Warning (dev):
  Policy CMP0068 is not set: RPATH settings on macOS do not affect
  install_name.  Run "cmake --help-policy CMP0068" for policy details.  Use
  the cmake_policy command to set the policy and suppress this warning.

  For compatibility with older versions of CMake, the install_name fields for
  the following targets are still affected by RPATH settings:

   cassandra
   uv

This warning is for project developers.  Use -Wno-dev to suppress it.

注意事项

若你想运行 clickhouse-server，请先确保增加系统的最大文件数配置。

注意

可能需要用 sudo

为此，请创建以下文件：

/资源库/LaunchDaemons/limit.maxfiles.plist:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"

 "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

 <dict>

 <key>Label</key>

 <string>limit.maxfiles</string>

 <key>ProgramArguments</key>

 <array>

 <string>launchctl</string>

 <string>limit</string>

 <string>maxfiles</string>

 <string>524288</string>

 <string>524288</string>

 </array>

 <key>RunAtLoad</key>

 <true/>

 <key>ServiceIPC</key>

 <false/>

 </dict>

</plist>

执行以下命令：

$ sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist

然后重启。

可以通过

ulimit -n

命令来检查是否生效。
