/usr/bin/ld: crtbegin.o：没有这个文件或目录

Question

我想安装llvm-clang，但在工作中没有root访问权限。我们的许多软件包已经过时，所以我正在本地在我的主目录下安装所有内容。

我已经安装了CMake和GCC，但现在在安装LLVM时遇到错误。

我的主目录结构如下：

~/gcc_build -> has the /bin directory which includes gcc, g++...etc (result of make install).

~/gcc-7.1.0 -> which has the main gcc build directory (where make was run)

~/llvm-4.0.0.src -> the main llvm directory 

~/llvm_make -> where I am trying to make llvm in (empty)

这是我的命令:

    [server-01:llvm_make]% ../cmake-3.8.2/bin/cmake ../llvm-4.0.0.src -DCMAKE_CXX_COMPILER=/home/sbay/gcc_build/bin/g++ -DCMAKE_C_COMPILER=/home/sbay/gcc_build/bin/gcc

但我遇到了这个错误：

[server-01:llvm_make]% ../cmake-3.8.2/bin/cmake ../llvm-4.0.0.src -DCMAKE_CXX_COMPILER=/home/sbay/gcc_build/bin/g++ -DCMAKE_C_COMPILER=/home/sbay/gcc_build/bin/gcc

您可以尝试添加--sysroot=选项，例如--sysroot=/home/lz/olimex/gcc-4.3.3/。

感谢您的评论，所以我添加了这个--sysroot=/home/sbay/gcc-7.1.0但是出现了这个错误：../cmake-3.8.2/bin/cmake ../llvm-4.0.0.src -DCMAKE_CXX_COMPILER=/home/sbay/gcc_build/bin/g++ -DCMAKE_C_COMPILER=/home/sbay/gcc_build/bin/gcc --sysroot=/home/sbay/gcc-7.1.0 CMake错误：源目录“/home/sbay/llvm_make/--sysroot=/home/sbay/gcc-7.1.0”不存在。 指定--help以获取用法信息，或按下CMake GUI上的帮助按钮。 - SFbay007

我的错，我添加了-DCMAKE_SYSROOT=/home/sbay/gcc-7.1.0，现在出现的错误是：/usr/bin/ld：该链接器未配置为使用sysroots。 - SFbay007

我猜你得找到其他的gcc版本或者启用sysroot来构建。 - LZ041

我现在已经下载了binutils并正在构建它。你认为我使用本地版本的ld会起作用吗？如何启用sysroot进行构建？我已经执行了./configure;make。这是错误的方法吗？ - SFbay007

你认为我使用本地版本的ld会行吗？如果你的本地版本比较旧，很可能不起作用。你需要像--with-sysroot这样在./configure中添加一些内容（检查它有哪些选项）。 - LZ041
