YouCompleteMe 安装问题

Question

我正在尝试在运行 Debian Linux 的大学服务器上安装 YouCompleteMe（在我的用户家中）。 当我跑步时：

./install.sh

在“构建 CXX 对象”阶段后出现以下错误。

错误消息显示“使用 -fPIC 重新编译”我必须重新编译什么？谢谢。

Answer 1

我刚刚解决了这个问题；和你一样：我安装了自己的 Python。我引用了this solution，但我的做法有点不同。

1. 首先检查您自己的 lib 目录中是否有 libpython2.7.so（在您的情况下是 ~/lib/）。如果只有libpython2.7.a，则可能需要为共享库重新编译python。查看this 以供参考。总之你应该去你的python源代码，并且：

   ./configure --enable-shared \
               --prefix=$HOME \
               LDFLAGS="-Wl,--rpath=$HOME/lib
   make
   make install
   

2. 如果您的系统本身有 Python，您可能会遇到麻烦。问题如下：

/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32 against `.rodata.str1.8' 不能在制作共享对象时使用；使用 -fPIC /usr/local/lib/libpython2.7.a 重新编译：无法读取符号：错误值

在这种情况下，请参考this solution并返回步骤1。

否则，请继续。

1. 现在我假设你的 lib 目录中有 libpython2.7.so。稍微改一下~/.vim/bundle/YouCompleteMe/third_party/ycmd/build.py：

   • 修改函数CustomPythonCmakeArgs()，替换

     python_library = '{0}.a'.format( lib_python )
     

     与

     python_library = '{0}.so'.format( lib_python )
     

   • 在附近添加一条线

     python_executable = '{0}/bin/python'.format( python_prefix )
     

   您的 python 解释器可能位于其他位置，请相应地进行更改。

   • 从

     改变返回值

     return [
         '-DPYTHON_LIBRARY={0}'.format( python_library ),
         '-DPYTHON_INCLUDE_DIR={0}'.format( python_include ),
     ]
     

     到

     return [
         '-DPYTHON_LIBRARY={0}'.format( python_library ),
         '-DPYTHON_INCLUDE_DIR={0}'.format( python_include ),
         '-DPYTHON_EXECUTABLE={0}'.format( python_executable ), 
     ]
     

   • 还记得注释掉

     if OnMac():
         full_cmake_args.extend( CustomPythonCmakeArgs() )
     

     喜欢这个

     # if OnMac():
     full_cmake_args.extend( CustomPythonCmakeArgs() )
     

做完这些你应该就好了。回到~/.vim/bundle/YouCompleteMe重新安装

./install.py --clang-completer
