Question

我尝试在Vbu 7.4上安装YouCompleteMe，并在Ubuntu 15.10上添加了补丁1-712。

我已经通过hand编译了YouCompleteMe，因为我遇到了这样的错误：

/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC

如FAQ Section所述，添加-DPYTHON_LIBRARY=/usr/lib/libpython2.7.so即可解决问题。因此，请与此相提并论：

cmake -G "Unix Makefiles" -DPYTHON_LIBRARY=/usr/lib/libpython2.7.so . ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp

然后：

cmake --build . --target ycm_support_libs --config Release

我在编译这段时间时没有遇到任何错误，但是当我打开Vim I时，我看到了这一点：

   import ycm_client_support
                            ImportError: /home/austin/.vim/bundle/YouCompleteMe/third_party/ycmd/ycm_client_support.so: undefined symbol: PyUnicodeUCS2_AsWideChar

有谁知道如何解决这个问题？

这看起来像Python FAQ =＆gt;中描述的问题。 https://docs.python.org/2/faq/extending.html#when-importing-module-x-why-do-i-get-undefined-symbol-pyunicodeucs2

＆＃34;解决此问题的唯一方法是使用使用相同大小的Unicode字符构建的Python二进制文件编译的扩展模块。＆＃34;

您可以使用以下方法测试python的unicode字符大小：

import sys
if sys.maxunicode > 65535:
  print 'UCS4 build'
else:
  print 'UCS2 build'

安装YouCompleteMe后，Vim错误`未定义符号：PyUnicodeUCS2_AsWideChar`
