Eu tentei instalar a última versão do Clang e LLVM (3.9) ( http://releases.llvm.org/download.html#3.9.1 ) porque a versão do LLVM no Debian com o apt-get é o 3.5 ...
Mas como noob, eu não sei como, eu quebrei /usr/include:
#include <iostream>
int main()
{
std::cout << "Hello World!" << std::endl;
}
Eu tenho esse erro (versão do apt-get do clang, não o mais recente):
$ clang test.cpp
In file included from test.cpp:1:

wchar.h existe, mas está em uma subpasta de /usr/include:
$ find /usr/include -name 'wchar.h'
/usr/include/bsd/wchar.h
/usr/include/c++/4.9/tr1/wchar.h
/usr/include/x86_64-linux-gnu/bits/wchar.h
Como posso reinstalar e corrigir esses arquivos /usr/include?
