Error when running: "libclang.so: cannot open shared object file: No such file or directory"

[stepthom]

First, I ran sudo apt-get install python-yaml and sudo pip install clang. Success.

Then I tried:

[dev@ubuntu:~/cncc (master)] $ ls
cncc  examples  LICENSE  MyClass.cpp  MyClass.h  README.md  util
[dev@ubuntu:~/cncc (master)] $ git log -1

    Respect global style file, closes #5

    Local style files do not seem to make a lot sense. What we could do is
    walk all parent directories like `clang-format` does, though.
[dev@ubuntu:~/cncc (master)] $ cat MyClass.h 
class MyClass{
public:
    void init(int a, int b);
    int loopAlot();
private:
    int var1, var2;
};

[dev@ubuntu:~/cncc (master)] $ cat MyClass.cpp 
#include "MyClass.h"

void MyClass::init(int a, int b){
    var1 = a;
    var2 = b;
}

int MyClass::loopAlot(){
    int res = this->var1 + var2;
    for(int i=0; i<this->var1; ++i){
        res = res + this->var2;
    }
    return res;
}
[dev@ubuntu:~/cncc (master)] $ ./cncc --style=examples/basic.style MyClass.cpp

    raise LibclangError(msg)
clang.cindex.LibclangError: libclang.so: cannot open shared object file: No such file or directory. To provide a path to libclang use Config.set_library_path() or Config.set_library_file().

Any idea what I'm doing wrong?

Sorry for not responding earlier, seems like I overlooked the notification.

You do not have a matching libclang native shared library for the Python wrapper that python-clang is supposed to wrap. I found PyPI to not provide wrappers compatible with every clang version. That is, check your clang --version, and then see if PyPI has a matching wrapper for this (I think the one for 3.6 was missing, and e.g. Ubuntu 15.04 comes with Clang 3.6).

That's the main reason this issue was never resolved.

The easiest way to install python-clang is by means of your package manager, e.g. aptitude on Debian-based systems.

Hi, for who have problem with python-clang, make a simbolic link for the same version of native clang and the python-bind:
cd /usr/lib/x86_64-linux-gnu/
sudo ln -s libclang-3.8.so.1 libclang.so
