Encountered error in connecting the C++ and pypy with cppyy

Question

I wrote a class header file like this, all steps follows this page cppyy

class MyClass {
public:
    MyClass(int i = -99) : m_myint(i) {}

    int GetMyInt() { return m_myint; }
    void SetMyInt(int i) { m_myint = i; }

public:
    int m_myint;
};

And then compile it

$ genreflex MyClass.h
$ g++ -fPIC -rdynamic -O2 -shared -I$REFLEXHOME/include MyClass_rflx.cpp -o libMyClassDict.so -L$REFLEXHOME/lib -lReflex

Load to pypy-c

$ pypy-c
>>>> import cppyy
>>>> cppyy.load_reflection_info("libMyClassDict.so")

Then I got this error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
RuntimeError: libMyClassDict.so: cannot open shared object file: No such file or directory

Anyone has encountered this problem, help me please!

Answer 1

(solved after discussion in the pypy mailing list)

The issue was that "libMyClassDict.so" is looked up in the system's standard paths (not including "."). You need to say "./libMyClassDict.so".
