When I make with Python 3.7, it produces error messages:
./io/FetchPythonData.cpp: In function 'void FetchData(char**, PyObject*)':
./io/FetchPythonData.cpp:1302:25: error: invalid conversion from 'const char*' to 'char*' [-fpermissive]
1302 | string=PyUnicode_AsUTF8(py_string);
| ~~~~~~~~~~~~~~~~^~~~~~~~~~~
| |
| const char*
It is due to the change of PyUnicode_AsUTF8() return type whose reference is here. So I think it should be modified to be compatible to Python 3.7.
We can fix it in ${ISSM_DIR}/src/wrappers/python/io/FetchPythonData.cpp. In void FetchData(char**, PyObject*) function, add const qualifier to the declaration of string.
As a result,
void FetchData(char** pstring,PyObject* py_string){
const char* string=NULL;
/*extract internal string: */
#if _PYTHON_MAJOR_ == 3
string=PyUnicode_AsUTF8(py_string);
#else
string=PyString_AsString(py_string);
#endif
/*copy string (note strlen does not include trailing NULL): */
*pstring=xNew<char>(strlen(string)+1);
memcpy(*pstring,string,(strlen(string)+1)*sizeof(char));
}
