error when install spconv1.2.1：error: cannot call member function ‘void std::basic_string＜_CharT, _Traits, _Alloc＞::

problem track¶

When running the cylinder3D package, I need to install spconv1.2.1, and the error is reported as follows:

/usr/include/c++/7/bits/basic_string.tcc:1067:16: error: cannot call member function 'void std::basic_string<_CharT, _Traits, _Alloc>::_Rep::_M_set_sharable() [with _CharT = char16_t; _Traits = std::char_traits<char16_t>; _Alloc = std::allocator<char16_t>]' without object
        __p->_M_set_sharable();

solution¶

In /usr/include/c++/7/bits/basic_string.tcc:1067:16:

sudo gedit /usr/include/c++/7/bits/basic_string.tcc

change:

__p->_M_set_sharable()

to:

(*__p)._M_set_sharable()

problem solved! ! !
