错误：无法将'boost :: shared_ptr <permlib :: Permutation>'转换为'bool'以返回return repr;

我是linux的新手，并尝试在Linux中安装SymBol。 SymBol要求

Boost in version 1.34.1 or higher
GMP with both C and C++ bindings
CMake in version 2.6 or higher

我成功安装了这3个但是当我想安装SymPol时出现这个错误：

cannot convert ‘boost::shared_ptr<permlib::Permutation>’ to ‘bool’ in return
return repr;
