如何显示详细的编译错误

[hqx871]

在column_predicate.h上加了个虚方法，编译失败，但是没有显示具体原因。请问如何显示具体是编译问题？

 virtual bool simplify(const BloomFilter* bf, ColumnPredicate* new_predicate) const {
        return false;
    }

./build.sh --be报错如下：
[ 61%] Linking CXX static library libOlap.a
[ 69%] Built target Olap
Makefile:148: recipe for target 'all' failed
make: *** [all] Error 2

这个是为了测试还是？如果是测试的话在最新的代码里这么试试康康报错栈？
