Armadillo正在为共享的lapack库获取未定义的参考

Question

我已经在ubuntu 18.4 LTS中使用gcc编译了BLAS和LAPACK库。静态库在Armadillo头文件中运行良好，但共享的lapack库出现错误有28个未定义的blas函数引用，我认为这些函数是">超精确blas例程"。我不知道我是否在构建lapack共享库时出错了？！armadillo的链接错误如下：

它非常具体地关于armadillo+Lapack(从netlib的Lapack src.构建的共享库(……我想知道这些在netlib的BLAS和Lapack中不可用的BLAS例程的可能来源！

XBLAS需要集成。。详细信息可在以下链接中找到。
