Question

我在ubuntu 18.4 LTS中使用gcc编译了BLAS和LAPACK库。 静态库与Armadillo标头一起正常工作，但是共享的lapack库却出现错误，其中包含28个未定义的blas函数引用，我认为它们是“ Extra Precise BLAS例程” ”。我不知道我是否在构建lapack共享库时出错了！犰狳的链接错误如下：

collect2：错误：ld返回1个退出状态

这是关于armadillo + Lapack（由netlib的LAPACK src构建的共享库。）的具体说明...我想知道这些BLAS例程的可能来源，而netlib的BLAS和LAPACK中没有这些例程！

XBLAS需要集成。详细信息可以在以下链接中找到。

Armadillo获取共享lapack库的未定义参考
