Question

我正在尝试编译一个使用Lapack函数的代码。我按照（http://www.netlib.org/lapack/lawnspdf/lawn81.pdf）的主要说明安装了Lapack和BLAS，我运行了测试，听起来不错。

然而，当我跑步时：

gfortran -L/home/user/Desktop/LAPACK -I/home/user/Desktop/LAPACK/include -llapack -llapacke -lrefblas -O3 lorenz96v4.f90 -o l96_2.x -ffree-line-length-200

我获得了一堆错误（见下文）。库liblapak.a和librefblas.a包含在/ home / user / Desktop / LAPACK中，所有头文件都在其中的include文件夹中。

以下是错误消息：

看起来编译器无法识别或找到标题......任何人都可以帮助我吗？

Answer 1

试试这个：

ln -s /home/user/Desktop/LAPACK/librefblas.a /home/user/Desktop/LAPACK/libblas.a

还使用-lblas并更改链接顺序：

-llapacke -llapack -lblas

即使在包含-lreflblas之后，未定义的BLAS也会起作用
