Question

我想通过使用库编译一个简单的程序来测试我的MKL安装：

#include <iostream>
#include <mkl.h>

int main(void)
{
        std::cout << "Hello World\n";
        return 0;
}

现在通过使用MKL Link Line Advisor，我得到以下编译行：

g++ -DMKL_ILP64 -m64 -I${MKLROOT}/include test.cpp -L${MKLROOT}/lib/intel64 -Wl,--no-as-needed -lmkl_intel_ilp64 -lmkl_gnu_thread -lmkl_core -lgomp -lpthread -lm -ldl -o test

使用GCC-6.3.0并将MKLROOT设置为正确的路径。但是在编译时，我得到了

我的MKL装置坏了吗？或者我忘记了别的什么？

Answer 1

你能试试吗？ -L $ {MKLROOT} / lib / intel64 Wl， - no-as-needed -lmkl_rt -lpthread -lm -ldl

Answer 2

删除选项-ldl时，它有效，但我没有解释，为什么。

对MKL库的简单链接测试失败
