END PROGRAM solver_f90_test请教各位大佬，附件dss_sym_f90.f90为mkl的一个例子。想通过gfortan调用MKL编译这个例子，但一直报错。gfortran的编译选项如下所示（根据intel ineAPI Math Kernel Library Link Line Advisor得到的），但是链接报错，不知道怎么回事？

我上次遇到过类似许多未定义的错误(undefined reference) ，最后发现是路径错误。你的这个dss_sym_f90.f90.o很奇怪，如果是dss_sym_f90.f90编译后的object文件，后缀是dss_sym_f90.o。我感觉是你make的时候文件名弄错了。 zjk0112 发表于 2022-7-12 16:03

我也是路径不对:-L Neo123 发表于 2022-7-13 18:19
我也是路径不对
问题解决了就好
