SuperLU link error with Armadillo

[padmasridharan]

I build superlu for windows as following some suggestions on commenting fortran compiler. Trying to use them in my application which uses armadillo as upper layer to call superlu gives me link error . I have linked superlu with armadillo and no issues there.
Any ideas or reasoning?

I don't understand your question. Do you mean that C code works with Armadillo, but Fortran code doesn't? Can you send the error message? Sherry

I have this issue when I compile it for armadillo. Do you know how to fix it?

It seems I have to compile it as run time library, but according to the information I obtained online, no one works. Btw, the version of SUPERLU for me is 5.2. Thank you!

Try recompile with another flag: -fPIC Sherry Li
