[R-pkg-devel] Package or namespace load failed: undefined symbol

[Sameh M. Abdulah]

Dear   Ralf

My package depends on another C-based software that needs LAPACKE to compile. I do not know a lot about it. I think adding LAPACKE to my package will be a good solution.
Could you please give me more information of how to do this?

    I seem to be missing some context here. I might be able to help you if
    provide a higher level description of what you are trying to achieve.
    For example, why do you need LAPACKE instead of the C interface to
    LAPACK provided by R_ext/Lapack.h? And if you really need LAPACKE, why
    not include only that in your package and link with the BLAS/LAPACK
    used by R?
