Advice on linking D programs to fortran77 blas/lapack

[Michael Gratton]

Hello,

I'm trying to link a D program to the BLAS and LAPACK libraries (numerical linear algebra packages usually written in FORTRAN77).

I've written an extern (C) {} block much like I would in C/C++ to provide "headers" for the functions I want to call, and then tried to build the program by

dmd test.d /usr/lib/libblas.a /usr/lib/liblapack.a

This nearly works, but LAPACK complains that several _gfortran symbols are undefined, such as:

(.text+0x83): undefined reference to `_gfortran_compare_string'
(.text+0x341): undefined reference to `_gfortran_copy_string'
(.text+0x69): undefined reference to `_gfortran_st_write'

...and so on.  Has anyone else had luck with this kind of linking?  Am I missing a library that gcc magically includes when linking C and F77?  Am I just flat trying to link wrong with the dmd command?

Thanks!
