registering Fortran routines in R packages
Thanks for your email.
I try to change the name in lowercase but it conflicts with a C implementation also named halton. So I rename the C function halton2() and sobol2() while the Fortran function are HALTON() and SOBOL() (I also try lower case in the Fortran code). Unfortunately, it does not help since I get
init.c:97:25: error: use of undeclared identifier 'halton_'; did you mean

I did come across geigen while rooting around in the CCA code but its not formally documented (it just says "for internal use" or something along those lines) and as you found out above, it does not produce the same solution as the dggev. It would be nice to have a more complete set of formal packages for doing...

Have a look at my package geigen and its init.c.
Could it be that you are missing extern declarations for the Fortran routines?
