This is odd since the LAPACK subroutine dgemv takes only 11 parameters.
However, in include/R_ext/BLAS.h we have
F77_NAME(dgemv)(const char *trans, const int *m, const int *n,
const double *alpha, const double *a, const int *lda,
const double *x, const int *incx, const double *beta,
double *y, const int *incy FCLEN);
with a 12th parameter FCLEN?? How am I supposed to fix this, and what
the ... is FCLEN? googling leads to nothing useful (for me). It seems as
if R is redefining some standard LAPACK routines.
Also a note I do not understand (in this context):
note: type ‘void’ should match type ‘long int’
Any help is much appreciated.
Sounds likely to be related to this item from R-devel NEWS:
http://developer.r-project.org/blosxom.cgi/R-devel/2019/08/29#n2019-08-29
" Header ‘Rconfig.h’ contains the value of ‘FC_LEN_T’ deduced at
installation which is used by the prototypes in headers ‘R_ext/BLAS.h’
and ‘R_ext/Lapack.h’ but to avoid extensive breakage this is only
exposed when ‘USE_FC_LEN_T’ is defined.
If a package's C/C++ calls to BLAS/LAPACK allow for the ‘hidden’
arguments used by most Fortran compilers to pass the lengths of Fortran
character arguments, define ‘USE_FC_LEN_T’ and include ‘Rconfig.h’
(possibly _via_ ‘R.h’) before including ‘R_ext/BLAS.h’ or
‘R_ext/Lapack.h’."
Thanks Duncan,
but my call to dgemv is from a FORTRAN subroutine, no C is involved. It
is called by .Fortran in R code. I am confused (not for the first time).
