Hello
I'm trying to run a fortran code which use LAPACK subroutines. I
think I should use some points shown in the manual 5.5 Creating
shared objects but it is too technical for me :-(...
Be sure to look over section 6, esp. 6.17
The headers for DGEQRF, DLASR, DROT, DROTG are all in Blas.h or
Lapack.h (although you will see them in lower case).
XERBLA in libRBlas.so but is not in the R API, so if your code needs
to use it you'll have to add a header like the one in main.c or add
your own version.
Not in Fortran code, though: see below
I think Matthieu had not read quite a lot of the documentation: given
how carefully it was written, that was disrespectful (as was the lack
of a proper signature: see the posting guide: Charles aka Chuck has
been exemplary).
Sorry if this could be seen as disrespectful, I nevertheless don't think
that having difficulties to read a good but complex (and difficult for a
newbie) documentation is a sign of disrespect.
To put it simply: if you are ashamed of who you are, so are the most
prolific helpers here. Some people resent being milked for free
consultancy for commercial firms, and many of us will go many miles
out of our way for third-world NGOs/academia.
Oh, I forgot to write my name... I'm sorry, well even if you could see
it from my address I should have written. I understand your worry about
commercial firms, personnaly, I'm trying to contribute myself to R
through extensions of package tsDyn
http://code.google.com/p/tsdyn/wiki/ThresholdCointegration
I think you can probably do what you want with just
PKG_LIBS=${LAPACK_LIBS} $(BLAS_LIBS) ${FLIBS}
in Makevars
and
R CMD INSTALL <your-package>
with just the default settings.
This did the job (just had to copy/paste the xerbla in a proper .f file
in src)!
Thank you so much!
Agreed.
HTH,
Chuck
Could anyone help me for the procedure to do:
-which part of the manual is relevant for this type of question?
actually I'm speaking from writing R extensions, should I read R admin?
-point 1.2 says: /Recent versions of Autoconf in fact allow an
already set |FLIBS| to override the test for the FORTRAN linker
flags. Also, recent versions of R can detect external BLAS and
LAPACK libraries./
but nevertheless I have to include something more? or modify the
script?
-should I compile from SHLIB with other options or include it
directly into a package and cretae a makevars or PACKAGE_LIBS...?
I'm lost...
The subroutine I try to use is delcols.f
(http://www.maths.manchester.ac.uk/~clucas/updating/addcols.f) which
calls
* .. External Subroutines ..
EXTERNAL DGEQRF, DLASR, DROT, DROTG, XERBLA
Thank you very much!!
