Hello All,
I have been trying to figure out on linking R with an external
lapack. Even though the R-admin recommends against doing so, our
requirements force us to link it to an external lapack. I am running
configure with the following parameter.
*./configure --with-lapack="-L/usr/lib -llapack -lcblas" *
The above seems to be having NO effect. However, later I tried replacing
libRlapack, libblas and lapack.so from $(R_HOME)/lib and $(R_HOME)/modules/
with external lapack. Firstly, is this good?
No, and the cause of your failure below.
Why do you think '-lcblas' is correct? Please do follow the manual -- if
you still have trouble when you do it is reasonable to ask for help, but
not otherwise.
Secondly, after doing the above. When I do.
When I do
example(svd)
The following is the error that I am getting:
*Error: segfault from C stack overflow*
On debugging the error was in La_Init() at Line 61
*if(!ptr->svd)*
I am getting a SIGSEGV over here.
Could anybody provide an pointers or and tips on how to link R with an
external lapack? And also possibly the cause of the above issues?
Follow the manual -- its instructions do work (they are used on Mac OS X,
and will also work on Linux and Solaris).
TIA.
Regards,
