I am sorry Peter, I am trying really hard to replicate this bug but I have
not been able to see the same result, no matter what I try.
I have download the latest tar ball and then I run:
$ ./configure --with-lapack="-llapack -lblas"
...
R is now configured for x86_64-unknown-linux-gnu
Source directory: .
Installation directory: /usr/local
C compiler: gcc -g -O2
C++ compiler: g++ -g -O2
Fortran compiler: gfortran -g -O2
Interfaces supported: X11
External libraries: readline
Additional capabilities: PNG, JPEG, iconv, MBCS, NLS
Options enabled: R profiling
Recommended packages: yes
$ make -j8
$ make check
It works.
OTOH I am not sure that configure is accepting my options. Looking into
config.log I don't see that value being used, and I noticed that the lapack
module it is still being built.
I read docs/manual/R-admin.html but without any difference. I have tried
different forms:
--with-lapack
--with-lapack="-llapack -lcblas"
--with-lapack="-llapack -lblas"
What am I missing?
