So, tried again from scratch. Again, CentOS 5.3, which is essentially
RHEL 5.3.
./configure --with-blas="-L/opt/acml4.3.0/gfortran64/lib -lacml"
In config.log, get things like
configure:37199: checking for dgemm_ in -L/opt/acml4.3.0/gfortran64/lib
-lacml
configure:37230: gcc -std=gnu99 -o conftest -g -O2
-I/usr/local/include -L/usr/local/lib64 conftest.c
-L/opt/acml4.3.0/gfortran64/lib -lacml -$
conftest.c: In function 'main':
conftest.c:189: warning: implicit declaration of function 'dgemm_'
/usr/bin/ld: warning: libgfortran.so.3, needed by
/opt/acml4.3.0/gfortran64/lib/libacml.so, not found (try using -rpath or
-rpath-link)
Try
./configure --with-blas="-L/usr/lib64/atlas -lf77blas -latlas"
I get the following
configure:37199: checking for dgemm_ in -L/usr/lib64/atlas -lf77blas -latlas
configure:37230: gcc -std=gnu99 -o conftest -g -O2
-I/usr/local/include -L/usr/local/lib64 conftest.c -L/usr/lib64/atlas
-lf77blas -latlas -lg$
conftest.c: In function 'main':
conftest.c:189: warning: implicit declaration of function 'dgemm_'
/usr/bin/ld: cannot find -lf77blas
collect2: ld returned 1 exit status
configure:37236: $? = 1
configure: failed program was:
What puzzles me is that lf77blas is definitely in /usr/lib64/atlas -
but configure couldn't find it (?). Perhaps its because 100% of the libs
in the atlast subdir are xxx.so.3 (perhaps R config is looking for so.1
libs?).
I suspect that many/most of the problems I'm having with getting R to
compile (with BLAS and LAPACK) are related to these basic issues - if I
can't do even a simple compile with blas, then whats left?
