I would like to report a minor problem compiling sage
-----------
* my environment:
laptop running Fedora 2.6.23.15-137.fc8
with the intle mkl libraries (blas, lapack) installed
environmental variables CPPFLAGS and LDFLAGS
are set to point to the intel include and lib directories respectively.
---------------------------
problems building sage 2.10.1
* two packages configured themselves to use intel's libraries,
but tried to link (both!) -lmkl_lapack64 and -lmkl_lapack32
(I lost the log, but I believe they were numpy and scipy)
work-around: I created links in /usr/local/lib to point libmkl_lapack32.so
and libmkl_lapack64.so to $INTEL_MKL/lib/32/libmkl_lapack.so
* a question about the R package:
I would prefer to have R installed only once, but I require some config
switches.
My current method is to
1) use "sage -sh" to set the environmental variables,
2) untar the R package,
3) modify the configure line to read
./configure --prefix="$SAGE_LOCAL" \
--with-recommended-packages=yes \
--enable-R-shlib \
--with-x=$XSUPPORT \
--with-readline="$SAGE_LOCAL" \
--with-blas="-lmkl -lguide -lpthread" \
--with-lapack="-lmkl_lapack"
4) make and install R
5)
restore a saved version of the R library directory
(where R installs optional packages)
Questions:
- is there a way to streamline this? (I could always
write a shell script...)
Having the script not erase the R/library subdirectory
in the first place would be a big plus
- since sage developers readily modify packages,
is there an easy way to find out whether R might
have been
customized
(possibly requiring reinstallation
of all my additional R packages?)
----------------------------------
PS: thank you all for all the work you are doing, sage is proving
very useful indeed!
