Summary: build error on 0.3.6 cannot find -lRlapack

Initial Comment:
I've successfu0lly built and used rkward-0.3.5.  I was
trying to create a Gentoo ebuild package file for
rkward 0.3.6 so that upgrades would be easier, and
distribution of rkward would be greater.  From both the
ebuild and from trying to build from a shell, the build
fails with the following:

I think that lib Rlapack is missing.  I'm wondering if
this is something configured wrong in the build
configuration. 

I'm using R-2.2.1 with blas and lapack support compiled in.

I'm using lapack-3.0, and blas-19980702-r2.

When I look for lapack libraries that could be linked
with rkward, I see:

/usr/lib/R/modules/lapack.so
/usr/lib/liblapack.a
/usr/lib/lapack
/usr/lib/lapack/atlas
/usr/lib/lapack/atlas/liblapack.so.0
/usr/lib/lapack/atlas/liblapack.so.0.0.0
/usr/lib/lapack/atlas/liblapack.so
/usr/lib/lapack/atlas/liblapack.la
/usr/lib/lapack/atlas/liblapack.a
/usr/lib/lapack/current
/usr/lib/lapack/f77-ATLAS
/usr/lib/liblapack.so
/usr/lib/liblapack.so.0

So, I suspect that rkward probably needs 
/usr/lib/R/modules/lapack.so (what else could Rlapack
be?).  I tried a symbolic link from 
sudo ln -s /usr/lib/R/modules/lapack.so
/usr/lib/Rlapack.so 
but that didn't do it.

I'll try to look deeper into the code at issue, but any
assistance would be appreciated.

Regards,

Thanks for your bug-report, and of course thanks for your
packaging efforts!

In RKWard 0.3.6 I added the -lRlapack switch, as otherwise,
with R 2.3.0, sometimes some base packages could not be
loaded due to unresolved symbols. RKWard itself does not use
the library, but this way it loads it for R packages to use.
I have not fully investigated, why exactly this happens.
In fact, ATM, I do not seem to be able to reproduce this.
Maybe it was a temporary bug in one of the pre-release
versions of R 2.3.0 I tested, and has since been fixed. I do
not know, and would appreciate any insight.

Ok, how to work around this? Probably the most
straightforward way would be to edit rkward/Makefile.am and
remove the -lRlapack switch there (I do not know, whether
this is possible in gentoo packaging, but I hope so). If
everything works fine, then (remember to test with R 2.3.0,
too), that should be the best way, and I'll probably remove
the switch in the next release of RKWard (after some more
testing).

You might also try some other things first:
1) ln -s /usr/lib/R/modules/lapack.so
/usr/lib/R/lib/libRlapack.so (that is the location ldd will
be searching for -lRlapack)
2) Upgrade to R 2.3.0. Maybe some configuration options
changed there.

Please keep me up-to-date on whether or not this works.

Regards
Thomas

P.S.: Please don't set the "Assigned to" field, when
submitting bug reports. We don't really use this field ATM,
but it's rather intended to be an internal way of signalling
"I'm taking care of this" among the developers, not a
setting intended to be made by the submitter.
