Version: 2.11.0-1
Severity: normal
Hello,
I stumbled upon this issue while analizing kdeedu FTBFS [1] on armel. It is
caused by likely buggy kdeedu buildsystem settings when
/usr/lib/R/lib/libRlapack.so is present. So it is not the fault of the
r-base-core package directly.
But this issue left me wondering why armel is the *only* architecture which
still builds /usr/lib/R/lib/lib{Rblas,Rlapack}.so:
$ wget -O amd64_filelist
http://packages.debian.org/sid/amd64/r-base-core/filelist
$ wget -O armel_filelist

Then I saw this old code in debian/rules:
# edd 14 Nov 2003 turn blas off on arm
ifeq ($(arch),arm)
atlas = --without-blas
endif
As far as I can tell, --without-blas disables detection of system blas at
configure stage. But libblas-dev build dependency is NOT arch specific (or it
should be [!armel]). What is more, there is also the following at m4/R.m4:2894
# We cannot use LAPACK if BLAS is not found
if test "x${acx_blas_ok}" != xyes; then
acx_lapack_ok=noblas
fi
So system lapack cannot be used if system blas is not used yet --with-lapack is
passed to configure on armel by debian/rules. And again, liblapack-dev build
dependency is NOT architecture specific.
So my question is if that --without-blas is still intentional nowadays. I would
appretiate quick answer or upload because kdeedu is part of ongoing KDE SC
4.4.3 transition. Initial 10 days is about to expire for majority of other KDE
SC packages.
If /usr/lib/R/lib/libRlapack.so is intentional on armel, I will have to fix
kdeedu build system and if it is not, I could wait a bit until fixed r-base is
uploaded to sid and request a give back.
