Hi!
Please add b-d for gfortran-4.1 (Fixes FTBFS).
That FTBFS is on ubuntu, am I right? I think it needs fixing, there,
and
adding gfortran-4.1 as bd will not help. The situation is as follows:
- In debian, starting with 2.5.1-1, R is forced to build with GCC
4.2. I don't
know the exact reasons, but according to the changelog, there were
some
problems with mis-compilation of fortran code with gfortran 4.1.
- For rkward we needed to follow suit in order to get correct
linking. Since
we try to support a large range of different installations with a
single .deb, we only force GCC 4.2 when the installed version of R
is 2.5.1
or greater.
- The relevant build-depends are fetched via r-base-dev, which, in
debian,
depends on gcc/g++/gfortran 4.2.
- Now in ubuntu apparently the forcing of GCC 4.2 was reverted.
Here's the
changelog message for 2.6.0-3gutsy0:
r-base (2.6.0-3gutsy0) gutsy; urgency=low
.
* Compilation for Ubuntu 7.10
* build-depends on poppler-utils instead of xpdf-reader
* reverted build-depends to gcc, g++ and gfortran instead of
gcc-4.2,
g++-4.2 and gfortran-4.2
(@Vincent: That's why I put you in the CC)
Yes, this is needed since no Ubuntu to date has gcc 4.2 (the version
on Gutsy is 4.1.3). Now, as to why the change was needed on Debian in
the first place, Dirk (in CC) is better able to answer than I am.
(Honestly, I never really understood why Ubuntu can do without the
Debian gcc >= 4.2 requirement.)

I can see no good way of coping with this from the rkward debian
package.
Rather, I think you will need to prepare a ubuntu-specific package
of rkward,
just as you did for r-base. To do so, simply remove the logic in
lines 30 to
39 of debian/rules (leave only the portion inside the else...fi). No
other
changes should be needed. But again, I can see no good way of
adjusting the
debian package, and will close this report unless you manage to
convince me
otherwise.
