[R] R 68.3 on OSF V4.0 problems

[Paul Szabo]

I am trying to install R-0.63.3 on a Digital Alpha running OSF V4.0D, and
having some difficulties. Can anyone help?

Also, I found some "oddities" in the installation process. I expect that
this message is read by the developers, maybe some of my suggestions can be
incorporated into future releases.

Please reply to me directly (as well as possibly also to this mailing list):
I am not a recipient of the list.


My problem is that floating-point operations seem weird. If I 'make' the
package as instructed, R quits (right after the welcome messages) with a
"floating exception"; if I change things so as not to use IEEE_754 (whatever
that means, and however 'configure' decided to use it), then the treatment
of 0/0 and the like (NaN, Inf) seems weird. Should not 'configure' pick the
correct options for my machine, and should not R recognize NaN and Inf?


The "oddities" of the build and installation process are:

Need cc (or ld?), not f77 for linking in src/main/Makefile (f77 has a nasty
habit of linking crt0.o or whatever).

Small bug in src/unix/Makefile causes needless re-makes.

Scripts COMPILE, INSTALL and SHLIB in src/scripts must use gmake, not the
DEC make (or I get the 'unknown option w' error).

The DEC shell /bin/sh has a weird (wrong?) treatment of "${@}", use ksh in
the main bin/R script.

For the installation, I like to keep things in the one directory, with
symlinks from /usr/local/bin and similar places. This allows easier
maintenance: I can build and install new versions as a non-root user. Root
does not need to run an "untrusted" makefile, but has only to create a few
symlinks. (I am root on my machines, but...)


Below is the shell script I used to build R so you can see exactly what I
done.


Thanks in advance for any help with my problem.
