Dear all,
R on Macports relies on GCC 4.3 to build packages. I find that
packages with shared objects that use C++ streams crash R if
they're compiled using Macports' gcc43, but work fine if compiled
in exactly the same way using Apple-supplied GCC 4.2. Has anyone
here had the same issue/know what is causing this problem?
Using compilers from MacPorts and similar suites (Darwin ports,
Fink etc.) is strongly discouraged (and outright not supported by
the CRAN binary) since they have been known to be badly broken in
the past and when whenever tested so far they were incomplete and
incompatible. You have to re-compile R yourself with those tools
(and you're entirely on your own) if you really want to use them.
CRAN binaries work only with Apple's gcc branches, if you want to
use anything else, you have to follow the unix R instructions and
compile everything from sources.
Dear Kjell,
As you can see above, your R port on Macports appears to be broken
and has a reputation of having been broken for a while. I for one
have experienced odd problems as described above. To avoid further
issues with unsuspecting Macports users, perhaps it would be good to
pull the port from the repository until a decent level of
reliability can be provided ?
Although I do agree on your last point, I just want to clarify that I
was talking about supported R for Mac setup (as provided in binary
form on CRAN). Although it should be possible to build R with non-
Apple gcc, but it must be done very carefully, because there are many
dangers lurking in the interaction of system libraries with those from
non-Apple tools. This has nothing to do with R, it's about knowledge
how things work in OS X and it is very important when compilers are
involved [unfortunately there are many binaries around from people
that don't understand the intricacies of OS X well enough and think
it's almost like a Linux box - I'm not talking about MacPorts in
particular, it's just a general observation].
Cheers,
Simon
