R help - May 2000 - problem with ts package

I just encountered a problem with the ts package:
> library(ts)
Error in dyn.load(x, as.logical(local), as.logical(now)) :
        unable to load shared library
"/usr/local/lib/R/library/ts/libs/ts.so":
  /usr/local/lib/R/library/ts/libs/ts.so: undefined symbol: ma

My environment is

R 1.0.1
RedHat  6.2  for intel.
> R.Version()$system
[1] "i686, linux"


I just updated RedHat from 6.1. Under 6.1, that version of R
worked fine.

Thanks for any help on this.

Cheers,
Christian

Simple Qs:

1) did you build R yourself or are you using an RPM?
2) If you did build it, have you tried re-building it under 6.2?

BTW: I think your subject line is misleading: the problem is with the
system upgrade, not the ts package. (And the package maintainer does care
about the distinction.)

I have no idea what is going on: ma is not a symbol in the ts package,
so the problem is definitely elsewhere. We do know that this works
correctly when compiled and run on an RH6.2 system.

Yup, on mine for instance. However, I think I upgraded to 6.2 before
1.0.1 came out.

For some odd reason I still have a 0.65.0 sitting here and that one
still loads the (then preliminary) ts quite OK.

Our R 1.0.1 was compiled *before* the upgrade (from 6.1) to 6.2
and library(ts) still works.

[BTW, nice to hear from you, Christian!]

I''m afraid dlerror() can return garbage on RH6.2 so the
"undefined symbol: ma" message is probably not helpful.

The latest R RPM for Red Hat Linux is compiled on RH6.2 and works fine.
I suggest you try that.
