[Rcpp-devel] continuing attempts with throw/catch problem

[Ben Bolker]

  [previously sent to Dirk but here in case anyone else is interested,
and for archival purposes]

  Things are feeling alarmingly non-deterministic, but that may be
because I've been sloppy.  I've been working mostly with a stock R
2.12.1 install (Ubuntu 10.10), but have also tried R-devel and a
custom-compiled R 2.12.1 (at various times configured --with-blas,
--with-lapack OR --without-blas, --without-lapack: as I understand it I
should stick with the --with variant and use Dirk's tools to manipulate
which libraries are actually used?)

  This script ought to work anywhere, as long as lme4a is installed (I'm
using ...-60, which is a fresh install from r-forge), gcbd is installed
(CRAN), and you have network access ...

  Note that lme4a does **not** seem to work with Rcpp 0.9.0.2 (fresh
R-forge install), but does (except for this particular problem) with
Rcpp 0.9.0 (fresh CRAN install).

library(gcbd)  ## utilities for messing with BLAS/ATLAS etc.
tryscript <- function() {
source(url("http://www.math.mcmaster.ca/bolker/R/misc/throw.R")) }
## make sure no accelerated packages are present
purgeAtlas()
purgeAtlas39()
purgeGoto()
purgeMKL()
tryscript()
installAtlas() ## restore Atlas ...

  Is there anyone out there *besides me* for whom this crashes at
tryscript()?  It seems to happen whether I purgeAtlas() or not.  Is it
necessary

  When I try this in R-devel after purging Atlas I get:

Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared object
'/mnt/hgfs/bolker/Documents/R/r-devel/R/library/lme4a/libs/lme4a.so':
  libf77blas.so.3gf: cannot open shared object file: No such file or
directory
Error: package/namespace load failed for 'lme4a'

  when I try again I get:

> installAtlas()
> tryscript()

Attaching package: 'lme4a'

The following object(s) are masked from 'package:stats':

    AIC

npt = 3 , n =  1
rhobeg =  0.2 , rhoend =  2e-07
terminate called after throwing an instance of 'Rcpp::eval_error'
  what():  Lapack routine dpotrf returned error code

  Any more clues?
