"R CMD check" accepts but "R CMD INSTALL" rejects a tar ball.

You may see warnings from the

This often indicates an invalid
archive: entry types ?"A-Z"? are
allowed as extensions, but other
types are reserved (this example
is from Mac OS 10.6.3). The
only thing you can do with such an
archive is to find a ?tar?
program that handles it, and look
carefully at the resulting files.
So the difference is whether you use external or internal
tar. 'g' is the global pax header extension so the format
you created is really pax and not tar (pax defines two new
types 'x' and 'g').

Okay, thanks. So I guess git-archive --format=tar uses GNU tar extensions (not too surprising). So this is documented... and a documented incompatibilities between different tar/tar extensions. But this behavior of R is a bit unexpected - When R CMD check (which involves installing to a temporary location then loads it and runs various things) works and R CMD INSTALL itself does not. OTOH, should this be reported to the GIT people?
I think you should re-read my e-mail more carefully -- those are not GNU extensions, those are headers used by pax, not tar. pax is a format inspired by tar and introduced in POSIX.1-2001, see http://en.wikipedia.org/wiki/Pax_(Unix) Cheers, Simon

I have somehow managed to made a source tar ball which
"R CMD check" accepts but "R CMD INSTALL" rejects with:
------------------ Warning in untar2(tarfile, files, list, exdir) : checksum error for entry 'pax_global_header' Error in untar2(tarfile, files, list, exdir) :
unsupported entry type ?g?
------------------ This happens with both R 2.12.2 (x86 linux) and R svn
(x86_64 linux). Since R CMD check does install as part of the check process, there is probably a bug somewhere. The tar ball is uploaded at:
http://htl10.users.sourceforge.net/tmp/Matrix_0.999375-48.tar.gz and tar -xzpvf works. It is possible to do R CMD
INSTALL from the untar'ed data, so I am a bit lost at where the problem is.
The tar ball was generated with git archive ... | gzip >
package.tar.gz
similar to the example at the bottom of git-archive. It is the result of git cherry-pick trunk at 2658 +
Matrix-for-R-2.13 at 2657 .
