Simon,
thanks for the suggestion. I downloaded gmp-4.3.1-darwin9-bin3.tar.gz
from research.att.com and installed per their instructions.
R (2.12.1) successfully built the "gmp" package from my modified code.
Two problems. First, every time I execute a function from gmp, I get
something like:
apply.bigz(mxg,2,max)
[1] "17" "18" "19" "20"
R(95552,0xa01f9720) malloc: *** error for object 0x1abf5674: Non-aligned
pointer being freed
*** set a breakpoint in malloc_error_break to debug
R(95552,0xa01f9720) malloc: *** error for object 0x1abf5674: Non-aligned
pointer being freed
*** set a breakpoint in malloc_error_break to debug
R(95552,0xa01f9720) malloc: *** error for object 0x1abf5674: Non-aligned
pointer being freed
*** set a breakpoint in malloc_error_break to debug
R(95552,0xa01f9720) malloc: *** error for object 0x1abf5674: Non-aligned
pointer being freed
*** set a breakpoint in malloc_error_break to debug
note that the returned values are correct for the "mxg" bigz matrix in
question.
The other problem seems to be one of search order, in that, for an
integer matrix mx,
apply(mx,2,max) works properly. But apply(mxg,2,max) fails to
"find" the bigz method and returns an error:
Rgames> apply(mxg,2,max)
Error in aperm(X, c(s.call, s.ans)) :
invalid first argument, must be an array
which is because the character matrix 'mxg' was passed to base::apply.
Any ideas? and thanks again.

Hi,
I chose to make a minor edit to the R-source matrixz.R in the gmp package (not
to be confused with the GNU gmp library which it calls).
On my Intel iMac at work, running OSX 10.6.4, it compiled just fine.
for reference, that Mac has:
%gcc -version
i686-apple-darwin10-gcc-4.2.1: no input files
and I honestly forget which version of gmplib I installed.
So, I took the R-gmp source home, where I have an Intel iMac w/ 10.5.8, and I
get the following foulup:
TheiMac:~/downloads/gmpmod:cgw-507$ ./configure
creating cache ./config.cache
checking for __gmpz_ui_sub in -lgmp... no
configure: error: GNU MP not found, or not 4.1.4 or up, see http://swox.com.gmp
I've tried installing both GNU gmp 4.3.2 and 5.0.1, same problem. And the
libraries are in /usr/local/lib, just as they are on my work iMac.
If you have doubt about your builds of gmp you can always pick the one used on
CRAN if you wish at
http://r.research.att.com/libs/
I thought it might be the compiler, so I checked:
TheiMac:~/downloads/gmpmod:cgw-508$ gcc -version
i686-apple-darwin9-gcc-4.2.1: no input files
You really meant to use --version I presume:
ginaz:~$ gcc --version
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664)
but the version usually doesn't matter - especially not on on 10.6 ;)
Any ideas what I've got set up wrong? Let me know what other system or app
diagnostics I can supply.
Well, the only useful diagnostics is the config.log - it will tell you exactly
what the error is ...
Cheers,
Simon
thanks
Carl
(I did finagle an ugly workaround, by bringing home a copy of the installed
R-gmp package. I had to go to the Library/Frameworks/... /libs/i386 directory
and swap in the original gmp.so file (from the CRAN package) to get things
mostly working))
