Hello,
I am developping an R aware version of apache ant, so that you can
run
R code within an ant build script. This will make the compilation of
java source from one package that depends on java code from another
package easier, etc ...
But I can not build it on the mac platform.
If I see it correctly, you don't need native compilation for each
architecture, because the resulting code should be platform-
indemendent
(Java-classes).
correct
Also you're not really building any dynamic library to
load in R.
Embarrassingly correct
If both are correct, you can for example use configure
instead of src/Makevars to build your Java code since this a)
guarantees
that it is run only once b) doesn't trigger the SHLIB building so you
do't need a fake .so.
Thanks. This is much better than the Makevars trick, too bad this
cannot be a configure.R script that gets executed by Rscript as R is
more likely installed than bash.
Am I right in assuming that the bash script can use ${R_HOME}
It doesn't have to be bash, but yes, it can use anything that is set
by R CMD (including ${R_HOME}).
(Note that you'll also probably need configure.win - likely it'll have
to be a bit different, but ${R_HOME} is accessible as well.)

Could someone from this list try to build it.
The package is source-controlled on r-forge :
$ svn checkout svn://svn.r-forge.r-project.org/svnroot/orchestra/pkg/ant
$ R CMD build ant
# R CMD INSTALL ant_0.0-3.tar.gz
The log file from r-forge shows partial success:
http://r-forge.r-project.org/R/?group_id=504&add_log=check_x86_32_mac&pkg=ant&flavor=patched&type=00install.out
I think the relevant part of the file is this :
** arch - ppc
/Library/Frameworks/R.framework/Resources/bin/Rscript ../exec/ant.R
--installer
Java for ppc cannot run in this configuration.
Please consult documentation.
Error in .jinit() : Cannot create Java virtual machine (-1)
Calls: .jinit -> .External
Execution halted
make: *** [mylibs] Error 1
ERROR: compilation failed for package 'ant'
and this is probably related to my Makevars file.
I don't have myself access to a mac and would appreciate feedback,
so
that I can release the package on CRAN.
Many thanks in advance,
Romain
