Hi there, I have Perl version 5.14.2 and R installed on Ubuntu 12.04 and had a problem while trying to install RSPerl. I followed the instructions on the guide in omegahat.org, and ran the commandR CMD INSTALL --configure-args='--with-in-perl' RSPerl and the following error occured:* installing to library ?/usr/local/lib/R/site-library? * installing *source* package ?RSPerl? ... checking for perl... /usr/bin/perl No support for any of the Perl modules from calling Perl from R. ***************************************************** Set PERL5LIB to /usr/local/lib/R/site-library/RSPerl/perl ***************************************************** Testing: -L/usr/lib/R/lib -lR Using '/usr/bin/perl' as the perl executable Perl modules (no): Adding R package to list of Perl modules to enable callbacks to R from Perl Creating the C code for dynamically loading modules with native code for Perl: R modules: R; linking: checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed Support R in Perl: yes configure: creating ./config.status config.status: creating src/Makevars config.status: creating inst/scripts/RSPerl.csh config.status: creating inst/scripts/RSPerl.bsh config.status: creating src/RinPerlMakefile config.status: creating src/Makefile.PL config.status: creating cleanup config.status: creating src/R.pm config.status: creating R/perl5lib.R making target all in RinPerlMakefile gcc -std=gnu99 -I/usr/share/R/include -I. -D_REENTRANT -D_GNU_SOURCE -DDEBIAN -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/lib/perl/5.14/CORE -DPERL_POLLUTE -D_R_=1 -DUSE_R=1 -DUSE_TOPLEVEL_EXEC=1 -DWITH_R_IN_PERL=1 -fpic -O3 -pipe -g -c Converters.c -o Converters.o Converters.c: In function 'fromPerl': Converters.c:323:28: error: 'sv_undef' undeclared (first use in this function) Converters.c:323:28: note: each undeclared identifier is reported only once for each function it appears in Converters.c: In function 'toPerl': Converters.c:483:12: error: 'sv_undef' undeclared (first use in this function) Converters.c: In function 'PerlAddHomogeneousElement': Converters.c:1056:7: error: duplicate case value Converters.c:1041:7: error: previously used here make: *** [Converters.o] Error 1 calling make -f Makefile.perl install Makefile out-of-date with respect to Makefile.PL Cleaning current config before rebuilding Makefile... make -f Makefile.perl.old clean > /dev/null 2>&1 /usr/bin/perl Makefile.PL Warning: -L. changed to -L/home/panayiotis/Desktop/RSPerl/src/.
