Hi together,
once or twice a year I try to compile R (www.r-project.org) for my C760. For compilation of R gcc and g77 are needed and later the R-binary is used to compile further modules (which makes it diffult to build with a cross-compiler
My latest attempt was a native compilation based on OZ (gpe) and the native sdk + additional packages as listed in the OZ wiki.
Configuration and compilation was without problems until linking of the main R binary.
Linking failed with the following message:

gcc -Wl,--export-dynamic -L/usr/local/lib -o R.bin Rmain.o CConverters.o CommandLineArgs.o Rdynload.o Renviron.o RNG.o apply.o arithmetic.o apse.o array.o attrib.o base.o bind.o builtin.o character.o coerce.o colors.o complex.o connections.o context.o cov.o cum.o dcf.o datetime.o debug.o deparse.o deriv.o dotcode.o dounzip.o dstruct.o duplicate.o engine.o envir.o errors.o eval.o format.o fourier.o gevents.o gram.o gram-ex.o graphics.o identical.o internet.o iosupport.o lapack.o list.o localecharset.o logic.o main.o mapply.o match.o memory.o model.o names.o objects.o optim.o optimize.o options.o par.o paste.o pcre.o platform.o plot.o plot3d.o plotmath.o print.o printarray.o printvector.o printutils.o qsort.o random.o regex.o registration.o relop.o rlocale.o saveload.o scan.o seq.o serialize.o size.o sort.o source.o split.o sprintf.o startup.o subassign.o subscript.o subset.o summary.o sysutils.o unique.o util.o version.o vfonts.o xxxpr.o ../unix/libunix.a ../appl/libappl.a ../nmath/libnmath.a -L../../lib -lRblas -lg2c -lm -lgcc_s ../extra/zlib/libz.a ../extra/bzip2/libbz2.a ../extra/pcre/libpcre.a -lreadline -ldl -lm
/lib/ld-linux.so.2: undefined reference to `errno'
collect2: ld returned 1 exit status

At the moment I have no idea if this is related to R or if it is a OZ problem. Did someone encounter a similar problem before?
Many thanks, Georg
