FYI: Still running into problems in grDevices using
/data/prj/cran/${RELEASE}/configure --disable-lto --prefix=/opt \
--disable-R-shlib --enable-R-static-lib \
--with-cairo=no --with-libpng=no --with-jpeglib=no
--with-libtiff=no \
--with-readline=no --with-x=no
So, Simon - very interested in your environment and whether make
completes successfully - to the end.
p.s. - I am a bit surprised about the messages below (line 4) because I
am assuming that shared libraries are not being used (with
--disable-R-shlib --enable-R-static-lib ).
fyi - from memory - but my expectation is that it has to do with the
-bexpall and an incorrect library search path being inserted. The symbol
is in /opt/lib/ppc64 archives:
root at x069:[/opt/lib/ppc64]nm -X64 -Ae *.a | grep __register_frame_info_table

But these are not being found, rather specified. Somehow the default
behavior of gcc (i.e., the flags it passes to ld are being overruled).
It will take time, but I shall find them.
