R almost works if I build on AIX without the R shared library (except for
crashing
on exit and a few other anomalies). I can't get it to do much at all if I
build
with --enable-R-shlib.
For example, it won't load the X11 driver. I ran R in a debugger and traced
it
down to the point where R_load_X11_shlib successfully loads the R_X11.so
library
and calls R_init_X11. This calls R_setX11Routines in src/unix/X11.c. On entry
to this function, ptr_X11DeviceDriver = 0x2002eb20 and dev = 0x2014ba08. After
the statement
ptr_X11DeviceDriver = dev;
is executed, ptr_X11DeviceDriver remains unchanged at 0x2002eb20 !! So when I
type "X11()" at the R prompt, all I ever get is the stub message,
"the x11
device
has not been loaded".
I don't know enough about how shared libraries interact to understand why
this
pointer is apparently write-protected. I'm hoping someone here can give me
a
clue.
