Dear R Development Team,
I compile R-1.9.1 on AIX 5.2 under 2.9-aix51-020209, and xlf 7.1. In
order to let R compile successfully under gcc 2.9, I have to change one
C statement of file(RHOME//src/modules/X11/devX11.c) line 1768 from
"retrun FALSE" to "retrun NULL", following is C code
snapshot:
newX11Desc * Rf_allocNewX11DeviceDesc(double ps)
{
newX11Desc *xd;
/* allocate new device description */
if (!(xd = (newX11Desc*)calloc(1, sizeof(newX11Desc))))
return NULL;
/* From here on, if we need to bail out with "error", */
/* then we must also free(xd). */
/* Font will load at first use. */
if (ps < 6 || ps > 24) ps = 12;
xd->fontface = -1;
xd->fontsize = -1;
xd->basefontface = 1;
xd->basefontsize = ps;
xd->handleOwnEvents = FALSE;
xd->window = (Window) NULL;
return(xd);
}
However I got core dump while I try to use plot() from R:

Making links in per-session dir ...
If /usr/bin/netscape is already running, it is *not* restarted, and
you must switch to its window.
Otherwise, be patient ...
> x <- rnorm(50)
> y <- rnorm(x)
> plot(x,y)
Illegal instruction (core dumped)
Can anyone give me some suggestion? Thanks!
