Kurt,
I use survival4_1.0-2. Now, I tried the same experiment on my
Solaris2.4 system, with exactly the same R-survival4 setup, and
got:
> library(survival4)
Autoloading required package: splines
> coxph(Surv(c(1,2,3,4), c(1,1,1,1)) ~ c(1,0,1,0))
ld.so.1: /export/home1/local/R-0.60.1/bin/R.binary: fatal: relocation
error: symbol not found: S_alloc: referenced in
/export/home1/local/R-0.60.1/library/survival4/libs/survival4.so
Killed
which, besides ???, leads me to a question about S_alloc:
I haven't found any documentation about the proper way to
allocate/free memory in user-supplied C functions. I have
used the standard C routines malloc and free. It works, but my
functions are very slow when run under R, compared to when called
from a standalone main program. Any suggestions?
