Hello,
I am observing the following strange behavior when I try to
load a shared library using dyn.load() under Linux...
The library foo.so refers to a symbol in another package bar
(with shared library bar.so), I get:
dyn.load('foo.so') # error message because I forgot to load bar
library(bar) # so I fix it
dyn.load('foo.so') # works this time and everything is fine
But, if restart my R session and do it "right" the second
time there is a surprise:
library(bar)
dyn.load('foo.so') # fails
library(bar) # just to be sure?
dyn.load('foo.so) # fails again
dyn.load('/usr/local/lib64/library/bar/lib/libbar.so') # just to be really
sure?
dyn.load('foo.so')
In other words, it is possible to load foo.so, but only
after a failed attempt. If I remember to load the required
package bar I cannot load the depenent library foo.so.
Any ideas?
Thanks,
Dominick
