GNU R on GNU Hurd

[Zsombor Cseres-Gergely]

Hi,

I compiled R on the Hurd, and (it seems that) everything went fine except X
support. I posted the results to R developers, but I can not answer their
questions. Probably you can. The relevant message is (hope it is not too long):

Just a quick thought....

Rather than being a problem with X11, it looks like it may be a
problem associated with dlopen() when the R_X11.so library is
explicitly loaded during the initialization. Basically, that `library'
(R_X11.so) has to resolve all of the symbols to which it refers, and
many of them are in the R executable (R.bin). Perhaps the linking and
loading mechanisms in Hurd do not export these symbols from the
application in a way that shared libraries can find them.  Or it may
be as simple as the flag passed to dlopen() not being RTLD_GLOBAL
(although that shouldn't matter).
