Hi John,

there isn't yet a simple way, it could be implemented if required
though.  Gm2 uses libpth for the create context (NEWPROCESS), switch
context (TRANSFER) and pth_select for (IOTRANSFER).  Do these low level
(create context/switch context) primitives exist in libpthread ?

Here are the actual symbols used:

pth_uctx_create, pth_uctx_make,
pth_uctx_save, pth_uctx_switch,

and type

pth_uctx_t

If these symbols exist then we could certainly change the driver to pick
up -lpthread at link time in the gm2 driver.  ./configure could also be
changed to override the choice at build time as well.

I wonder if it might be easier to build libpth and install it locally
to work around the problem for now?

regards,
Gaius
