Hi,
Here is a backtrace of a program that reproduces the error. I

know so much about the problem but seems to be very weird.

Hi all,

following message
error is shown:
*** Warning: OS ERROR: checkIO: select failed: Invalid

My machine is an intel mac running Leopard (10.5). Any

highly appreciated.

Hello,
I suspect the problem is the first argument to select.
According to Apple
(http://developer.apple.com/documentation/Darwin/Reference/ManPages/man2/select.2.html),
we would get this error if this argument (nfds) is greater than
FD_SETSIZE (which is defined to 1024 on some versions of Mac OS X;
smaller than some of the FDs in the message!) while compiling
without -D_DARWIN_UNLIMITED_SELECT.
So if I understand correctly, should we add
-D_DARWIN_UNLIMITED_SELECT as a default compilation flag when building
in OS X?
Cheers,
Gustavo
If you can confirm that this is the problem, then yes as it seems to be
the only documented solution. However, with this flag, the fd sets are
probably implemented with dynamically allocated memory which is slower
than a classic bitmap (should be okay as, if I remember well, win32 does
it like that too).
Cheers,
Yves
