Problems on Mac OS X 10.3

Dear Erlang folk, I have problems using the erl_interface functions on Panther. With the binary version by Sean, the files libei.a or liberl_interface.a contain a version of strerror_r, which prevents linking as the function also appears in the system libraries. I also tried to compile the current source release. After overcomming the build problem (thanks for the Makefile patch), I'm sad to report that the c-node example from the documentation does not work. When I increase the ei_tracelevel, cnode_s.c I get the follwing output: ------------------------------ ei_epmd_r4_publish: Fri Jan 23 10:13:27 2004: -> ALIVE2_REQ alive=c1 port=3456 ntype=72 proto=0 dist-high=5 dist-low=1 ei_epmd_r4_publish: Fri Jan 23 10:13:27 2004: <- ALIVE2_RESP ei_epmd_r4_publish: Fri Jan 23 10:13:27 2004: result=0 (ok) creation=3 ei_accept: Fri Jan 23 10:13:27 2004: <- ACCEPT waiting for connection ei_accept: Fri Jan 23 10:15:06 2004: <- ACCEPT connected to remote recv_name: Fri Jan 23 10:15:06 2004: <- RECV_NAME (ok) node = e1@faui878, version = 5, flags = 255 send_status: Fri Jan 23 10:15:06 2004: -> SEND_STATUS (ok) send_name_or_challenge: Fri Jan 23 10:15:06 2004: -> SEND_CHALLENGE (ok) challenge = 1436310268, version = 5, nodename = c1@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx recv_challenge_reply: Fri Jan 23 10:15:07 2004: <- RECV_CHALLENGE_REPLY socket read failed (-1) ei_accept: Fri Jan 23 10:15:07 2004: <- ACCEPT failed erl_accept ----------------------------- could it be a problem with the cookie? Thank you, Stefan

[ex11] use of Display

Hi Joe, A silly question this time: I think I am too tired this Friday afternoon. :-) If I run something like Display=sw:start("3.1"), Win = swTopLevel:make(Display, 160, 50, 16#ffffcc), Win2 = swTopLevel:make(Display, 260, 50, 16#ffffcc), then closing any of the windows will close both of them. Is it supposed to be so? If yes, does it mean that the only one top-level window should be created per Display? It seems not so comfortable... regards, Vlad

Which isn't quite > proper, I think. I think this is my bug Vlad, so don't blame Joe for it. His second release has my smart connection patch, which I apparently made a few wrong assumptions in. I think you are right, if $DISPLAY directly contains 127.0.0.1 or localhost, or has the empty string, inet:gethostname() should only be used as one of the possible names during the xauth cookie search, but the actual connection should be to 127.0.0.1. -- Shawn.

Actually, the default hostname for RedHat Linux Workstation (others may vary) has been "localhost.localdomain" for as long as I've been using it (5 years now). Also, the actual IP address of a workstation may vary according to the information available at startup, especially if DHCP is selected. If no network connection is available, then it would not suprise me if DHCP gave you 127.0.0.1 as your IP address. > >bengt > Simon
