[Netexpect-users] problem w/ send_expect. message Tcl_CreateThread() error

[Lorenzo Murillo]

Hello Eloy,
first of all, letme congratulate you for such a powerful tool you have
provided!

To Eloy and list members:
At this moment I've using the tool for some days and I can't overcome the
error message I get when trying to use send_expect command.
The error message is about *Tcl_CreateThread() error.*
I wonder if that is something common between users and there's a tricky way
to avoid it or maybe I'm missing a package or simply the program must be
run over a 32bit OS.
Whatever advise will be appreciate.
Thanks in advance,
Lorenzo


The environment is netexpect-0.20 on fedora17x64 with these packages
installed previously to install netexpect:
     yum install libpcap libdnet tcl
     yum install libpcap-devel libdnet-devel tcl-devel
     yum install arptools flex bison
     yum install wireshark wireshark-devel
Netexpect installation does not show any errors using:
     ./configure --with-tcl=/usr/lib64 -with-pcap=/usr/include
     make
     make install
And examples with spawn_network, expect_network and send_network works w/o
giving any problem.
