dear rooters
I am trying to convert the hclient.C and hserv.C examples into stand
alone
c++ programs. unfortunately i get the following compiler message
(linux or sgi both using gcc)
b0rv04:~/bin/root/mystuff > make hclient
g++ -fsigned-char -fPIC -I/usr/people/wenzel/bin/root/include -c
hclient.cxx
hclient.cxx: In function `int main()':
hclient.cxx:70: `hpx' undeclared (first use this function)
hclient.cxx:70: (Each undeclared identifier is reported only once
hclient.cxx:70: for each function it appears in.)
*** Error code 1 (bu21)
any help is appriciated
thanks Hans

// - Execute in the second and third windows: .x hclient.C
// If you want to run the hserv.C on a different host, just change
