i made the change:

Now I'm getting:

g++ -I. -g -DLinux -D_REENTRANT -I. -I../data -I../Thread -I../Common
-I../Network -I/home/heinrich/EPICS/cmlog/CMLOG/C++/
SACE-4.0 -c ../Network/cmlogUpIO.cc -o .obj/Linux-i386/cmlogUpIO.o    
../Network/cmlogUpIO.cc: In member function âvirtual int
cmlogUpIO::handle_input(int)â:
../Network/cmlogUpIO.cc:105: error: âstreamInPacketâ was not declared in
this scope
make[2]: *** [.obj/Linux-i386/cmlogUpIO.o] Error 1
make[2]: Leaving directory `/home/heinrich/EPICS/cmlog/CMLOG/ClientD'
make[1]: *** [linux-redhat6.0-x86-th] Error 2

I don't think it's that the compiler couldn't handle the >> operator.
It's that it can't find it or something.
I don't find any streamInPacket function - not even with grep :(
So i changed it back to fd >> packet

I'm running g++/gcc version 4.1.2

but - I also have 3.4 installed on my system.
And I've modified the makefile.config to use that.
and the result:
IT NOW WORKS!

So effectively it means that CMLOG can't be compiled with gcc version
4.1 and still need 3.4 
AARGH!!
I'm not sure what the problem is. maybe something todo with the way gcc
4.1 handles the friend operator approach.

I've done some googling about this  :)

Came up with a solution:
you need the -ffriend-injection option for g++ 4.1 and anwards.
here is the link of information:
http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/C_002b_002b-Dialect-Options.html

so in Makefile.config: (the one in CMLOG and also in C++/SACE-4.0)
I need to add -ffriend-injection into CXXFLAGS

now it works :)
Thankyou for your help!

I replaced cpThread.cc with the other file you gave me - that fixed that
problem.
