[distcc] RE: Re: Re: distcc and cl.exe (MS Visual compiler)

Hello Sebastien,

THANK YOU VERY MUCH SEBASTIEN!!!! It was the right solution!
On the server side, I have to do "export TMPDIR=c:/temp" and it works!

Unfortunately, if I set TMPDIR to c:/temp in windows environment variables,
it doesn't work because in cygwin TMPDIR is translated to /cygdrive/c/temp.
Then I have to write "by hand" "export TMPDIR=c:/temp" each time before
writing "distccd --daemon". I think I will patch tempfile.c as you
suggested.

Now I have another problem, that I guess, will be easy to fix. I'm using
Ethereal (a free Ethernet sniffer) to sniff distcc packets (tcp port 3632) ;
then I can see if packets are sent throught the network.

If I set
   export DISTCC_HOSTS=remote_host
then data are sent to my remote host (I seen dumps in ethereal).

If I set
   export DISTCC_HOSTS="localhost remote_host"
I don't see any trace in ethereal (the whole project is compile locally).

If I set
   export DISTCC_HOSTS="remote_host localhost"
then the project seems to be compiled only on the remote host (I see traces
in ethereal and compilation is slow).

If I set
   export DISTCC_HOSTS="invalid_host remote_host"
where invalid_host is an invalid host name, then the project compiles on my
remote host (I see traces in ethereal).

Then it seems that only the first valid host in DISTCC_HOSTS is taken into
account. Did I missed something in the syntax?

Thanks,
Frédéric Paolucci

I set
   export DISTCC_HOSTS="localhost br044test"    (br044test is my remote
host)

Here's the log file for compiling 4 files (a.c, b.c, c.c and d.c) ; note
that "br044test" is never displayed in the log file. It's the same thing if
I compile a big project...
