Your version should be OK.

OK, we will see if this is needed for the McIDAS build.

That was not the error.

That was not the error either.

Thanks, this helped get things going quickly. I logged in and found a
couple of things that probably were causing the failure:
o the CFLAGS environment variable in .cshrc was set to '-o'; it should
be set to '-O'. I made this change and then did a 'source .cshrc'
o it turns out that the 'make clobber' was not cleaning up in the
mcidas7.6/tcl/unix directory. The reason that it wasn't was that the
configure step had not gotten far enough to create a Makefile, so
there was nothing a 'make distclean' could do. I cleaned up by hand
by:
cd mcidas7.6/tcl/unix
rm config.cache
rm config.log
there was a file named -DNDEBUG in the this directory also;
I removed it:
rm -- -DNDEBUG
After making the above changes I did the following:
cd ~/mcidas7.6/src
make clobber
make mcx
As I write this make is compiling C modules for the McIDAS library. I
will wait until some executables get compiled and linked to see if
there is a need to do anything extra with the '-lm' flag.
<after about 15 minutes>
The netCDF contained in the distribution has been built, and the Tcl/Tk
stuff is currently being compiled. So far, everything is going smoothly.
<about 5 minutes later>
OK, McIDAS executables are being built with no problems. I am
stopping the build at this point <CONTROL-C>. You should continue
the build by:
<login as 'mcidas'>
cd mcidas7.6
make clobber <- optional if you want to see a clean build
from start to end
make mcx
make install.mcxall <- after the build has finished, you install it
You will then need to continue with the configuration of McIDAS-X as is
discussed in the online McIDAS documentation.
>Thank you!
You are welcome. I am guessing that an initial 'tclconfig' attempt
went bad and created the mcidas7.6/tcl/unix/config.cache file. This
saves settings from/for a configure run. Each time you tried to start
the compile, a configure would be kicked off in the mcidas7.6/tcl/unix
directory, but new settings would not be generated since config.cache
existed. Removing it and straightening out the CFLAGS environment
variable enabled configure to run correctly and so produce a Makefile.
By the way, the connection from here to Hawaii is very good, and your
machine is apparently reasonably fast, so this build should not take
too much time.

Xinli,
One thing I forgot to mention in my previous email. I did a 'top'
as the user 'mcidas' and note that an invocation of 'control-panel'
was taking up about 99% of the CPU:
9:30am up 1 day, 7:19, 2 users, load average: 1.03, 1.48, 1.68
63 processes: 60 sleeping, 3 running, 0 zombie, 0 stopped
CPU states: 99.6% user, 0.3% system, 0.0% nice, 0.1% idle
Mem: 257048K av, 249252K used, 7796K free, 46192K shrd, 141396K buff
Swap: 72256K av, 112K used, 72144K free 56728K cached
PID USER PRI NI SIZE RSS SHARE STAT LIB %CPU %MEM TIME COMMAND
21609 root 13 0 1620 1620 1224 R 0 99.4 0.6 51:23 control-pane
31967 mcidas 1 0 720 720 552 R 0 0.5 0.2 0:00 top
I noticed this on my RedHat 5.2 machine when I did the following:
o logged on as root
o ran control panel
o exited the session without exiting control-panel
For some reason the control-panel routine keeps running even when root
logs off (or if became root and then ran control panel). This is some
sort of a bug that goes away in RedHat 6.x.
Your machine will run faster if you kill that renegade control-panel
invocation:
<become root>
kill -9 21609
This will make the McIDAS build go lots faster, so I highly recommend it.
