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. Tom >From address@hidden Tue Feb 1 19:39:15 2000 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. Tom
