I >noticed today that the computer didn't start with the file that I hadn't >yet compiled, but rather the one after it in the compiling order. This tells me that an object file for the routine was created even though the compilation itself failed. The object file would be either short or empty, but in both cases 'make' would have no way of knowing that it was bad, so the build would start with the next routine on the list to compile. >Later >on in the process it started giving the errors about having undefined >references to certain objects and libraries. So I ran 'make clobber' >again and it ran through the entire compilation process just fine (it >compiled in under 10 minutes). OK. >My conclusion: Every time the compiler exited due to missing software >on my system, it started back with the McIDAS component _after_ the one >that failed during the previous compile session, which had a domino >effect on libraries farther down the chain, causing them to not contain >all the objects they should have. This fits my comment above. >When I finally got all the necessary >software installed and it was able to go from start to finish without >stopping due to error, it had fully-populated libraries to work with, >and did not run into "undefined" errors. Very good. >I have one question: When I compiled the software I ran 'make mcx' >instead of 'make all', intending to later go back and compile the rest >of the components after I'd gotten the main program compiled. What >components would be added by running 'make all' ? Unidata McIDAS is composed of two SSEC McIDAS packages: McIDAS-X and McIDAS-XCD. McIDAS-XCD is a set of decoders for data in the NOAAPORT broadcast/Unidata Internet Data Distribution (IDD) system. 'make mcx' builds McIDAS-X by itself; 'make all' builds McIDAS-X followed by McIDAS-XCD. McIDAS-X has to be built first since McIDAS-XCD routines link against libraries built for McIDAS-X. >I'm not planning on >writing any McIDAS applications; I'll probably just be using it for >generating images on-demand, at least until I learn how to use it >efficiently. However, please provide me with information on compiling >the 'rest' of the package, in case I decide to do it later. After building McIDAS-X ('make mcx') you can build McIDAS-XCD at any time by running: make xcd VENDOR=-g77 >Thank you again, No worries.
