recompiled library is ignored

in Library and Tool Development • 2 years ago

hej forum,

i am hacking a bit on zeni's animataP5 library for processing trying to implement a few new features.

i have the source in eclipse, and i am compiling the new library straight to my libraries folder, using the library template from the wiki: http://code.google.com/p/processing/wiki/LibraryTemplate

i am very new to eclipse, so i am unsure if i am doing something silly....

when i run the ant build, all looks well, the build completes and the library file is updated in my libraries/AnimataP5/ folder.

but processing is ignoring the new library???

i added a dummy function to the new library to check if it is actually active in processing, and when i call it i get a "the function xx() does not exist" error.

i can see my file is updated by the change date in the OS.

so i am thinking processing must be linking to some other file. i did a search on my computer for the library .jar, but the one in libraries is the only one i can find.

hm....

to further test i installed the recompiled library fresh on a different computer, and on this computer my dummy function exists!

any thoughts?

best,

jacob

had a chat with a friend and programmer (not a processing specialist though, so he couldn't help me all the way to a working setup)

this is his thoughts:

               
                
                 Sounds like there's a cached copy of the library hanging around somewhere, most likely in the core processing folder and not just in the sketchbook folder. That one probably takes precedence as a "global" library and is causing the issues.
                
               
is there a library cache somewhere? can i empty it?

I don't believe how low quality of the Zoho spam detector!
They give some 10 false alerts vs. 1 good (and it was worse at the start, taking every message with the word width as spam (annoying for a Processing forum! at least, they have corrected this).
Guess what? Your previous message has been marked as spam because it has the word cialis in it! Logical, as it is very common in spams... But, this word is actually in the word spe cialist! Oh man...

hi, did you restart processing after compiling the lib?

the path to a library is only read when starting processing, any newly added library while processing is running is ignored. when updating an existing library jar file, processing will load the latest update of the library when imported into a sketch.

hi,

yes i did restart processing. this makes no difference. it is still loading the (mysterious) old library, which should be non-existant??

ok, i finally figured this out. feel kind of silly now:

in the default settings in the library ant build, the destination folder and name of the library is set as "mylib" & "mylib.jar" --- while testing the ant build i compiled my animata library to this destination. this library named mylib then got loaded in stead of my animata library, as the mylib.jar contained the AnimataP5.class. of course, i could only see this when unzipping the jar, so my file searches for animata.jar left me blank.

why an older mylib/mylib.jar would be chosen over a fresh and correctly named animata/animata.jar library file is beyond me?

anyways. problem solved. now i can finally recompile libraries from source code in eclipse. yay.
