ControlP5 recompiling
Feb 27^th, 2009, 2:59am

Hi !
I have been trying to recompile the Controller.java class of ControlP5 to include a new set3dPosition function. The goal is to be able to set the z coordinate to move a text in a 3D space. However I have a lot of trouble trying to recompile the file and update the jar file. How can we do this easily ? It seems not to recognize the processing classes, and the other classes of controlP5, even if i put the classpaths... how do we handle that please ?

hi, the following works for me on osx.
you can checkout the svn repository of controlP5. after downloading a copy of the current version of controlP5:

ANT-COMPILE
navigate to folder sojamop5/trunk
in there you will find folder buildFiles which contains an ant file called buildControlP5.xml
navigate back to trunk, create a folder libs and put a copy of core.jar (the core sources of processing) in there

go to trunk/buildFiles and use the following command from your command line:
Code:


ant -f buildControlP5.xml

your compiled controlP5.jar file will be located in
trunk/tmp/controlP5/library/controlP5.jar

JAVAC-COMPILE
(the command line below applies to osx, when using windows, the : as classpath separator has to change to ; )
navigate to folder sojamop5/trunk
in your command line tool execute the following commands. make sure folder trunk/tmp and folder trunk/tmp/build exists. then proceed with the following
Code:


javac -classpath "./src/controlP5:./libs/core.jar" -d ./tmp/build ./src/controlP5/*.java ; cp src/controlP5/*.gif tmp/build/controlP5 ; cd tmp/build ; jar cf controlP5.jar controlP5

the controlP5.jar will be located in trunk/build

hope this helps. the ANT-COMPILE version should be the preferred way to compile controlP5. i do use the buildFast.xml ant-file from within eclipse though to compile controlP5.

best,
andreas

Thanks a lot for taking the time to help me out. I'm completely new to the concept of svn repository though. I installed tortoiseSVN and I wasn't able to create a folder libs on the server because it asked me for a login / pass I don't have.

However I did manage to get a copy of the whole trunk file. Then, locally, I made a change of the Controller.java file, then created the libs folder and put the core.jar processing file there.

Then I created the tmp/ and tmp/build/ folders. I don't have my own server so I excluded the ant compilation. I did the javac though. Turns out I have the same 100 errors I had before while I try the first :

javac -classpath "./src/controlP5:./libs/core.jar" -d ./tmp/build ./src/controlP5/*.java on the command line

errors include :

"cannot find symbol"(class PApplet)

and

".\src\controlP5\Label.java:198: operator + cannot be applied to <nulltype>,int theApplet.rect(position.x, position.y, _myImage.width +_myControllerStyle.paddingRight"

any clues ?

Almost !!

Thanks to you I succeeded in building the jar file. It was because of the ; !!! However the cp command couldn't be recognized. I supposed this meant "copy all the gifs from source controlP5 to tmp controlP5 so I did it manually and the images were in the folder along with the class files before building the jar.

But when I replace your controlP5 jar by mine I get this error :

Uncaught error fetching image: java.lang.NullPointerException at sun.awt.image.URLImageSource.getConnection (URLImageSource.java:99)[...]

Do you know why ?

you get this error, because the gif files are not included in controlP5.jar. i am not sure what the windows equivalent to cp (copy files) is, so i use the manual copy procedure in the example below.

Code:


javac -classpath "./src/controlP5:./libs/core.jar" -d ./tmp/build ./src/controlP5/*.java ;

copy the .gif (with 0.3.14 there are 4 gif images in src) files manually into tmp/build/controlP5 then continue with.

Code:


cd tmp/build ; jar cf controlP5.jar controlP5

works for me.

I just fetched the most recent version from the svn repository and had some trouble building. The ant file buildControlP5.xml did not work for me: while everything compiled okay, I think there was some kind of namespace error or something, because when I copied the resultant jar into my Processing libraries directory, I would get a "does not exist error" when trying to load it up in a sketch.

When I ran buildFast.xml from Eclipse, however, everything worked fine.
