weirdness with strokeCap()
Dec 8th, 2005, 4:16am  
Hi,

Downloaded 0097 recently, started messing with some of my sketches. Some which use OPENGL break straight away, with this error message -

RuntimeException: strokeCap() not available with OPENGL

The weird thing is that the strokeCap method is not used anywhere in my sketch..

can you please post a sketch that reproduces the problem?

this has been fixed in 0098 (or was it 0099?)

I have had exactly the same problem: sketches that work in version 0085 now return the 'stokeCap( ) not available' error message, even when it is not used.

I have tried downloading versions 0096, 0098 & 0099  but all have the same problem. The sketches only work on 0085...

weird, are you sure you're using 107? that shouldn't be possible anymore but i guess i'll figure out a different way to fix it.

Re: weirdness with strokeCap() [propably SOLVED]

the same problem occured to me yesterday. i finally was able to trace it down to the"AIExport.jar" library, which i had put into the proper library hierarchy within the sketch folder. if this is present, starting opengl (and some other things as well) fails as described above. best of all: this happens even if the library is NOT imported. pretty messy and not this obvious...

what version of the aiexport.jar file are you using (from where?) i'd like to take a look. i wonder if it includes parts of core.jar or static initializers that are causing trouble.

it's the one that is linked in the reference->libraries section here. the date of the classes in the jar is 2005-09-16. and yes, indeed, it does include parts of core.jar, lots of it. consequently the lib should propably be moved to the deprecated/incompatible section below.

nonetheless, i wonder why the processing.core.* classes in the jar seem to get accessed during compilation even though the library has not been imported into any of the sketch files.

yikes, yes, we'll move the lib unless it gets updated. that's a naughty way to make a library, i guess that'll be something to add to the howto.txt for libs. no wonder we're having so much aiexport trouble.

as for why it's being included, it sounds like the classpath code has gotten a little promiscuous. i'll try and see if i can reproduce it here.

fixed with new version of aiexport (see status section of the board) but filed a bug to make sure that other libs can't overwrite things like processing.core classes:
