Addon dependencies include order in make

[HalfdanJ]

I just added an dependency in ofxCv to ofxOpenCV, but in make based build systems this has an issue, ofxCv gets included before ofxOpenCV in the linking phase, it should be opposite, dependencies should get included first.

I've tried to move the dependency includer in config.addons.mk around a bit, but haven't found a place where it works.

[arturoc]

what error do you get? i'm trying adding a dependency from ofxCv to ofxOpenCv and it's working fine for me. also adding ofxopenCv both as a dependency and in addons.make

[HalfdanJ]

Errors like these (i've removed ofxOpenCV from addons.make)

@HalfdanJ are you still getting these issues? I haven't been able to reproduce them.

which is actually weird since I'm building for ARM. for some reason x86 library is included in the linker

never mind the comment above. I think I figured out the problem; it's related to the link order. As a test I renamed opencvimgproc.a to opencvyimgproc.a and opencvcore.a to opencvzcore.a to change the link order and it compiles. I wonder the link order can be specified in addon_config or somewhere to fix this issue
