Subject Re: Celix - eCos - embedded devices

Hi Deroo,

Like Sascha says, CMake has pretty good cross compile support. I am not
familiar with Ecos, but I think it should be fairly simple to get it

The biggest challenges probably will be library loading and getting Apache
APR working.
Library loading: Celix relies on libdl for loading/unloading libraries,
Ecos has to have something similar
Apache APR: Celix uses APR as runtime abstraction and uses a memory pool
model. Potentially this may interfere with the real time behaviour of Ecos.
But on the other hand, since APR is an abstraction, it might as well be
interesting to see if Ecos can be added to it (this might also be a nice
fix if Ecos uses a different loading model.
We do use a small subset of APR, so when crosscompiling it, quite a lot of
features can be ignored/disabled.

In the past a colleague worked on compiling Celix using buildroot, I should
have some information on that somewhere. If you are interested I can look
it up and mail to you. If I am correct, he made Celix working on an ARM
based system and used Buildroot for crosscompiling everything (APR, Celix
and the other dependencies).

Hope this helps, if you have any other questions, don't hesitate to ask!
