ODE 0.16.6 Released

[Oleh Derevenko]

Hi All,

So far, I've made 0.16.6 release. I have merged all changes to make/build-files and the recent changes to multi-threaded execution.

Thanks, our current plan is to integrate this new version it in our software in 1-2 months at most.

While testing the multi-threaded boxes I once had a NULL-pointer exception when the demo application window was in background and I clicked on it to activate. But it was a release build without debug symbols and I could not see what the reason was. And it did not happen anymore after that.

Okay, I've been running a demo in x86 and x64 for several hours, going back to it once in a while and I did not get any issue.

I have rebuild 0.16.6 and maybe is not 100 % ABI binary compatible. Here
is the report attached. Let us see if it arrives to the list.

Hi Leopold,

This thing lists internal symbols that are private in the library. They are visible in ELF format since they are declared "extern" but they, actually, are not the library exports. You should compare only what is declared in public headers under include/ode/

So, can I trust that it is binary compatible, right?

I have tested all the debian packages that use ode and work. The only
that has failed has been dart, but it has failed a test.

Cheers,

If you want to compare, you need to check out the header files from the old release you had, checkout the headers from this new release into another folder, and then perform file by file comparison to see what declarations were added/removed and if these changes would preserve compatibility.

Done!!!

I have used abidiff and although it shows removed functions, all are not
exposed public, so I guess it is compatible.
