ogre2.2: patches for M1 arm processors

[iche033]

Signed-off-by: Ian Chen [email protected]

I applied the patches mentioned in #1628 (comment) with a slight tweak to the first patch.

After this I was able to install ogre2.2, build and run the simple_demo example in ign-rendering with Metal backend.

I also had to add an extra "-DCMAKE_MACOSX_RPATH=FALSE" cmake arg for ign-gazebo gui to load ogre libraries when calling dlopen otherwise I get security policy does not allow @ path expansion msgs. I didn't add that change to this PR as I'm not sure if there are other better ways to around this.

Do you know if this will apply to ultra M1 too?

no I don't know. I don't have an m1 ultra to test this.

Sorry lol I don't know why I asked dumb question. I'm seriously considering to buy ultra M1. I am more than happy to test for you guys once I get it. By the time I get it, should I create a separate issue?

I would suggest creating an issue once you are able to test this. You'll then be able to provide more info such as build errors and console output in the case that it does not work.

I have a quick question if you don't mind about this issue 👼,

How do you get this working?

Here is what I did:

1. cd /opt/homebrew/Library/Taps/osrf/homebrew-simulation/Formula
2. nano ogre2.2.rb
3. Copy/paste from the changed file on the issue here
4. Save and exit
5. brew tap osrf/simulation

Is this how you do this?

[iche033]

looks like you got pass this issue? I saw some activity in gazebosim/gz-sim#1362 that you're onto steps for building ignition. In short yes I modified the ogre-2.2.rb formula with my patch in this PR as well as adding the changes I mentioned in #1823 (comment), and then just I brew install ogre2.2 again.

currently these patches will be applied for all architectures, so we should bump the revision and rebuild bottles

I've tried to apply these patches, and believe I have done so successfully. Still doesn't compile on my M1 Macbook Pro though.

Does this set of patches apply to #1956 as well? I only have an intel mac to test with.

I was able to build ogre2.3 on M1 without this patch

[scpeters]

I've updated this branch and added some rpath fixes

bottle upload is temporarily broken, wait to rebuild
