Doesn't compile with xcode 6 about ofxbullet

[aknoerig]

Same here. This error occurs on running any of the examples. Unfortunatelty this happens inside Bullet not ofxBullet, an seems to depend on the chipset (ifdef BT_USE_SSE).
Any clues yet?

I'm on oF master, Xcode 6.1.1, OS X 10.10.2, MacBook Air.
Here's the

Looks like this might have been fixed in the bullet 2.82 release (Oct 13) vs 2.81 (Oct 12):
https://github.com/bulletphysics/bullet3/commits/master/src/LinearMath/btMatrix3x3.h

[NickHardeman]

I can take a look into this and try compiling all the libs for using 2.82 to fix this issue. However, this will lose support for windows users because of the windows libs.

[aknoerig]

This would be great! I'm trying to build them right now, but not successfully yet.
Maybe make a branch for it, so Windows users are not frustrated.

[NickHardeman]

I think I will create a release package so windows users can still use the addon. I will try to get around to it in the next couple of days.

[aknoerig]

Would love to help, do you have specific instructions somewhere? Bullet compiles fine with Xcode here. Is the rest just a matter of copy/paste/rename?

[NickHardeman]

I don't have any instructions posted, but maybe I should. I usually just compile in Release without double precision. And also for iOS. It should just be copying over the libs and the new include .h files. And then testing everything to make sure that nothing has changed.

[aknoerig]

Are you using gmake or Xcode? gmake is missing some dependencies here, not sure which ones.

Linking App_HelloWorld

make[1]: *** [../../App_HelloWorld_gmake_x64_release] Error 1

[NickHardeman]

Trying to remember...
I use Cmake to build the XCode projects and then use the XCode project to build the libs I believe.

[aknoerig]

That works, but I'm only getting 64bit debug versions, no idea how to set it to also build all the other ones..

[NickHardeman]

Using CMAKE, the flag CMAKE_CONFIGURATION_TYPES set to Release might be the answer?

[aknoerig]

Seems like this works:

cd build
premake_osx xcode4
xcodebuild -project xcode4/BulletCollision.xcodeproj/ -configuration Release

etc. :)

[NickHardeman]

Were you able to build the AllBulletDemos?
I keep getting this error

[NickHardeman]

I updated the projects to use bullet 2.82. Can you test with the latest master branch and XCode 6?

[aknoerig]

Thanks, unfortunately I'm getting the same error in btMatrix3x3 as before. :( This is at runtime, not at compile time. All standard bullet examples are running fine, though.
Could you post your build instructions somewhere, maybe the wiki here? Maybe I need to build the libs on my machine.

[NickHardeman]

Are you compiling the 2.82 libs from the google code directory? or the 2.83 libs from github. Im a bit nervous about 2.83 because it is only an alpha. I have just been using the default cmake configuration and then using the generated xcode project to build the libs.

[aknoerig]

I did the builds with 2.82 via premake -osx, and had no issues, also all Bullet demos are running fine. Since the original issue persists and I didn't have time to dig deeper, I have now switched to Windows. :) Let me know if I should make a 2.82 windows lib.

[NickHardeman]

Have you tried pulling and compiling recently? I put up a couple of patches. @prisonerjohn compiled libs for pc and made some VS2012 projects

[aknoerig]

Thanks! Commit 8a2b363 actually fixed it. :)
I also submitted a pull request already on a few other things. Consider this one closed!

[NickHardeman]

Great!
