compile bullet with cmake on mac osx problem

[sefiroths]

hi
i have readed Creating a project from scratch using XCode
i had this issues:

Code: Select all

"btTypedConstraint::serialize(void*, btSerializer*) const", referenced from:

 "btAlignedFreeInternal(void*)", referenced from:

then you have to include the Bullet frameworks in your Xcode project. Make sure they are built and installed like this (This is without Xcode, maybe there is some way to make them in Xcode too, I don't know):

   cmake . -G "Unix Makefiles" -DINSTALL_LIBS=ON -DBUILD_SHARED_LIBS=ON \
    -DFRAMEWORK=ON  -DCMAKE_OSX_ARCHITECTURES='i386;x86_64' \
    -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX=/Library/Frameworks \
    -DCMAKE_INSTALL_NAME_DIR=/Library/Frameworks -DBUILD_DEMOS:BOOL=OFF
   make -j4
   sudo make install

however after make -j4
i have this log:

Code: Select all

all other seems right no errors so i report only the end.
are this errors normal?

i have found that is an issue fixed, i redownload from svn and retry

This is a bug in 2.78. Do an svn checkout to get th latest version:

Code: Select all

Svn checkout http://bullet.googlecode.com/svn/trunk

That's assuming you're on Mac. Before doing that, cd into the folder you want the stuff to go in. Say "bullet-svn" maybe. Then cmake and make again and there shouldn't be an error. If you're trying to use for iPhone dev that won't work, just say and I'll explain how.

ok i have compiled correctly, and followed the tut creating from scratch, added the 5 framework generated by cmake to the project,
but still get an error:

btAlignedFreeInternal(void*) referenced from [...] symbols not found...
i started with Create a new C++ console application, using XCode from the tut, however i'll wat to use for iPhone dev after that...
thanks

do this:
trim down the src folder. The only things you need are "btBulletDynamicsCommon.h", "btBulletCollisionCommon.h", "Bullet Collision", "Bullet Dynamics", "Linear Math", and "Bullet Soft Body", and you might only need some of those. But anyway, I'm assuming you've created another folder called "src" and put only those in it. Drag that into xcode and check the copy thing. Then you have to go into your build settings (project->edit project settings->build) and search for header search paths. then put in a not recursive header search path "./src/" without quotes into "Header Search Paths", and "User Header Search Paths" Then you should be able to build.

unfortunately doesn't work for me...
over 1000 errors occurs...

when i deleted references in project of the other folders all went well, thanks!
