Hard to see, but I think it's to do with the parallel execution on the sort function. Make sure USE_PARALLEL_PROCESSING is defined (or try explicitly undefining it).

This is related to the distro provided libbullet (v3.17, built with "-DUSE_DOUBLE_PRECISION=ON").
Unfortunately most modern Linux distributions are shipping versions of libbullet with support for double precision enabled.
Do you have a workaround for this ?

[fallahn]

Interesting - AIUI gcc < 15 doesn't support parallel execution policies, I was under the impression it should be OK with 15 (in which case this line may need to be updated).

WRT libbullet presumably you can define BT_USE_DOUBLE_PRECISION which will then typedef btScalar as double turning btRigidBody::setDamping(float, float) into btRigidBody::setDamping(double, double)

defining BT_USE_DOUBLE_PRECISION results in:

🤔 Hard to say. I mean if you're linking an external lib it should just work regardless of how that lib was built. Perhaps:

• Try creating a manual typedef for btScalar instead of using the define
• The build is somehow getting mixed up with the bullet headers in the crogine/extlib dir
• The build is confused by the fact the game uses bullet 2.83 not 3.x

If all else fails try rebuilding bullet from source without the high precision define (the game works fine with regular precision)

I agree but it seems different with bullet which defines some stuff at the compile time.

* Try creating a manual typedef for btScalar instead of using the define

Unfortunately that did not help.

* The build is somehow getting mixed up with the bullet headers in the crogine/extlib dir

I nuked the extlib folder already.

• The function btTransform::setFromOpenGLMatrix(const btScalar* m) therefore expects a const double*.
  Meanwhile, cro::Transform::getLocalTransform() (from crogine) uses a 4×4 float matrix.

One Option could be to convert the float matrixes to double ...

const auto& mat = entity.getComponent<cro::Transform>().getLocalTransform();
btScalar dmat[16];
for (int i = 0; i < 16; ++i)
{
    dmat[i] = static_cast<btScalar>((&mat[0][0])[i]);
}
transform.setFromOpenGLMatrix(dmat);

... but this costs performance and better options probably exist.

* The build is confused by the fact the game uses bullet 2.83 not 3.x

If all else fails try rebuilding bullet from source without the high precision define (the game works fine with regular precision)

• The game can be built and runs fine with bullet 3.17 (regular precision)
  The problem still is that many modern Linux distributions build bullet with double precision.

• Using a locally bundled bullet with (regular precision) could be an option to workaround this issue

My goal is to create a package for your loveley game Super Video Golf for the openSUSE Linux distributions :-)

[fallahn]

Aw thanks :D

Are you using CMake? If bullet has a CMake file I can use FetchContent to automatically pull and build bullet when the game is built - possibly even link it statically so there's no extra libs to distribute.

[mnhauke]

All package builds for openSUSE on OBS (Open Build Service) run in VM/chroot environments with only the required packages installed but without external network access.

Dependency handling with CMake's FetchContent still works since I can download all external dependencies in advance and then use FETCHCONTENT_SOURCE_DIR_<uppercaseDepName>.

Statically linking would be preferred to not interfere with the distro provided libs.

[fallahn]

OK, if I get a mo this week I'll look into it. It might actually help with the Steam Deck build too.

[fallahn]

So I've had a quick look at this - it seems the cmake files for bullet are a bit old and don't work well with FetchContent. 😔

Unfortunately, while I'd love to see golf packaged for openSUSE, I don't have the time to concentrate to fixing this right now, sorry. If you come up with a solution in the interim do let me know and I'll happily merge it (if it's suitable), but otherwise I'm going to put this on hold.

[mnhauke]

Thanks for checking it out. No worries - I'll give it a try myself.
