undefined reference to btAlignedAllocInternal(unsigned long, int)
Posted: Thu Aug 15, 2019 4:31 pm
Hi,
I've recently switched from Visual Studio on Windows to Ubuntu. I'm working on a project that used the LinearMath part of Bullet.
When I try to compile my program I get an undefined reference to "btAlignedAllocInternal(unsigned long, int)" error.
On windows I only reference to the LinearMath library but I figured out that the btAlignedAllocInternal may actually be defined in Bullet3Common. So I link to both of them.
Probably something I'm overlooking but I could use some help in finding out what.
My "program" looks as follows:
and I'm trying to get it to run using:
The exact error is:
I did run ./build_cmake_pybullet_double.sh and the .so files are present.
