Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. build the trunk with -DUSE_DOUBLE_PRECISION=ON
2. compilation will fail due to float variables in

src/BulletDynamics/Featherstone/btMultiBodyConstraintSolver.cpp:279:10: error: cannot initialize a variable of type 'float ' with an rvalue of type 'double *' float jac1=&m_data.m_jacobians[solverConstraint.mjacAindex]; ^ ~~~~~~~~~~~~~ src/BulletDynamics/Featherstone/btMultiBodyConstraintSolver.cpp:281:10: error: cannot initialize a variable of type 'float ' with an rvalue of type 'double *' float_ delta = &m_data.m_deltaVelocitiesUnitImpulse[solverConstraint.m_jacAindex]; ^ ~~~~~~~~~~~~~~

What version of the product are you using? On what operating system?
Mac OS X, Ubuntu

I'm working on a patch.
