! [antonin] MJ2 module:
|
||||
- Add two components to mj2.h: meth, enumcs.
|
||||
- Define or reset all components of mj2_cparameters_t before its usage.
|
||||
- Add argument '-D prec' to frames_to_mj2.c and use the precision in mj2_convert.c (solves Issue 49).
|
||||
* [antonin] move 'KK' definition from rs.h to rs.c to prevent duplicate symbol error when building jpwl with autotools.
