 | | Library use in LegOS
|
| Hi! Another technical question about LegOS: how are libraries like float handled today? Is there one copy linked into LegOS, or is each downloaded program equipped with its own copy? If I would use a different compiler, with a different set of (...) (23 years ago, 25-Mar-01, to lugnet.robotics.rcx.legos)
