I commented out the first three lines of the (...) (20 years ago, 11-Oct-04, to lugnet.robotics.rcx.legos)

Whenever the PC program tries to transmit data, I get the following error: lnp_integrity_write(): Interrupted system call What does this (...) (20 years ago, 2-Oct-04, to lugnet.robotics.rcx.legos)

(...) Some of the functions are inline functions, that are *defined* in the header files, e.g.cputc_hex is defined in include/conio.h. With gcc you need to compile with optimization on, so that it will inline these functions correctly. Another (...) (20 years ago, 27-Sep-04, to lugnet.robotics.rcx.legos)

Can't be that the unresolved references are from the code I want to add to BrickOS, because I also tried to compile just the BrickOS-files (without the code I want to add) and the same errors appeared.
