The history document of libgloss seem to be stripped from the current newlib, so be welcome to search the 'embed' docs from the GNUPro-96q3 sources on the CDROM with the O'Reilly book "Programming with GNU Software". > So, if i just modify the read()/write()/sbrk() functions in > newlib-src/newlib/libc/sys/h8300hms, then rebuild, would > that work? Yes, and please remember to split the 'syscalls.c' into smaller parts... > Also, when configuring newlib says libgloss is not supported > for the h8300-hms, what does that mean? The configure stops > at that message too. It simply means that it cannot configure there for h8300-hms. Please try the following in the 'newlib-1.8.2' main dir : 1. $ less configure.in 2. Search for "h8300" with "/h8300", and you will see the 'noconfigdirs' list for h8300 and h8500. The list includes the 'target-libgloss', which means that 'libgloss is not supported' for h8300 or h8500. The 'noconfigdirs' definition includes also 'target-libio' and target-libstdc++, so if you remove these from the 'configure.in' in the GCC sources, you will get the C++ libs built for H8/300[HS] too...
