Mingw: - "msys-base" is the package name when "MSYS Basic System" is mentioned in the guide - I didn't select any other options and the "pi.bat" failed 'cos it couldn't find gcc TortoiseSVN: - no problems Z88dk: - cheated and installed a backup of an old version whoami and hostname commands: - "mingw-get.exe install coreutils" gave an error "unknown package" => msys-coreutils already installed? But "hostname" already worked! Z80 target for Binutils: - I had to create the "c:\MinGW\msys\1.0\local\bin" folder Build Environment batch files: - the third line looks iffy! SET Z80_OZFILES=C:/Programs/z88dk/lib SET ZCCCFG=C:/Programs/z88dk/lib/config/ PATH %PATH%;C:/Programs/z88dk/bin Z88dk SP1 sprite library: - skipped this since I restored from a working backup Building the Spectranet sources: - fine
