Major departures from 3.4:
- MacOSX is now fully supported (Quartz window, audio input/output,
drag&drop, etc.). X11 is also supported (if installed on the host
machine).
- Display and sound support code has been moved out of the main
executable into runtime modules. The choice of display method
(Quartz, X11, no display at all) and sound (MacOSX CoreAudio, OSS,
NAS, Sun, no sound at all) can be changed via command-line options
when staring the VM.
- A new option `-nodisplay' has been added. It differs from
`-headless' in that the former disables display entirely (making the
memory footprint of the VM smaller) while the latter loads the
display code but does not open the Window (but allowing the
possibility of retroactively opening the window at a some later
time).
- A new option `-nosound' has been added and does for sound what
`-nodisplay' does for the display.
- Memory allocation for the heap is now dynamic, based on mmap(). The
heap will grow and shrink as the image's memory requirements change
over time. This can be disabled by giving the option `-memory
<N>[nk]' which tells the VM to use a fixed-size heap. A new option
`-mmap <N>[mk]' is provided to limit the size to which mmap() will
dynamically grow the heap (the default is 1Gbyte or 75% of your
available virtual memory, whichever is smaller). If both options
are given then `-memory' has precedence (disabling the mmap()-based
memory allocator).
- The configure option `--with-audio=...' has been removed. configure
will arrange to build as many sound modules for which it can find
the required headers/libraries.
- configure will also build as many window system support modules for
which it can find headers/libraries. The options `--without-x' and
`--without-quartz' are available to explicitly disable one or both.
