and look at the description at the top. Here's an intro.
This patch makes significant changes to the configure script. It adds the
lines AC_CANONICAL_HOST and AC_CANONICAL_TARGET which detect the OS and
processor type. The configure script, knowing the OS and processor type, can
then make intelligent decisions about which CFLAGS are needed and what is the
default GUI for that platform. One of the goals of this patch is to make it
so that on all supported platforms, "configure;make" will compile cleanly.
Configure detects the target platform, but it can be overridden by using
--target=___. This is important when using one platform to generate
Makefiles and header files for another platform. See config.guess script for
the exact details of platform naming.
The defaults that are currently implemented in the modified configure script
include:
If platform is windows* or winnt*, use win32 gui.
If platform is cygwin*, use win32 gui and compile with
"-mno-cygwin -DWIN32".
If platform is macosx* or darwin*, use carbon gui and compile
with "-fpascal-strings -fno-common -arch ppc -Wno-four-char-constants
-Wno-unknown-pragmas -Dmacintosh"
If platform is macos, use macos gui.
If platform is beos, use beos gui.
If platform is amigaos, use amigaos gui.
Otherwise, use X windows gui.
everything about the installation path. There should be no more
hardcoded references to /usr/local/bochs. Instead, there are
references to @prefix@ which get replaced by the configure script
with the real prefix.
bug #429448. What is strange about this problem (on OpenBSD) is that the
compile and link goes fine, but when you execute your first readline library
function it does a dynamic link and crashes on the spot. Many autoconf
tests only compile and sometimes link the test program, but this test
compiles, links, and runs it.
--with-amigaos is allowed and sets up the makefiles correctly. It
defines a symbol called BX_WITH_AMIGAOS, which should be used in
#if..#endif constructs that are specific to amigaos.
- if --enable-cdrom is used with --with-amigaos, the cdrom_amigaos.o
object file will be added to CDROM_OBJS in the iodev makefile.
for Linux!!! I tested this using host OS kernel 2.2.14, and was able
to use telnet, ftp, irc, lynx, etc. Because it is a packet filter
solution, you aren't able to talk to the host machine, only to other
machines on the network. The patch itself is in
patches/patch.ethlinux-splite.
- remove --enable-external-cpu-memory
- Neither of these options were compiling anymore, and Kevin suggested:

in BRANCH-smp-bochs revisions.
- The general task was to make multiple CPU's which communicate
through their APICs. So instead of BX_CPU and BX_MEM, we now have
BX_CPU(x) and BX_MEM(y). For an SMP simulation you have several
processors in a shared memory space, so there might be processors
BX_CPU(0..3) but only one memory space BX_MEM(0). For cosimulation,
you could have BX_CPU(0) with BX_MEM(0), then BX_CPU(1) with
BX_MEM(1). WARNING: Cosimulation is almost certainly broken by the
SMP changes.
- to simulate multiple CPUs, you have to give each CPU time to execute
in turn. This is currently implemented using debugger guards. The
cpu loop steps one CPU for a few instructions, then steps the
next CPU for a few instructions, etc.
- there is some limited support in the debugger for two CPUs, for
example printing information from each CPU when single stepping.
For compilers (such as Microsoft VC++) which don't allow "LL" after a
constant to make it 64-bit, this patch declares all such constants as
BX_CONST64(value). Then in config.in, a switch called
BX_64BIT_CONSTANTS_USE_LL controls whether the macro puts the
LL's in or not. Configure sets the macro, if you're on a platform
that can run such things.
- check for snprintf, strtoull
- check if empty structs allowed
- check for hash_map.h
- check for blank labels as in void main () { int x=2; label: }
- if debugger, turn on disasm too
