2. Building
|
|
|
|
|
|
2013-07-17 02:43:48 +00:00
|
|
|
Compiling requires cmake, ragel, lemon, and a recent version of clang++ with
|
2013-07-15 01:05:18 +00:00
|
|
|
c++11 support. It has only been built and tested with OS X 10.8.
|
|
|
|
|
|
|
|
|
|
mkdir build
|
|
|
|
|
cd build
|
|
|
|
|
cmake ..
|
|
|
|
|
make
|
|
|
|
|
|
|
|
|
|
This will generate bin/mpw and bin/disasm.
|
|
|
|
|
|
|
|
|
|
3. Installation
|
|
|
|
|
|
|
|
|
|
Certain configuration and execution files are generally useful. They are
|
|
|
|
|
stored in an mpw directory, which may be located:
|
|
|
|
|
|
|
|
|
|
$MPW (shell variable)
|
|
|
|
|
~/mpw/ (your home directory)
|
|
|
|
|
/usr/local/share/mpw/
|
|
|
|
|
/usr/share/mpw/
|
|
|
|
|
|
|
|
|
|
The layout is reminiscent of actual MPW installations.
|
|
|
|
|
|
|
|
|
|
mpw/Environment.text
|
|
|
|
|
mpw/Tools/...
|
|
|
|
|
mpw/Interfaces/...
|
|
|
|
|
mpw/Libraries/...
|
|
|
|
|
mpw/Help/...
|
|
|
|
|
|
|
|
|
|
4. Environment file
|
|
|
|
|
|
|
|
|
|
The Environment.text file is new; it contains MPW environment variables (many
|
|
|
|
|
of them set the library and include file locations). The format is fairly
|
|
|
|
|
simple.

# this is a comment
|
|
|
|
|
|
|
|
|
|
#this sets a variable
|
|
|
|
|
name = value
|
|
|
|
|
|
|
|
|
|
# this sets a variable if it is undefined.
|
|
|
|
|
name ?= value
|
|
|
|
|
|
|
|
|
|
# values may refer to other variables
|
|
|
|
|
Libraries=$MPW:Libraries:Libraries:
|
|
|
|
|
Libraries=${MPW}:Libraries:Libraries:
|
|
|
|
|
|
|
|
|
|
eventually, mpw will support a -Dname=value flag, so you can do something like:
|
|
|
|
|
|
|
|
|
|
# use 3.2 headers/libraries unless overridden on the command line
|
|
|
|
|
MPWVersion ?= 3.2
|
|
|
|
|
Libraries=$MPW:Libraries:Libraries-$MPWVersion:
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
5. Usage
|
|
|
|
|
|
|
|
|
|
mpw [mpw flags] command-name [command arguments]
|
|
|
|
|
|
|
|
|
|
you may also create shell aliases:
|
|
|
|
|
|
|
|
|
|
alias AsmIIgs='mpw AsmIIgs'
|
|
|
|
|
|
|
|
|
|
or create a shell script (in /usr/local/bin, etc)
|
|
|
|
|
|
|
|
|
|
/usr/local/bin/AsmIIgs:
|
|
|
|
|
|
|
|
|
|
#!/usr/bin/sh
|
|
|
|
|
|
|
|
|
|
exec mpw AsmIIgs $@
|
|
|
|
|
|
|
|
|
|
mpw looks in the current directory and then in the $MPW:Tools: directory
|
|
|
|
|
for the command to run. The MPW $Commands variable is not yet supported.
