|

This configuration performs a simple, minimal OS test using
|
||||
examples/ostest. This can be configurated as follows:
|
||||
|
||||
1) From a POSIX window:
|
||||
cd tools
|
||||
./configure.sh xtrs/ostest
|
||||
cd -
|
||||
. ./setenv.sh
|
||||
./configure.sh z80sim/pashello
|
||||
2) From a CMD.exe window
|
||||
setenv.bat
|
||||
|
||||
The setenv.bat will need to be updated to include the PATH to the XTRS
|
||||
hex2cmd program.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration uses the mconf-based configuration tool. See the
|
||||
"Reconfiguring" section below for information about changing this
|
||||
configuration.
|
||||
|
||||
2. The default setup for this configuration uses a windows native build.
|
||||
See the section entitled "Reconfiguring for Linux, OSX, or Cygwin"
|
||||
which will give you the steps you would need to do to convert this
|
||||
configuration to build in other, Unix-like environments.
|
||||
|
||||
3. This configuration was last verified sucessfully prior to the
|
||||
the configure to Kconfig/mconf tool using SDCC 2.6.0 built to run
|
||||
natively under Cygwin. The current build requires ca. 3.2.1 SDCC.

|
||||
You may need to first manually change the CONFIG_APPS_DIR="..\apps" definition
|
||||
in the .config file because the backslash may upset some Unix-based tools.
|
||||
|
||||
This configuration will require a recent version of SDCC (ca. 3.2.1) for Linux
|
||||
or custom built for Cygwin (see below).
|
||||
|
||||
You cannot use the default setenv.bat in these Unix-like enviroments because
|
||||
that is a Windows batch file. Use configs/z80sim/script/setenv.sh instead.
|
||||
setenv.sh must include the path to the installation location of SDCC (probably
|
||||
/usr/local/bin).
