apps/interpreters README file
|
|
=============================
|
|
|
|
This apps/ directory is set aside to hold interpreters that may be
|
|
incorporated into NuttX.
|
|
|
|
pcode
|
|
-----
|
|
|
|
At present, only the NuttX Pascal add-on is supported. This NuttX add-on
|
|
must be downloaded separately (or is available in an SVN snapshot in the
|
|
misc/pascal directory).
|
|
|
|
This Pascal add-on must be installed into the NuttX apps/ directory. After
|
|
unpacking the Pascal add-on package, an installation script and README.txt
|
|
instructions can be found at pascal/nuttx.
|
|
|
|
INSTALL.sh -- The script that performs the operation. Usage:
|
|
|
|
./INSTALL.sh [-16|-32] <install-dir>
|
|
|
|
If you are using this standard NuttX apps/ package, the correct
|
|
location for the <install-dir> is apps/interpreters. That is
|
|
where the examples and build logic will expect to find the pcode
|
|
sub-directory.
|
|
|
|
Example:
|
|
|
|
./INSTALL.sh -16 $PWD/../../../apps/interpreters
|
|
|
|
After installation, the NuttX apps/interpresters directory will contain
|
|
the following files
|
|
|
|
pcode
|
|
|-- Makefile
|
|
|-- include
|
|
| `-- Common header files
|
|
|-- libboff
|
|
| `-- Pascal object format (POFF) library
|
|
`--insn
|
|
|-- include
|
|
| `-- model-specific header files
|
|
`-- prun
|
|
`-- model-specific source files
|
|
|
|
pashello
|
|
|
|
There is a simple Pascal example at apps/examples/pashello. This is the
|
|
standard "Hello, World!" example written in Pascal and interpreted from
|
|
Pascal P-Code at runtime. To use this example, place the following in
|
|
your appconfig file"
|
|
|
|
# Path to example in apps/examples containing the user_start entry point
|
|
|
|
CONFIGURED_APPS += examples/pashello
|
|
|
|
# Path to the Pascal p-code runtime interpreter module
|
|
|
|
CONFIGURED_APPS += interpreters/pcode
