Configuration Dependencies
|
|
--------------------------
|
|
In order to use this module, you must first install the P-Code virtual
|
|
machine. You can get this from the Pascal package or from misc/pascal in
|
|
the GIT repository. See the README.txt file at misc/pascal for installation
|
|
instructions. The correct location to install the P-code virtual machine is
|
|
at apps/interpreters.
|
|
|
|
Other required configuration settings:
|
|
|
|
CONFIG_NFILE_DESCRIPTORS > 3
|
|
CONFIG_BINFMT_DISABLE=n
|
|
CONFIG_PCODE=y
|
|
|
|
Directory Contents
|
|
------------------
|
|
This directory holds support files for the P-Code binary format. For other
|
|
binary formats, the library directory contains critical logic for the binary
|
|
format. But this is not the case with the P-code binary format; since the
|
|
binary file is interpreted, little additional support is necessary. As a
|
|
result, this directory includes only a few files needed by the binfmt build
|
|
logic and to support unit-level testing of the P-Code binary format.
|
|
|
|
Files include in this directory include:
|
|
|
|
1. This README.txt file
|
|
|
|
2. Build support file:
|
|
|
|
Kconfig, Make.defs
|
|
|
|
3. Unit test support files:
|
|
|
|
hello.pas -- Pascal "Hello, World!" source file
|
|
hello.pex -- P-Code POFF format file created by compiling hello.pas
|
|
romfs.img -- A ROMFS filsystem image created by:
|
|
|
|
make image
|
|
cp hello.pex image/.
|
|
genromfs -f romfs.img -d image -V pofftest
|
|
rm -rf image
|
|
|
|
romfs.h -- a C header file containing the ROMFS file system in an
|
|
initialized C structure. This file was created via:
|
|
|
|
xxd -g 1 -i romfs.img >romfs.h
|
|
|
|
then cleaned up with an editor to conform with NuttX coding standards.
