Moved the NuttX specific board files to makefiles/nuttx and added a makfiles/linux directory with sample config and board files. Created a makefiles/toolchain_native.mk file for building for Linux with the native system compiler. GCC or clang can be used by setting a flag in the file. The Linux build creates an archive file and will build the tasks as threads. Other code changes are required to support both task based and thread based builds. The NuttX source should not be required for the Linux build. The target OS (NuttX or Linux) is selected by commenting out the desired line in setup.mk Signed-off-by: Mark Charlebois <charlebm@gmail.com>

# Framework makefile for PX4 libraries
|
|
#
|
|
# This makefile is invoked by firmware.mk to build each of the linraries
|
|
# that will subsequently be linked into the firmware image.
|
|
#
|
|
# Applications are built as standard ar archives. Unlike modules,
|
|
# all public symbols in library objects are visible across the entire
|
|
# firmware stack.
|
|
#
|
|
# In general, modules should be preferred to libraries when possible.
|
|
# Libraries may also be pre-built.
|
|
#
|
|
# IMPORTANT NOTE:
|
|
#
|
|
# This makefile assumes it is being invoked in the library's output directory.
|
|
#
|
|
|
|
#
|
|
# Variables that can be set by the library's library.mk:
|
|
#
|
|
#
|
|
# SRCS (optional)
|
|
#
|
|
# Lists the .c, cpp and .S files that should be compiled/assembled to
|
|
# produce the library.
|
|
#
|
|
# PREBUILT_LIB (optional)
|
|
#
|
|
# Names the prebuilt library in the source directory that should be
|
|
# linked into the firmware.
|
|
#
|
|
# INCLUDE_DIRS (optional, must be appended, ignored if SRCS not set)
|
|
#
|
|
# The list of directories searched for include files. If non-standard
|
|
# includes (e.g. those from another module) are required, paths to search
|
|
# can be added here.
|
