# Common Makefile for nsh command modules and utility libraries; should be |
|
# included by the module-specific Makefile. |
|
# |
|
# To build an app that appears as an nsh external command, the caller |
|
# must define: |
|
# |
|
# APPNAME - the name of the application, defaults to the name |
|
# of the parent directory. |
|
# |
|
# If APPNAME is not defined, a utility library is built instead. The library |
|
# name is normally automatically determined, but it can be overridden by |
|
# setting: |
|
# |
|
# LIBNAME - the name of the library, defaults to the name of the |
|
# directory |
|
# |
|
# The calling makefile may also set: |
|
# |
|
# ASRCS - list of assembly source files, defaults to all .S |
|
# files in the directory |
|
# |
|
# CSRCS - list of C source files, defaults to all .c files |
|
# in the directory |
|
# |
|
# CXXSRCS - list of C++ source files, defaults to all .cpp |
|
# files in the directory |
|
# |
|
# INCLUDES - list of directories to be added to the include |
|
# search path |
|
# |
|
# PRIORITY - thread priority for the command (defaults to |
|
# SCHED_PRIORITY_DEFAULT) |
|
# |
|
# STACKSIZE - stack size for the command (defaults to |
|
# CONFIG_PTHREAD_STACK_DEFAULT) |
|
# |
|
# Symbols in the module are private to the module unless deliberately exported |
|
# using the __EXPORT tag. |
