In the Buildroot manual, it is specified that the Waf-based infrastructure supports the <pkg>_SUBDIR variable, which was not true. This patch: * makes use of this variable by changing to the given sub-directory before executing waf commands, * documents the usage of <pkg>_SUBDIR in the waf-specific section of the manual.

# WAF package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of package
|
|
# .mk files for WAF packages. It should be used for all packages that use
|
|
# WAF as their build system.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure
|
|
#
|
|
# In terms of implementation, this WAF infrastructure requires the .mk file
|
|
# to only specify metadata information about the package: name, version,
|
|
# download URL, etc.
|
|
#
|
|
# We still allow the package .mk file to override what the different steps
|
|
# are doing, if needed. For example, if <PKG>_BUILD_CMDS is already defined,
|
|
# it is used as the list of commands to perform to build the package,
|
|
# instead of the default WAF behaviour. The package can also define some
|
|
# post operation hooks.
|
|
#

# inner-waf-package -- defines how the configuration, compilation and
|
|
# installation of a waf package should be done, implements a few hooks
|
|
# to tune the build process for waf specifities and calls the generic
|
|
# package infrastructure to generate the necessary make targets
|
|
#
|
|
# argument 1 is the lowercase package name
|
|
# argument 2 is the uppercase package name, including a HOST_ prefix
|
|
# for host packages
|
|
# argument 3 is the uppercase package name, without the HOST_ prefix
|
|
# for host packages
|
|
# argument 4 is the type (target or host)
