It might be necessary for some packages to define environment variables when calling waf build and waf install. This is done the same way as the others package types, by defining $(PKG)_MAKE_ENV in .mk. Signed-off-by: David GOUARIN <david.gouarin@thalesgroup.com> Signed-off-by: Yann E.

# 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
|
