Currently, the target and host flex packages do not behave the same in
terms of patching: the target variant has a patch hook that disables
building the programs (because they are not needed, and do not build
on no-MMU platforms). However, this hook is obviously not executed for
host-flex, because we really want the host flex binary to be built.
In preparation for the introduction of out-of-tree package build, it
is important that we don't do different things in the patch hooks for
the target and host variant of a given package, because the source
tree will be shared between the target and host builds.
To solve this, we introduce a --disable-program configure option,
through a patch to the flex configure.ac and Makefile.am. This patch
makes the current 0001-flex-disable-documentation.patch no longer
needed.
Furthermore, building the documentation is a PITA: flex.1 depends on
configure.ac and a few other files generated during the build. Touching
flex.1 does not work, because automake will forcibly remove the files
when its prerequisites are too old, so pre-requisites of flex.1 will
always be more recent than flex.1. So, we add a patch that adds a
--disable-doc configure option.

[yann.morin.1998@free.fr:
- rebase on-top of master,
- add patch to not build the documentation, because simply touching
flex.1 is no longer enough.
- keep install in target/, for shared builds

Subject: [PATCH] build: make it possible to disable the build of the
|
|
documentation
|
|
|
|
When targetting embedded evices, the documentation is not needed.
|
|
|
|
Building the documentation default to whether the program is built.
