[Buildroot] [PATCH v2] bcache-tools: Adding package.

[Yann E. MORIN]

Jean-Christophe, All,

On 2014-07-31 22:40 +0200, Jean-Christophe DUBOIS spake thusly:
> This patch adds the bcache-tools package to buildroot.

This line above is not needed: it is obvious this is adding the package
to Buildroot! ;-)

Since you select sub-options of util-linux, you must also select the
package itself:
    select BR2_PACKAGE_UTIL_LINUX

But you must also inherit its dependencies:
    depends on BR2_LARGEFILE # util-linux
    depends on BR2_USE_WCHAR # util-linux

But you must also inherit from the sub-options' dependencies, too:
    depends on BR2_USE_MMU # util-linux (libblkid)

And you must adapt the comment to the dependencies above, like:
    bcache needs udev /dev management and a toolchain w/ largefile, wchar

This should probably be a post-extract hook. See:
    http://buildroot.net/downloads/manual/manual.html#hooks

> +define BCACHE_TOOLS_BUILD_CMDS
> +	$(BCACHE_TOOLS_FIX_PKGCONFIG)

This should probably be:
    $(TARGET_MAKE_ENV) $(MAKE) -C $(@D) $(TARGET_CONFIGURE_OPTS)

TARGET_CONFIGURE_OPTS contains the CC= assignment.

Thus, the BCACHE_TOOLS_MAKE_ENV no longer makes sense, so you can remove
it.

Ditto:
    $(TARGET_MAKE_ENV) $(MAKE) -C $(@D) $(TARGET_CONFIGURE_OPTS) \
        DESTDIR=$(TARGET_DIR) install
