PATCH 1/1 Fix uninstallation of non-staged packages

Packages without $(PKG)_INSTALL_STAGING=YES currently fail to uninstall themselves with 'make pkg-uninstall'. For a real life example of the error, try uninstalling 'at' or 'dropbear'.

This patch fixes the issue by only uninstalling packages from staging if $(PKG)_INSTALL_STAGING==YES.

I understand the problem, but I don't think that the solution works. The $(BUILD_DIR)/%/.stamp_* targets are defined *outside* of the GENTARGETS_INNER macro, so $(2) in your code has no value.

The uninstallation step should probably be split in 3 different stamp
files: one for host, one for staging, one for target. Then in GENTARGETS_INNER, then <pkg>-uninstall target would depend on .stamp_target_uninstalled && .stamp_staging_uninstalled, or .stamp_target_uninstalled only, or .stamp_host_uninstalled only.

However, all the uninstall code is due to be removed/reworked when we merge the package work on Lionel. But quite some work remains to clean it up, so I can't say when it's going to be ready.

Regards,

Thomas

Oops! You are right, $(2) was empty. But $(PKG) seems to contain the package name. However, I'm having difficulties getting it to work as I'd like. Or, put another way, it's not working at all!

$(BUILD_DIR)/%/.stamp_uninstalled:

	@$(call MESSAGE,"Uninstalling")
	@echo "$(PKG)_INSTALL_STAGING: $($(PKG)_INSTALL_STAGING)"
ifeq ($($(PKG)_INSTALL_STAGING),YES)
	@echo "INSTALL_STAGING == YES"
	$($(PKG)_UNINSTALL_STAGING_CMDS)
	rm -f $($(PKG)_TARGET_INSTALL_STAGING)
else
	@echo "INSTALL_STAGING != YES"

endif

The first echo statement shows that $($(PKG)_INSTALL_STAGING) evaluates correctly to either YES or NO, but the ifeq stuff always evaluates to false... help?

Agree. But it's more work :-)

OK.
