Thanks for getting back to me on this issue. I haven't tried your
suggestions yet, however, I wonder why similar packages that don't
have the modifications you recommend seem to work they way I expect
them to.
For example, the package that installs the bridge utiliites:
package/bridge-utils/, has a Makefile that looks like this:
<snip>
I will be honest: I have some issue to find my way in the include/*.mk
files. I even might have been wrong (although adding this simple line
helped me to correct similar situations).
What I can read from the openwrt makefiles (and I may misintrepret them
; they are not that easy to follow):
* PKG_INSTALL controls the execution of "make -C yourbuilddir install"
during the package compilation (ie it executes make -C builddir && make
-C builddir install if PKG_INSTALL is defined). So effectively, it is
not related to your issue.
* BuildTarget/ipkg (in include/package-ipkg.mk) adds the compile rule,
which depends on whether Package/xxx/install is defined or not:
ifdef Package/$(1)/install
ifneq ($(CONFIG_PACKAGE_$(1))$(SDK)$(DEVELOPER),)
compile: $$(IPKG_$(1)) $(STAGING_DIR_ROOT)/stamp/.$(1)_installed
ifeq ($(CONFIG_PACKAGE_$(1)),y)
install: $$(INFO_$(1))
endif
else
compile: $(1)-disabled
$(1)-disabled:
@echo "WARNING: skipping $(1) -- package not selected"
endif
endif
The dependant rules are:
$(STAGING_DIR_ROOT)/stamp/.$(1)_installed: $(STAMP_BUILT)
rm -rf $(STAGING_DIR_ROOT)/tmp-$(1)
mkdir -p $(STAGING_DIR_ROOT)/stamp $(STAGING_DIR_ROOT)/tmp-$(1)
$(call Package/$(1)/install,$(STAGING_DIR_ROOT)/tmp-$(1))
$(call Package/$(1)/install_lib,$(STAGING_DIR_ROOT)/tmp-$(1))
$(CP) $(STAGING_DIR_ROOT)/tmp-$(1)/. $(STAGING_DIR_ROOT)/
rm -rf $(STAGING_DIR_ROOT)/tmp-$(1)
touch $$@
$$(IPKG_$(1)): $(STAMP_BUILT)
(do a bunch of stuff to generate the final package)
Thus, the conditions to have the Package/XXX/install rule executed is to
have:
* CONFIG_PACKAGE_XXX set to y (<*>)
* An existing Package/XXX/install (obvious)
And the condition to have your own install rule executed dring
compilation is:
* define PKG_INSTALL in the package Makefile
Build/InstallDev is called from the moment it is defined (right after
compilation).
