Change default directory src for openwrt compiling package

I'm creating a package for openwrt that contains several modules. The package compiles right if the structure is:

package_name
. Makefile<s>.txt</s>
. files
. src
    + CMakeLists.txt
    + Module1
    + Module2
    + ...
    + Modulen

But if I change the name src by modules it shows me errors. I know the default structure search for src directory, but, what should I add to my Makefile.txt to change default value src to any other one?

Thank you.

Solution

  • The OpenWRt package structure can be found here. The interresting part for you is Bundle source code with OpenWrt Makefile.

    (I am afraid the Makefile should be just Makefile without txt extension. It would be helpful if you could post your complete Makefile - but I will try without it. Also please indicate the OpenWRT version you are using, the answer can be version-dependent)

    I have found in include/package-defaults.mk the following [OpenWRT 19.07.1]:

    Build/Patch:=$(Build/Patch/Default)
ifneq ($(strip $(PKG_UNPACK)),)
  define Build/Prepare/Default
        $(PKG_UNPACK)
        [ ! -d ./src/ ] || $(CP) ./src/. $(PKG_BUILD_DIR)
        $(Build/Patch)
  endef
endif

    This means to me, that either you:

    • define PKG_UNPACK in your Makefile as follows: PKG_UNPACK=$(CP) ./modules/. $(PKG_BUILD_DIR)
    • override default Prepare section as follows (or copy recursive, depending on your structure):

    .

    define Build/Prepare
        $(call Build/Prepare/Default)
        $(CP) ./modules/* $(PKG_BUILD_DIR)/
