How to create .provides file at pkg_info?

For Developers

Hi All,

I'm creating my own testing library, but the openwrt build system did not help me to create the libhello.provides. Any wrong with my Makefile? Please correct me. Thanks.

include $(TOPDIR)/rules.mk

# Name, version and release number
# The name and version of your package are used to define the variable to point to the build directory of your package: $(PKG_BUILD_DIR)
PKG_NAME:=libhello
PKG_VERSION:=1.0
PKG_RELEASE:=1

# Source settings (i.e. where to find the source codes)
# This is a custom variable, used below
SOURCE_DIR:=./src

include $(INCLUDE_DIR)/package.mk

# Package definition; instructs on how and where our package will appear in the overall configuration menu ('make menuconfig')
# If you use C++, need to add DEPENDS+=libstdcpp
define Package/$(PKG_NAME)
  SECTION:=libs
  SUBMENU:=Library
  CATEGORY:=Liteon
  TITLE:=Hello, Library!
  DEPENDS:=+libstdcpp
endef

# Package description; a more verbose description on what our package does
define Package/$(PKG_NAME)/description
  A simple "Hello, world!" library.
endef

# Package preparation instructions; create the build directory and copy the source code. 
# The last command is necessary to ensure our preparation instructions remain compatible with the patching system.
define Build/Prepare
	mkdir -p $(PKG_BUILD_DIR)
	rsync -a $(SOURCE_DIR)/* $(PKG_BUILD_DIR)
	$(Build/Patch)
endef

# Package build instructions; invoke the target-specific compiler to first compile the source file, and then to link the file into the final executable
define Build/Compile
	$(MAKE) -C $(PKG_BUILD_DIR) \
		CC="$(TARGET_CC)" \
		CXX="$(TARGET_CXX)" \
		CFLAGS="$(TARGET_CFLAGS) $(TARGET_CPPFLAGS) $(FPIC)" \
		LDFLAGS="$(TARGET_LDFLAGS)"
endef

# Package install instructions; create a directory inside the package to hold headers and library
define Build/InstallDev
	$(INSTALL_DIR) $(1)/usr/include
	$(CP) $(PKG_BUILD_DIR)/hello.h $(1)/usr/include/
	$(INSTALL_DIR) $(1)/usr/lib
	$(CP) $(PKG_BUILD_DIR)/libhello.so $(1)/usr/lib/
	$(LN) libhello.so $(1)/usr/lib/libhello.so.$(PKG_VERSION)
	$(LN) libhello.so $(1)/usr/lib/libhello.so.$(PKG_RELEASE)
endef

# This command is always the last, it uses the definitions and variables we give above in order to get the job done
$(eval $(call BuildPackage,$(PKG_NAME)))

I figure out the issue. I need to add Package/$(PKG_NAME)/install to trigger ipkg function. Thanks.
