Hi all,
I am trying to build a static library from ixwebsocket project. This library can be built using cmake, I get to a stage where the library is successfully built but I can't get a package from it and I don't understand why.
All the files are stored in the following location using the correct structure for the program and creating the archive library file:
build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/ixwebsocket11-1.0/ipkg-install
This is the Makefile for openwrt:
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:=ixwebsocket11
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:=/build_mnt/ixwebsocket11
# Source settings (i.e. where to find the source codes)
# This is a custom variable, used below
include $(INCLUDE_DIR)/package.mk
include $(INCLUDE_DIR)/cmake.mk
# Package definition; instructs on how and where our package will appear in the overall configuration menu ('make menuconfig')
define Package/ixwebsocket11
SECTION:=examples
CATEGORY:=Examples
TITLE:=ixwebsocket11 library
DEPENDS:=+libstdcpp +zlib
endef
# Package description; a more verbose description on what our package does
define Package/ixwebsocket11/description
A library which hopefully works
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)
cp -r $(SOURCE_DIR)/* $(PKG_BUILD_DIR)
endef
define Package/ixwebsocket11/install
$(INSTALL_DIR) $(1)/usr/bin
$(INSTALL_BIN) $(PKG_BUILD_DIR)/ixwebsocket11 $(1)/usr/bin
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,ixwebsocket11))
The cmake file is the official one coming from the project:
