编译openwrt软件包时生成错误

Question

I want to build package for openwrt

I use this openwrt Makefile :

include $(TOPDIR)/rules.mk

PKG_NAME:=libxmpp
PKG_VERSION:=2012-06-11
PKG_RELEASE=1

PKG_FIXUP:=autoreconf

include $(INCLUDE_DIR)/package.mk

define Package/libxmpp
  SECTION:=libs
  CATEGORY:=Libraries
  TITLE:=xmpp library
  DEPENDS:=+libstdcpp
endef

define Package/libxmpp/description
 A xmpp client
endef


CONFIGURE_ARGS += \
    --disable-threads \
    --enable-static \
    --enable-shared

USE_LOCAL=$(shell ls ./src/ 2>/dev/null >/dev/null && echo 1)
ifneq ($(USE_LOCAL),)
define Build/Prepare
    $(CP) ./src/* $(PKG_BUILD_DIR)
endef
endif

define Package/libxmpp/install
    $(INSTALL_DIR) $(1)/usr/lib
    $(CP) $(PKG_BUILD_DIR)/libxmpp.so* $(1)/usr/lib
endef

define Build/InstallDev
    $(INSTALL_DIR) $(1)/usr/include
    $(CP) $(PKG_BUILD_DIR)/xmpp.h $(1)/usr/include
    $(INSTALL_DIR) $(1)/lib
    $(CP) $(PKG_BUILD_DIR)/libxmpp.so* $(1)/usr/lib
endef


$(eval $(call BuildPackage,libxmpp))

the Makefile of xmmp is as follow :

CFLAGS := -fPIC -O3 -g -Wall -Werror
MAJOR := 0
MINOR := 1
NAME := xmpp
VERSION := $(MAJOR).$(MINOR)

lib: lib$(NAME).so.$(VERSION)

lib$(NAME).so.$(VERSION): $(NAME).o
    $(CXX) -shared -Wl,-soname,lib$(NAME).so.$(MAJOR) $^ -o $@

clean:
    $(RM) *.o *.so*

but when compile the package I got this error :

Answer 1

My hunch is that it's this line:

$(CP) $(PKG_BUILD_DIR)/libxmpp.so* $(1)/usr/lib

Does resolving it to

$(CP) $(PKG_BUILD_DIR)/libxmpp.so* $(1)/usr/lib/

fix the issue?
