鏈接升壓::系統庫與OpenNI生成文件

Question

我想使用C++ Boost庫來寫一些深度數據，我形成我的Kinect到串行端口。爲了做到這一點，我需要將相應的庫與這個預先編寫的Makefile鏈接起來。我使用boost/asio編寫了一個基本程序來感受這些庫，爲了進行編譯，我必須鏈接到位於/ usr/local/lib的boost_system庫，並將頭文件包含在/ usr/local/include /促進。我想在我的OpenNI代碼中使用它，我只需要從該Makefile創建相同的連接。

# take this file's dir 
    COMMON_CPP_MAKE_FILE_DIR = $(dir $(lastword $(MAKEFILE_LIST))) 

    include $(COMMON_CPP_MAKE_FILE_DIR)CommonDefs.mak 

    # define a function to figure .o file for each source file (placed under intermediate directory) 
    SRC_TO_OBJ = $(addprefix ./$(INT_DIR)/,$(addsuffix .o,$(notdir $(basename $1)))) 

    # create a list of all object files 
    OBJ_FILES = $(call SRC_TO_OBJ,$(SRC_FILES_LIST)) 

    # define a function to translate any source file to its dependency file (note that the way we create 
    # dep files, as a side affect of compilation, always puts the files in the INT_DIR with suffix .d) 
    SRC_TO_DEP = $(addprefix ./$(INT_DIR)/,$(addsuffix .d,$(notdir $(basename $1)))) 

    # create a list of all dependency files 
    DEP_FILES = $(call SRC_TO_DEP,$(SRC_FILES_LIST)) 

    # older version of gcc doesn't support the '=' symbol in include dirs, so we replace it ourselves with sysroot 
    INC_DIRS_FROM_SYSROOT = $(patsubst =/%,$(TARGET_SYS_ROOT)/%,$(INC_DIRS)) 

    # append the -I switch to each include directory 
    INC_DIRS_OPTION = $(foreach dir,$(INC_DIRS_FROM_SYSROOT),-I$(dir)) -I/usr/local/include/boost 

    # append the -L switch to each library directory 
    LIB_DIRS_OPTION = $(foreach dir,$(LIB_DIRS),-L$(dir)) -L$(OUT_DIR) -L/usr/local/lib 

    # append the -l switch to each library used 
    USED_LIBS_OPTION = $(foreach lib,$(USED_LIBS),-l$(lib)) -lboost_system 

    # append the -D switch to each define 
    DEFINES_OPTION = $(foreach def,$(DEFINES),-D$(def)) 

    # tell compiler to use the target system root 
    ifdef TARGET_SYS_ROOT 
     CFLAGS += --sysroot=$(TARGET_SYS_ROOT) 
     LDFLAGS += --sysroot=$(TARGET_SYS_ROOT) 
    endif 

    # set Debug/Release flags 
    ifeq "$(CFG)" "Debug" 
     CFLAGS += -O0 -g 
    endif 
    ifeq "$(CFG)" "Release" 
     CFLAGS += -O2 -DNDEBUG 
    endif 

    CFLAGS += $(INC_DIRS_OPTION) $(DEFINES_OPTION) 
    LDFLAGS += $(LIB_DIRS_OPTION) $(USED_LIBS_OPTION) 

    # some lib/exe specifics 
    ifneq "$(LIB_NAME)" "" 
     OUTPUT_NAME = lib$(LIB_NAME).so 
     CFLAGS += -fPIC -fvisibility=hidden 
     ifneq ("$(OSTYPE)","Darwin") 
      LDFLAGS += -Wl,--no-undefined 
      OUTPUT_NAME = lib$(LIB_NAME).so 
      OUTPUT_COMMAND = $(CXX) -o $(OUTPUT_FILE) $(OBJ_FILES) $(LDFLAGS) -shared 
     else 
      LDFLAGS += -undefined error 
      OUTPUT_NAME = lib$(LIB_NAME).dylib 
      OUTPUT_COMMAND = $(CXX) -o $(OUTPUT_FILE) $(OBJ_FILES) $(LDFLAGS) -dynamiclib -headerpad_max_install_names 
     endif 
    endif 
    ifneq "$(EXE_NAME)" "" 
     OUTPUT_NAME = $(EXE_NAME) 
     OUTPUT_COMMAND = $(CXX) -o $(OUTPUT_FILE) $(OBJ_FILES) $(LDFLAGS) 
    endif 
    ifneq "$(SLIB_NAME)" "" 
     CFLAGS += -fPIC 
     OUTPUT_NAME = lib$(SLIB_NAME).a 
     OUTPUT_COMMAND = $(AR) -cq $(OUTPUT_FILE) $(OBJ_FILES) 
    endif 

    define CREATE_SRC_TARGETS 
    # create a target for the object file (the CXX command creates both an .o file 
    # and a .d file) 
    ifneq ("$(OSTYPE)","Darwin") 
    $(call SRC_TO_OBJ,$1) : $1 | $(INT_DIR) 
     $(CXX) -MD -MP -MT "$(call SRC_TO_DEP,$1) $$@" -c $(CFLAGS) -o $$@ $$< 
    else 
    $(call SRC_TO_OBJ,$1) : $1 | $(INT_DIR) 
     $(CXX) -c $(CFLAGS) -o $$@ $$< 
    endif 
    endef 

    ############################################################################# 
    # Targets 
    ############################################################################# 
    .PHONY: clean-objs clean-defs 

    include $(COMMON_CPP_MAKE_FILE_DIR)CommonTargets.mak 

    # create targets for each source file 
    $(foreach src,$(SRC_FILES_LIST),$(eval $(call CREATE_SRC_TARGETS,$(src)))) 

    # include all dependency files (we don't need them the first time, so we can use -include) 
    -include $(DEP_FILES) 

    $(OUTPUT_FILE): $(OBJ_FILES) 
     $(OUTPUT_COMMAND) 

    clean-objs: 
     rm -rf $(OBJ_FILES) 

    clean-defs: 
     rm -rf $(DEP_FILES) 

    clean: clean-objs clean-defs 

我說：

-I/usr/local/include/boost 

到INC_DIRS_OPTION

-L/usr/local/lib 

到LIBS_DIRS_OPTION，並

-lboost_system 

到USED_LIBS_OPTION（ASIO依靠升壓系統庫對於錯誤gen某種關合作）

我得到這個錯誤：

c++ -o ../Bin/x64-Release/Sample-NiSimpleRead ./x64-Release/NiSimpleRead.o -arch i386 -arch x86_64 -L../../Lib -L../Bin/x64-Release -lOpenNI -lboost_system 
ld: warning: ignoring file /usr/local/lib/libboost_system.dylib, file was built for unsupported file format which is not the architecture being linked (i386) 
Undefined symbols for architecture i386: 
    "boost::system::generic_category()", referenced from: 
     __GLOBAL__I_a in NiSimpleRead.o 
    "boost::system::system_category()", referenced from:

ld: symbol(s) not found for architecture i386 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 
make: *** [../Bin/x64-Release/Sample-NiSimpleRead] Error 1 

我試着加入lib目錄到我的DYLD_LIBRARY_PATH這什麼也沒做。我也嘗試創建一些共享（* .so）庫，首先使用NiSimpleRead.o二進制文件與libboost_system.a文件結合，這引起了很多錯誤。然後嘗試將boost_system.a文件本身更改爲.so，這也沒有做任何事情。任何關於此的建議都會很棒。

你的問題似乎是你只有64位升壓，並且你正在試圖創建一個通用的（32位和64位）二進制文件。請確保在32位和64位版本中安裝依賴關係，或從構建說明中丟棄此-arch i386。
