Question

我们有一个现有的C项目，我们想要使用vowpal wabbit。我们能够在没有vowpalWabbit的情况下生成项目的可执行二进制文件，并且运行正常。但是当我们将vowpalWabbit与现有项目链接时，生成的二进制文件会以某种方式被破坏。我们可以通过链接vowpal wabbit库来编译和运行一个独立的程序。

我们尝试以下列方式将VowpalWabbit与现有项目的makefile链接：

CFLAGS      = -g -Wall -O2 -std=gnu99 -Wno-unused-variable -Wno-sign-compare
CXXFLAGS    = -g -Wall -O2 -std=gnu++11 -fno-strict-aliasing -Wno-unused-variable -Wno-sign-compare

VW_LIBS = $(VW_HOME)/vowpal_wabbit/vowpalwabbit/libvw.la $(VW_HOME)/vowpal_wabbit/vowpalwabbit/liballreduce.la 

SRC = $(BASE_DIR)/$(VW)/$(SRC_DIR)
SRC_FILES =$(SRC)/vw_predict_test.cpp

ALL_SRC_FILES =  $(SRC_DIR)/test_main.cpp \
            $(SRC_FILES) 


bin_PROGRAMS = test 

##  binary
test_SOURCES = $(ALL_SRC_FILES)
test_LDADD = $(VW_LIBS) -lthriftnb -lthrift -levent -lpthread -lm -lssl -lstdc++  
test_CXXFLAGS = $(INCLUDES) $(CXXFLAGS)
test_CFLAGS = $(INCLUDES) $(CFLAGS)

此makefile生成损坏的可执行文件。当我们对该可执行文件执行ldd时，我们收到以下消息：

$ ldd test
        not a dynamic executable

请指导我们如何在我们的可执行文件中链接vowpalWabbit。

编辑：为了更好地理解，粘贴MakeFile的快照。

EDIT2：正如所建议的那样，我们现在使用vw_predict_test.cpp并使用g ++进行编译。我们要将liballreduce.a，libvw.a，libvw_c_wrapper.a个库链接到我们的可执行文件，因此我们执行了以下操作：

test_SOURCES = $(ALL_SRC_FILES)
test_LDADD = -lthriftnb -lthrift -levent -lpthread -lm -lssl -lglib-2.0 -lstdc++ -lz -luuid -lcrypto -lcitrusleaf -lavro -lrt -lprotobuf -lboost_program_options $(VW_HOME)/vowpalwabbit/.libs/liballreduce.a  $(VW_HOME)/vowpalwabbit/.libs/libvw.a  $(VW_HOME)/vowpalwabbit/.libs/libvw_c_wrapper.a 
test_CXXFLAGS = $(INCLUDES) $(CXXFLAGS) 
test_CFLAGS = $(INCLUDES) $(CFLAGS)

现在我们正在获得提升异常，例如：

/vowpalwabbit/.libs/libvw.a(search_sequencetask.o): In function `SequenceSpanTask::initialize(Search::search&, unsigned long&, boost::program_options::variables_map&)':
search_sequencetask.cc:(.text+0x13f6): undefined reference to `boost::program_options::options_description::m_default_line_length'
search_sequencetask.cc:(.text+0x142e): undefined reference to `boost::program_options::options_description::options_description(std::string const&, unsigned int, unsigned int)'

我们在LDADD中添加了-lboost_program_options也没有用。

在现有的C项目中链接VowpalWabbit C库
