我一直在努力编译我的项目而且我遇到了undefined reference错误.例如.:

installertest.cpp:(.text+0x9d1): undefined reference to `XmlRpcValue::makeArray()'
...
installertest.cpp:(.text+0xede): undefined reference to `dbcancel'
installertest.cpp:(.text+0xefd): undefined reference to `dbfcmd'
installertest.cpp:(.text+0xf0f): undefined reference to `dbsqlexec'
installertest.cpp:(.text+0xf2d): undefined reference to `SHA1_Init'
...

我的命令行是:

g++ -o installertest \
    -lsybdb \
    -lxmlrpc \
    -lxmlrpc_cpp \
    -lxmlrpc_xmlparse \
    -lxmlrpc_xmltok \
    -lxmlrpc_util \
    -lxmlrpc++ \
    -lxmlrpc_server_cgi \
    -lssl \
    -std=c++0x \
    ContractData.o installertest.o

objdump -T显示符号位于.so文件中.例如.:

libsybdb.so:
