我试图链接我的程序可执行文件,但我一直在收到错误.
有
boost::this_thread::sleep(boost::posix_time::milliseconds(10));
在我的源代码中,链接器中产生以下错误:

我正在使用CMake,它告诉我Make发出以下命令,该命令失败:
/usr/bin/c++ CMakeFiles/rcon.dir/src/main.cpp.o -o rcon -rdynamic -L/usr/local/lib /usr/local/lib/libboost_system.a /usr/local/lib/libboost_thread.a -lpthread src/net/libnet.a src/log/liblogging.a -Wl,-rpath,/usr/local/lib
Whatever could be wrong? It is linking in libboost_thread.a?
更新
在命令行中的boost库移除undefined错误之前,移动了libnet和liblogging(我的程序的一部分,编译成静态库,因为我认为它很整洁).但是,现在我在我的代码中使用boost :: condition_variable进行编译时得到了这些,而另一个错误没有改变:

现在我有点尴尬.显然,我的升级库出了点问题.也许,我用一个版本的gcc编译它,之后我做了一个更新.这可能更新了GCC,两种版本之间存在某种形式的轻微不兼容.不过,我可能完全错了.
我删除了所有出现的提升,并取消了Archlinux存储库的提升,目前这是官方发布的最新版本.现在它应该编译.
傻我.:(
Linkonce部分(以及comdat组的新概念)是编译器发出模板实例化和外联内联函数的一种方式,而不必担心链接输出文件中的大量重复副本.例如,可能存在2个离散目标文件中的实例化模板函数的副本,其中链接器将选择一个并丢弃所有其他目标文件.为了使该情况正确链接,重要的是每个副本定义和引用完全相同的符号集.
但是,有时在使用不同的编译选项时会定义额外的符号(例如,-g或者当目标文件之间的编译器选项不同时,通常是共享库的情况)或者符号集从一个版本的gcc更改为下一个版本(我怀疑你的情况不太可能 - 编辑:好吧,让我兴奋,看起来这可能是你的愚蠢.很高兴你的问题得到了解决).这里可能会发生的是,您从非linkonce部分引用了在特定linkonce部分的某些(但不是全部)副本中定义的符号.如果链接器碰巧丢弃带有该符号的链接并保留没有该符号的链接,则会出现此错误.
我建议你重新排列对象模块的链接顺序,试图让链接器保留定义你需要的符号的部分; 特别是尝试根据它们的依赖关系将错误消息中提到的目标文件移动到目标文件列表的结尾或开头(记住目标文件在它们的命令行顺序中从左到右链接).
