regex_search.hpp:56:对`boost :: re_detail_106100 :: perl_matcher的未定义引用 [英] regex_search.hpp:56: undefined reference to `boost::re_detail_106100::perl_matcher
问题描述
从boost 1.58更新到1.61后，链接失败，并显示以下错误:
After updateting from boost 1.58 to 1.61, linking fails with the following error:

我使用cmake像这样链接到Boost:
I use cmake to link against boost like this:
find_package(Boost COMPONENTS chrono system filesystem thread regex random REQUIRED)
target_link_libraries (myprog
${Boost_REGEX_LIBRARY}
)
我搜索了boost的更新日志，但是找不到可能导致cmake链接失败的特定内容.就像我说的那样:1.58可以完美地工作.
I searched the changelog of boost but could not find anything specific that might cause the cmake linking to fail. Like I said: it works perfectly with 1.58.
libboost-regex1.61.0损坏了还是链接改变了?
Is libboost-regex1.61.0 broken or did the linking change somehow?
更新:2016年11月14日: Boost的变更日志显示名称空间已从"re_detail"重命名为"BOOST_REGEX_DETAIL_NS".
Update: 14.11.2016: The Changelog of Boost shows that the namespace was renamed from "re_detail" to "BOOST_REGEX_DETAIL_NS".
我使用的是Kali Rolloing版本，在我看来，installedboost lib 1.61与boost 1.61源不匹配.我将尝试手动安装lib，并检查是否可以解决问题.
I use Kali Rolloing release and it seems to me that the installedboost lib 1.61 does not match the boost 1.61 source. I will try to install the lib manually and check if this solves the problem.
我更新为1.61，然后更新为1.62.问题仍然存在. 我检查了链接器命令，并确保该行的末尾存在"-lboost_regex". 我只能想到两个问题:
I updated to 1.61 and afterwards to 1.62. To problem remains. I checked my linker command and ensured that "-lboost_regex" is present at the end of the line. I can only think of two problems:
- 我的系统有一个旧的boost_regex库，尽管cmake宣布使用1.62，但cmake仍使用该库链接它.
- 更新标头时，Kali中的boost_regex库已过时.
我检查了我的图书馆，它们看起来不错:
I have checked my libraries and they seem to look good:
newgen@kali:/usr/lib/i386-linux-gnu$ ls -al | grep boost | grep regex
-rw-r--r-- 1 root root 2390702 Nov 12 19:46 libboost_regex.a
lrwxrwxrwx 1 root root 24 Nov 12 19:46 libboost_regex.so -> libboost_regex.so.1.62.0
-rw-r--r-- 1 root root 1107284 Nov 12 19:46 libboost_regex.so.1.62.0
更新:09.12.2016: 我没有导出共享对象，但是来自boost开发人员的提示指出了包装中的混乱.我试图查看当前的库，我猜想lib是v1.58，而标头是v1.62.
Update: 09.12.2016: I am no export on shared objects but a hint from the boost developers points to a mess up in the packaging. I tried to look into the current library and I would guess that the lib is v1.58 while the headers are v1.62.

推荐答案
boost 1.61(及更高版本)是使用较新的编译器进行编译的，这些编译器使用_GLIBCXX_USE_CXX11_ABI = 1 .. heh ABI.这意味着-std = c ++ 11 std::basic_string...变为std::__cxx11::basic_string...(对于std :: list也是如此;参见
The boost 1.61 (and higher) are compiled with newer compilers, which use the _GLIBCXX_USE_CXX11_ABI=1 .. heh ABI. Meaning that for -std=c++11 std::basic_string... becomes std::__cxx11::basic_string... (and likewise for std::list; see the gcc Dual ABI documentation).
由于您的链接器错误声称缺少一个包含std::string的符号(它是std::basic_string<char,std::char_traits<char>,std::allocator<char>>的缩写)，因此您正在使用过旧且使用ABI 0的编译器进行编译，或者您甚至在显式地进行编译与-D_GLIBCXX_USE_CXX11_ABI=0.
Since your linker error claims there is a missing symbol that contains std::string (which is short for std::basic_string<char,std::char_traits<char>,std::allocator<char>>), you are either compiling with a compiler that is too old and uses ABI 0, or you are even compiling explicitly with -D_GLIBCXX_USE_CXX11_ABI=0.
无论哪种方式，在您的CXXFLAGS中添加-D_GLIBCXX_USE_CXX11_ABI=1都可以解决问题.
Either way, adding -D_GLIBCXX_USE_CXX11_ABI=1 to your CXXFLAGS should solve the problem.
