Question

我正在尝试编译一个用C ++编写的程序。我收到此消息错误：

undefined reference to `escapeXMLChars(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&)'

我搜索过并找到了这篇文章：Undefined reference to process(std::__cxx11::basic_string ... ) when compiling affdex linux sample applications

我认为发生此错误是因为我使用了GCC版本5.所以我尝试将其降级到4.8并使用gcc-4.8编译程序。但我仍然遇到这个错误，这是输出：

proc.cpp:(.text+0x4590): undefined reference to `escapeXMLChars(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&)'

我不知道为什么，我应该将gcc降级到旧版本吗？

我解决了我的问题，最后编译成功了。将我的配置调整为：

./ configure --host = i686-linux-gnu＆＃34; CFLAGS = -m32＆＃34; ＆＃34; CXXFLAGS = -m32＆＃34; ＆＃34; LDFLAGS = -m32＆＃34; ＆＃34; CC = gcc -std = c ++ 11 -D_GLIBCXX_USE_CXX11_ABI = 0＆＃34; ＆＃34; CXX = g ++ -std = c ++ 11 -D_GLIBCXX_USE_CXX11_ABI = 0＆＃34;
