Ubuntu undefined reference error

Question

I'm trying to compile a program written on C++. I got this message error:

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

I've searched and found this post: Undefined reference to process(std::__cxx11::basic_string ... ) when compiling affdex linux sample applications

I assumed this error happened because I used GCC version 5. So I tried to downgrade it to 4.8 and compiled the program with gcc-4.8. But I still got this error, this is the output:

I don't know why, should I downgrade gcc to older version?

Where this function comes from? Is it's library and path to it included in your list of linked libraries? — Ternvein, Jul 14 '16 at 18:05
@MattSchuchard: I'm using a configure command like this: ./configure --host=i686-linux-gnu "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32". How do I add -std flag to this command? — PhuongLM, Jul 17 '16 at 10:27
@Ternvein: It's a function in other file, not a library function. — PhuongLM, Jul 17 '16 at 10:28

I solved my problem and finally compiled successful the program. Adjust my configure to:

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