undefined reference to `__gnu_cxx::__exchange_and_add(int*, int)'

Question

I am trying to build C++ code using GCC 4.3.4 on SLES-15 and getting below error.

/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld: /lib/libc.so.6:
(*IND*+0x0): multiple definition of __umoddi3
/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld: /lib/libc.so.6:
(*IND*+0x0): multiple definition of __udivdi3
/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld: LicenseFile.o: in function `remove_dots(char const*)':

LicenseFile.cpp:(.text+0x16a8): undefined reference to `__gnu_cxx::__exchange_and_add(int*, int)'

I believe these both error a linked to same root cause, as same works on SLES-11 with GCC 4.3.4.

The default gcc version on SLES-15 is gcc 7 and I have installed gcc 4.3.4 and created softlink for g++-4.3.4 and gcc-4.3.4 as g++ and gcc respectively.

Below is the linker command

and the code from LicenseFile.cpp is (see the bold line where I believe it needs the _exchange_and_add() )

std::string td::string remove_dots(const char* host_id)
{
   std::string output;
   std::string str(host_id);
   for (size_t i = 0; i < str.size(); ++i) {
       if (str[i] != ':') **output += str[i];**
   }
   return output;
}
