Hi - I am stuck on a linker error with the boost_regex library. My
platform is ubuntu 16.04 LTS, arm64, NVIDIA TX1. I downloaded and built
boost 1.62.0 with the following parameters:

./bootstrap.sh --prefix=/usr/local
sudo ./b2 -d2 architecture=arm address-model=64 install

I compiled a simple program using this command line:

g++ main.cpp -I/usr/local/include -L/usr/local/lib -lboost_regex

Here is the program:

#include <boost/regex.hpp>
#include <iostream>

using namespace std;

int main(int argc, char *argv[]) {
static const boost::regex rxInt("[0-9]+");
string word = "foobar";

if(boost::regex_match(word, rxInt)) {
cout << "Integer" << endl;
} else {
cout << "Not integer" << endl;
}

return 0;
}

Here are the linker errors:

Any hints would be appreciated. Should I try to use an earlier version of
boost?

thank you!

Hi - I am stuck on a linker error with the boost_regex library. My

It looks to me like the headers you are including are from a different
Boost version to the library you are linking against - all recent
Boost.Regex versions mangle the namespace of their functions with the
Boost version number, but as these missing symbols aren't mangled, I'm
guessing you're picking up headers from an older version than 1.62.

HTH, John.

Hi John - thank you for your help! That was indeed the problem. I had
version 1.58 headers and version 1.62 libraries. thanks!
