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:

collect2: error: ld returned 1 exit status

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

thank you!
