Download re2 library

Question

I am using the following code to test google RE2 library

int main()
{
  int r = RE2::FullMatch("hello", "h.*o");
  cout <<" match = " << r << endl;
  return 0;
}

I am going to use the following command -

g++ -lre2 -o retest retest.cc

It compiles fine, but when I try to run a check with. / retest, it throws the following error -

error while loading shared libraries: libre2.so.0: cannot open shared object file: No such file or directory

I checked and the libre2.so.0 library exists in the user / local / lib directory and in the re2 / obj / so directory. So why this error occurs, I forget to add some details?

Answer 1

The launch sudo ldconfigdid the trick.

Answer 2

Classic trap:

g++ -o retest retest.cc -lre2 

Libraries must be the last
