After running configure simply run

make

Note that the compilation of Octave can take some time.

==Troubleshooting==

Another possible error occurs at the 'make' stage:
  −
  −
/usr/include/c++/3.3.1/bits/basic_string.h:228: undefined reference to
  −
    `std::basic_string<char, std::char_traits<char>, std::allocator<char> >::_S_empty_rep_storage'
  −
collect2: ld returned 1 exit status
  −
make[2]: *** [octave] Error 1
  −

This has something to do with the gcc configuration. Try compiling the following program using g++:
  −
  −
#include <string>
  −
#include <iostream>
  −
using namespace std;
  −
int main (void)
  −
{
  −
  basic_string <char>a = "thing one";
  −
  string b = "thing two";
  −
  cout << a.c_str() << endl;
  −
  return (a == b);
  −
}
  −

If it fails, then your compiler needs to be set-up differently (how?). On my machine I can compile that test program but still get the error making Octave -- how do we solve this? It has something to do with the shared C++ library versions, check for /usr/lib/libstdc++.so.6 and make sure the right version of that library is being used by gcc -- especially if you had to reinstall gcc to build the fortran support. If it still doesn't work, consider installing from the RPMs instead of compiling from source.
