googletest SetUp Method not called

I'm using Google Test to unit test my C++ project. The getting started guide says:

If necessary, write a default constructor or SetUp() function to prepare the objects for each test. A common mistake is to spell SetUp() as Setup() with a small u - don't let that happen to you.

SetUp() is spelled correctly, but I still can't get SetUp to work. Any ideas?

#include "gtest/gtest.h"

class SampleTest : public testing::Test {
 protected:
  virtual void SetUp() { std::cout << "SetUp called." << std::endl; }
};

TEST(SampleTest, OneEqualsOne) {
  int one = 1;
  ASSERT_EQ(1, one);
}

int main(int argc, char **argv) {
  ::testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}

g++ -g -Wno-deprecated -I gtest/include SampleTest.cpp gtest/libgtest.a -o SampleTest

Output:

[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from SampleTest
[ RUN      ] SampleTest.OneEqualsOne
[       OK ] SampleTest.OneEqualsOne (1 ms)
[----------] 1 test from SampleTest (1 ms total)
