POHow can I build a googletest unit test using the gtest_main library with Jam?

Body
copied!<p>I am trying to build a googletest unit test for a proof of concept as a new unit testing framework that we could possibly use. In googletest, there are two ways to write a unit test: with a main, or without a main. If you do not define a main, you can link in the gtest_main library, which includes a main() function for you, saving you some time. In my environment, we use Jam to build binaries. I have gotten the binary to compile with main() in my code & by using the libgtest library, but I am looking for how to build it in Jam without the main.</p> <p>Base case (with a main() function):</p> <p>I am able to build a binary with this:</p> <pre><code>Main MyUnitTestBinary : MyClass.cpp ; LinkLibraries MyUnitTestBinary : libgtest ; Library libgtest : $(GTEST_DIR)/src/gtest-all.cc ; </code></pre> <p>Broken case (without a main() function):</p> <p>I am not able to build a binary with this. I see many errors when I attempt to link the objects:</p> <pre><code>Main sample1_unittest : sample1.cc sample1_unittest.cc ; LinkLibraries sample1_unittest : gtest_main ; Library gtest_main : $(GTEST_DIR)/src/gtest_main.cc ; </code></pre> <p>I get many Linker Errors relating to undefined reference to blah. The undefined reference seems to be coming from the testing::internal namespace, which is not part of my code.</p> <p>Any thoughts on how I can attack this, or look for more clues on the problem?</p>
