I think I'm missing something really stupid here.
I have libcppunit installed: (I'm using Ubuntu 12.04)
$ apt-cache policy libcppunit-dev
libcppunit-dev:
Installed: 1.12.1-4
Candidate: 1.12.1-4
Version table:
*** 1.12.1-4 0
500 http://archive.ubuntu.com/ubuntu/ precise/main amd64 Packages
100 /var/lib/dpkg/status
$ apt-cache policy libcppunit-1.12-1
libcppunit-1.12-1:
Installed: 1.12.1-4
Candidate: 1.12.1-4
Version table:
*** 1.12.1-4 0

100 /var/lib/dpkg/status
And I have a simple test:
#include <iostream>
#include <cppunit/ui/text/TestRunner.h>
#include <cppunit/CompilerOutputter.h>
#include <cppunit/TestFixture.h>
#include <cppunit/extensions/HelperMacros.h>
int main() {
CppUnit::Test* suite = CppUnit::TestFactoryRegistry::getRegistry().makeTest();
CppUnit::TextUi::TestRunner runner;
runner.addTest(suite);
runner.setOutputter(new CppUnit::CompilerOutputter(&runner.result(), std::cerr));
return runner.run() ? 0 : 1;
}
And I this is the compiler output:
$ g++ -lcppunit -o test.bin test.cpp
/tmp/ccoQDuGC.o: In function `main':
test.cpp:(.text+0x36): undefined reference to `CppUnit::TestFactoryRegistry::getRegistry(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'

test.cpp:(.text+0x227): undefined reference to `CppUnit::TextTestRunner::~TextTestRunner()'
collect2: ld returned 1 exit status
To make sure, the libraries do exist under /usr/lib
$ ls /usr/lib/ | grep cppunit
libcppunit-1.12.so.1
libcppunit-1.12.so.1.0.0
libcppunit.a
libcppunit.la
libcppunit.so
What am I missing that is causing this?
You have to tell the compiler which libraries to link to after you tell it which files to compile, i.e.
g++ test.cpp -lcppunit -o test.bin
