[pkg-boost-devel] Bug#516879: libboost-test1.34.1: Can't find main; no gcc4.2 unit_test files?

[Ross Boylan]

Package: libboost-test1.34.1
Version: 1.34.1-14
Severity: normal

Following the directions at file:///usr/share/doc/libboost-doc/HTML/libs/test/doc/components/utf/components/test_case/auto_register_facility.html create foo.cc:
---------------------------------------
#define BOOST_AUTO_TEST_MAIN
#include <boost/test/auto_unit_test.hpp>

BOOST_AUTO_TEST_CASE(test1){
  BOOST_CHECK(1);
    }
-----------------------------------
When I try to build:
$ g++  -o foo.out foo.cc -lboost_unit_test_framework
/usr/lib/gcc/i486-linux-gnu/4.3.2/../../../../lib/crt1.o: In function `_start':
(.text+0x18): undefined reference to `main'
collect2: ld returned 1 exit status

Notes:
1. The test framework's documentation says documentation may not be current:
file:///usr/share/doc/libboost-doc/HTML/libs/test/doc/index.html#ReleaseNotes
notes "I may not be able to make all necessary changes in
documentation within bounds of this release.".  This was my best guess
about what was required.  I have been able to use the framework in
earlier releases.  The release notes do note substantial changes in
the unit tests, including automatic ones.

2. I have had earlier versions on the system; some are still there:

3. I am using gcc 4.3, which I think is the Lenny default.  There does
not seem to be a gcc43 version above.  Perhaps that is the problem?
(But it's hard to believe it would be unable to find the symbol for
main).

4. 
nm -C /usr/lib/libboost_unit_test_framework.a | grep main
finds an entry for main, but when done against the .so produces only a
"no symbols" warning.  I don't know if it should do better.

5. I have pentium-builder installed, which puts a wrapper around g++.
Invoking g++-4.3 directly leads to the same results as above.
