Compiling/linking in MS Visual Studio Express 2013

[James Henry <tigerstripe40@…>]

Trying to run boost testing for Exercism Bob C++ exercise. I cannot run the test.

Getting: Error 1 error LNK2005: "bool cdecl init_unit_test(void)" (?init_unit_test@@YA_NXZ) already defined in bob.obj C:\Users\bubba\exercism\cpp\bob\Bob\bob_test.obj Bob Error 2 error LNK2005: _main already defined in bob.obj C:\Users\bubba\exercism\cpp\bob\Bob\bob_test.obj Bob Error 3 error LNK1104: cannot open file 'boost_unit_test_framework-vc120-mt-gd-1_56.lib' C:\Users\bubba\exercism\cpp\bob\Bob\LINK Bob

Error 3 indicates cannot open file: 'boost_unit_test_framework-vc120-mt-gd-1_56.lib' However, I have 'libboost_unit_test_framework-vc120-mt-gd-1_56.lib' in the path.

renaming the file results in the following errors:

You need to link against a compatible library variant - and as you've discovered the library you renamed is not that. Suggest you delete all your libboost_unit_test*.* files then rebuild Boost using the --build-type=complete option. See also http://www.boost.org/doc/libs/1_56_0/more/getting_started/windows.html
