I want to test an early version of my program on a different machine, so I switched the solution to Release. Trying to compile this, I get a bunch of linker errors that all end the same:

Code:
1>libboost_filesystem-vc100-mt-gd-1_44.lib(unique_path.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '2' doesn't match value '0' in BoostTesting.obj

After Googling it, I came up with a bunch of people saying that they'd had it happen, but no solutions. Does anyone know why this is happening?
