However, if your project already uses TR1 tuple, you need to +tell Google Test to use the same TR1 tuple library the rest of your +project uses (this requirement is new in Google Test 1.4.0, so you may +need to take care of it when upgrading from an earlier version), or +the two tuple implementations will clash. To do that, add + + -DGTEST_USE_OWN_TR1_TUPLE=0 + +to the compiler flags while compiling Google Test and your tests. + +If you don't want Google Test to use tuple at all, add + + -DGTEST_HAS_TR1_TUPLE=0 + +to the compiler flags. All features using tuple will be disabled in +this mode. + Building the Source ------------------- ### Linux, Mac OS X (without Xcode), and Cygwin ### |
