// -----------------------------

48 |

|
|
// Google Test can be used in many different environments. Macros in
|
50 |
|
|
// this section tell Google Test what kind of environment it is being
|
51 |
|
|
// used in, such that Google Test can provide environment-specific
|
52 |
|
|
// features and implementations.
|
53 |
|
|
//
|
54 |
|
|
// Google Test tries to automatically detect the properties of its
|
55 |
|
|
// environment, so users usually don't need to worry about these
|
56 |
|
|
// macros. However, the automatic detection is not perfect.
|
57 |
|
|
// Sometimes it's necessary for a user to define some of the following
|
58 |
|
|
// macros in the build script to override Google Test's decisions.
|
59 |
|
|
//
|
60 |
|
|
// If the user doesn't define a macro in the list, Google Test will
|
61 |
|
|
// provide a default definition. After this header is #included, all
|
62 |
|
|
// macros in this list will be defined to either 1 or 0.
|
63 |
|
|
//
|
64 |
|

// Notes to maintainers:

|
|
// - Each macro here is a user-tweakable knob; do not grow the list
|
66 |
|
|
// lightly.
|
67 |
|
|
// - Use #if to key off these macros. Don't use #ifdef or "#if
|
68 |

// defined(...)", which will not work as these macros are ALWAYS

|
|
