// NB: This file contains macros for checking binary compatibility of libraries

// in multilib buildm, plugins and user components.
|
|
// The WX_BUILD_OPTIONS_SIGNATURE macro expands into string that should
|
|
// uniquely identify binary compatible builds: i.e. if two builds of the
|
|
// library are binary compatible, their signature string should be the
|
|
// same; if two builds are binary incompatible, their signatures should
|
|
// be different.
|
|
//
|
|
// Therefore, wxUSE_XXX flags that affect binary compatibility (vtables,
|
|
// function signatures) should be accounted for here. So should compilers
|
|
// and compiler versions (but note that binary compatible compiler versions
|
|
// such as gcc-2.95.2 and gcc-2.95.3 should have same signature!).
