17 | // NB: This file contains macros for checking binary compatibility of libraries | |
18 | // in multilib buildm, plugins and user components. | |
19 | // The WX_BUILD_OPTIONS_SIGNATURE macro expands into string that should | |
20 | // uniquely identify binary compatible builds: i.e. if two builds of the | |
21 | // library are binary compatible, their signature string should be the | |
22 | // same; if two builds are binary incompatible, their signatures should | |
23 | // be different. | |
24 | // | |
25 | // Therefore, wxUSE_XXX flags that affect binary compatibility (vtables, | |
26 | // function signatures) should be accounted for here. So should compilers | |
27 | // and compiler versions (but note that binary compatible compiler versions | |
28 | // such as gcc-2.95.2 and gcc-2.95.3 should have same signature!). | |
