Hi!
I just learnt about what looks like an ABI regression in Qt 5.2:
The function QFontDatabase::supportsThreadedFontRendering() got deprecated
in 5.2 with commit b0b786a2f05e9451a65519ab8904f55c35f51b7d:
- static bool supportsThreadedFontRendering();
+#if QT_DEPRECATED_SINCE(5, 2)
+ QT_DEPRECATED static inline bool supportsThreadedFontRendering() {
return true; }
+#endif
At the same time it got inlined. At least with MinGW this made the symbol
go away. While e.g. MSVC still exports it.
Now I don't know the exact strategy pursured by QT_DEPRECATED but I assume
that the function's symbol should not disappear from the 5.2 ABI? If so,
I wonder whether removing the "inline" will already do the job.
Harri.
