EXIF orientation will be an opt-in starting with Qt 5.5. +- On x86 and x86-64 systems with ELF binaries (especially Linux), due to + a new optimization in GCC 5.x in combination with a recent version of + GNU binutils, compiling Qt applications with -fPIE is no longer + enough. Applications now need to be compiled with the -fPIC option if + Qt's option "reduce relocations" is active. Note that Clang is known + to generate incompatible code even with -fPIC if the -flto option is + active. **************************************************************************** * Library * |
