• How to avoid the "text relocation" error by ffmpeg library on Android x86

  16 octobre 2017, par Tank2005

  My environment is Qt 5.9 for Android on Windows 10 64bit. NDK is r10e and SDK Level is 16(Those sdks are recommended version by Qt development team).

  I built a ffmpeg 3.4 source code as .so files on Ubuntu 16.04.3 LTS. Those library has no error on ARM architecture Android. But, on x86 Emulator, "Text realocations" alart is shown like this.

  

  I rewrite configure with "disable-asm, disable-yasm" referd from this site’s old posts.

  This hereby removed some errors. But only one library has a problem.
  

  I also tried the method of deleting "strtod.o", But it seems no effect. My current build configure is that. Does anyone know a better way ?

• Revert "configure : Disable -Wbool-operation."

  9 octobre 2017, par Mark Thompson

  Revert "configure : Disable -Wbool-operation."
  This reverts commit c2d155e11ee5ec732d471982f2dee43703bcd5a7.
  GCC 6 incorrectly passes the configure test and then logs many warnings
  
  of the form :
  src/libavformat/dump.c : At top level :
  
  cc1 : warning : unrecognized command line option ‘-Wno-bool-operation’
