Sorry to say the libavcodec/faandct.c patch prevents compilation on a ppc using GCC 5.2.0. In all cases (the first of which are given below), the GCC "note" states: "in expansion of macro 'Bn'" ...where n is the digit following B libavcodec/faandct.c:39:12: error: initializer element is not constant #define B1 0.720959822006947913789091890943021267L // (cos(pi*1/16)sqrt(2))^-1 ... libavcodec/faandct.c:40:12: error: initializer element is not constant #define B2 0.765366864730179543456919968060797734L // (cos(pi*2/16)sqrt(2))^-1 ... libavcodec/faandct.c:41:12: error: initializer element is not constant #define B3 0.850430094767256448766702844371412325L // (cos(pi*3/16)sqrt(2))^-1 ... libavcodec/faandct.c:43:12: error: initializer element is not constant #define B5 1.272758580572833938461007018281767032L // (cos(pi*5/16)sqrt(2))^-1 ... libavcodec/faandct.c:44:12: error: initializer element is not constant #define B6 1.847759065022573512256366378793576574L // (cos(pi*6/16)sqrt(2))^-1 ... libavcodec/faandct.c:45:12: error: initializer element is not constant #define B7 3.624509785411551372409941227504289587L // (cos(pi*7/16)sqrt(2))^-1 ... kind regards, John _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
