Question

我正在尝试在Mac上为Android构建VLC，但我收到了以下错误：

INSTALL libavformat/libavformat.a
{standard input}: Assembler messages:
{standard input}:146: Error: unknown register alias 'GP'
clang38: error: assembler command failed with exit code 1 (use -v to see invocation)
make[1]: *** [libavcodec/arm/ac3dsp_armv6.o] Error 1
make[1]: *** Waiting for unfinished jobs....
{standard input}: Assembler messages:
{standard input}:446: Error: unknown register alias 'POUT'
{standard input}:448: Error: unknown register alias 'PIN'
{standard input}:450: Error: unknown register alias 'PCOEF'

有人告诉我应该修改.configure以禁用asm。我该怎么办？那不会破坏VLC的性能吗？

Answer 1

如何禁用asm： 1. vi vlc / contrib / src / ffmpeg / rules.mak 2.添加选项“disable-asm”

FYI
