碰到的编译错误如下：

lame/libmp3lame/vector/xmm_quantize_sub.c:72:18: warning: SSE vector return without SSE enabled changes the ABI [-Wpsabi]72 |     const __m128 vec_fabs_mask = _mm_loadu_ps(&fabs_mask._float[0]);|                  ^~~~~~~~~~~~~

这个从config.h来看，configure阶段会检测到支持SSE指令，所以HAVE_XMMINTRIN_H为1，在wrapper的Makefile中通过-DHAVE_XMMINTRIN_H=0是不行的。

搜索发现之前有人碰到过，我这里这个问题添加编译选项即可：

-msse

这个通过后面的网址搜索“_mm_set_ps1 ”函数，通过查找对应的SSE指令集即可：网址，对应的CPUID Flags: SSE，所以参数cflags参数是msse:

__m128 _mm_set_ps1 (float a)Synopsis
__m128 _mm_set_ps1 (float a)
#include <xmmintrin.h>
Instruction: Sequence
CPUID Flags: SSE
Description
Broadcast single-precision (32-bit) floating-point value a to all elements of dst.
Operation
FOR j := 0 to 3i := j*32dst[i+31:i] := a[31:0]
ENDFOR

编译libmp3lame.a的cflags：

CFLAGS += -DHAVE_CONFIG_H
CFLAGS += $(INCDIR_PREFIX)$(DST_PATH) \$(INCDIR_PREFIX)$(SRC_PATH)/include \$(INCDIR_PREFIX)$(SRC_PATH)/mpglib \$(INCDIR_PREFIX)$(SRC_PATH)/libmp3lame
CFLAGS += -Wno-unused-variable -Wno-unused-but-set-variable \-Wno-stringop-overflow -Wno-array-parameter \-Wno-address -Wno-shadow -msse
