我是使用 iPhone 构建 pjsip 的新手。我正在使用 iOS 9.3.2、Xcode 7.3 和 Pjsip 2.5。我已经成功构建了没有 g729 的 Pjsip 2.5，并且没有 g729 也可以正常工作。由于我的应用程序也需要 g729，因此我遵循此处的所有说明

使用上述步骤启用 g729 后，在 "make dep && make clean && make" 时，它会为我用于我的应用程序的所有架构提供以下错误。

我真的被困在这里了。请帮我解决这个问题。任何人的一条线索都会有所帮助。

如果您按照您提到的链接进行操作，您需要做的修改很少。

  1. pjmedia/build/Makefile：
export PJMEDIA_CODEC_OBJS += audio_codecs.o ffmpeg_vid_codecs.o openh264.o\

                        h263_packetizer.o h264_packetizer.o \

                        $(OS_OBJS) $(M_OBJS) $(CC_OBJS) $(HOST_OBJS) \

                        ipp_codecs.o silk.o opus.o $(CODEC_OBJS) \

                        g7221_sdp_match.o amr_sdp_match.o **g729.o**
  1. pjmedia/build/os-auto.mak.in：
 export CFLAGS += -I$(THIRD_PARTY)/g729/**Headers** 

-DPJMEDIA_HAS_G729_CODEC=1
  1. 如下更改生成文件 (third_party/build/g729/Makefile) ：

（注意：请确保您遵循makefile的规则，如果在任何情况下出现任何错误。要确认，请先使用make命令构建third_party/build/g729/Makefile。看看它是否成功，那么完整的构建也将成功.)
