Question

我是iPhone的pjsip构建的新手。我使用的是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它工作正常。由于我的应用程序也需要g729，我遵循here

的所有指令

使用上述步骤启用g729后，在“make dep＆amp;＆amp; make clean＆amp;＆amp; make”中，它为我的应用程序使用的所有架构提供了以下错误。

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。

如果您正在关注您提到的链接，则无需进行任何修改。

pjmedia / build / Makefile：

<?php
require_once 'dompdf/autoload.inc.php';
?>
<?php

// reference the Dompdf namespace

use Dompdf\Dompdf;

// instantiate and use the dompdf class
$dompdf = new Dompdf();
$dompdf->load_html_file('https://www.lotomanager.in/en/print-job.php?ID='.(int)$_GET['ID']);

// (Optional) Setup the paper size and orientation
$dompdf->setPaper('A4', 'landscape');

// Render the HTML as PDF
$dompdf->render();

// Output the generated PDF to Browser
$dompdf->stream();
?>

pjmedia / build / os-auto.mak.in：

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**

如下所示更改makefile（third_party / build / g729 / Makefile）：

（注意：请确保您遵循makefile的规则，如果在任何情况下它都会出现任何错误。要确认，首先构建third_party / build / g729 / makefile使用make命令。看看它是否成功，然后完整的构建也将成功。）

 export CFLAGS += -I$(THIRD_PARTY)/g729/**Headers** 

-DPJMEDIA_HAS_G729_CODEC=1

适用于iPhone的PJSIP2.5支持G729编解码器
