pjsip ld中gcc的编译错误返回1退出状态

我试图用ZRTP4PJ编译pjsip，我发现了一个问题

在我需要添加pjsua_app.o之后，我将完成上面的编译，并将其添加到下一个命令：

gcc -o ../bin/pjsua-x86_64-unknown-linux-gnu      output/pjsua-x86_64-unknown-linux-gnu/main.o  output/pjsua-x86_64-unknown-linux-gnu/pjsua_app.o  output/pjsua-x86_64-unknown-linux-gnu/pjsua_app_cli.o  output/pjsua-x86_64-unknown-linux-gnu/pjsua_app_common.o  output/pjsua-x86_64-unknown-linux-gnu/pjsua_app_config.o  output/pjsua-x86_64-unknown-linux-gnu/pjsua_app_legacy.o -L/home/aa/ma/pjproject-2.4.5/pjlib/lib -L/home/aa/ma/pjproject-2.4.5/pjlib-util/lib -L/home/aa/ma/pjproject-2.4.5/pjnath/lib -L/home/aa/ma/pjproject-2.4.5/pjmedia/lib -L/home/aa/ma/pjproject-2.4.5/pjsip/lib -L/home/aa/ma/pjproject-2.4.5/third_party/lib  -lavcodec -lswscale -lavutil   -lv4l2    -lavcodec -lswscale -lavutil   -lv4l2    -lpjsua-x86_64-unknown-linux-gnu -lpjsip-ua-x86_64-unknown-linux-gnu -lpjsip-simple-x86_64-unknown-linux-gnu -lpjsip-x86_64-unknown-linux-gnu -lpjmedia-codec-x86_64-unknown-linux-gnu -lpjmedia-x86_64-unknown-linux-gnu -lpjmedia-videodev-x86_64-unknown-linux-gnu -lpjmedia-audiodev-x86_64-unknown-linux-gnu -lpjmedia-x86_64-unknown-linux-gnu -lpjnath-x86_64-unknown-linux-gnu -lpjlib-util-x86_64-unknown-linux-gnu  -lsrtp-x86_64-unknown-linux-gnu -lresample-x86_64-unknown-linux-gnu -lgsmcodec-x86_64-unknown-linux-gnu -lspeex-x86_64-unknown-linux-gnu -lilbccodec-x86_64-unknown-linux-gnu -lg7221codec-x86_64-unknown-linux-gnu -lportaudio-x86_64-unknown-linux-gnu  -lpj-x86_64-unknown-linux-gnu -lssl -lcrypto -lm -lrt -lpthread  -lasound  -lavcodec -lswscale -lavutil   -lv4l2

我得到以下错误：

collect2: error: ld returned 1 exit status

你知道怎么解决这个问题吗？

显然，我在第一个gcc中做了一些愚蠢的事情来编译这个：

gcc-o../bin/pjsua-x86_64-unknown-linux-gnu（…）

你忘了这两行：

-lzsrtp-x86_64-unknown-linux-gnu
-lstdc++

让我知道它是否有效，给我反馈

-lzsrtp-x86_64-unknown-linux-gnu
-lstdc++
