错误：在ubuntu下编译简单的PjSIP程序

我想在ubuntu下编译简单的PjSIP程序。 我遇到了错误

/usr/bin/ld: cannot find -lpjsua-i686-pc-linux-gnu

这是什么意思？

这里是输出： -

root @ mypc-desktop：/ home / mypc / pjsip＃make

gcc -o myapp myapp.cpp -DPJ_AUTOCONF=1 -O2 -I/home/mypc/pjproject-1.4.5/pjlib/include -I/home/mypc/pjproject-1.4.5/pjlib-util/include -I/home/mypc/pjproject-1.4.5/pjnath/include -I/home/mypc/pjproject-1.4.5/pjmedia/include -I/home/mypc/pjproject-1.4.5/pjsip/include -L/home/mypc/pjproject-1.4.5/pjlib/lib -L/home/mypc/pjproject-1.4.5/pjlib-util/lib -L/home/mypc/pjproject-1.4.5/pjnath/lib -L/home/mypc/pjproject-1.4.5/pjmedia/lib -L/home/mypc/pjproject-1.4.5/pjsip/lib -L/home/mypc/pjproject-1.4.5/third_party/lib -lpjsua-i686-pc-linux-gnu -lpjsip-ua-i686-pc-linux-gnu -lpjsip-simple-i686-pc-linux-gnu -lpjsip-i686-pc-linux-gnu -lpjmedia-codec-i686-pc-linux-gnu -lpjmedia-i686-pc-linux-gnu -lpjmedia-audiodev-i686-pc-linux-gnu -lpjnath-i686-pc-linux-gnu -lpjlib-util-i686-pc-linux-gnu -lresample-i686-pc-linux-gnu -lmilenage-i686-pc-linux-gnu -lsrtp-i686-pc-linux-gnu -lgsmcodec-i686-pc-linux-gnu -lspeex-i686-pc-linux-gnu -lilbccodec-i686-pc-linux-gnu -lg7221codec-i686-pc-linux-gnu -lportaudio-i686-pc-linux-gnu -lpj-i686-pc-linux-gnu -lm -lnsl -lrt -lpthread

/usr/bin/ld: cannot find -lpjsua-i686-pc-linux-gnu collect2: ld returned 1 exit status make: *** [myapp] Error 1

这是代码

#include <pjlib.h>
#include <pjlib-util.h>
#include <pjmedia.h>
#include <pjmedia-codec.h>
#include <pjsip.h>
#include <pjsip_simple.h>
#include <pjsip_ua.h>
#include <pjsua-lib/pjsua.h>

int main()
{
        return 0;
}

这是一个Makefile

#Modify this to point to the PJSIP location.
PJBASE=/home/mypc/pjproject-1.4.5

include $(PJBASE)/build.mak

CC      = $(APP_CC)
LDFLAGS = $(APP_LDFLAGS)
LDLIBS  = $(APP_LDLIBS)
CFLAGS  = $(APP_CFLAGS)
CPPFLAGS= ${CFLAGS}

# If your application is in a file named myapp.cpp or myapp.c
# this is the line you will need to build the binary.
all: myapp

myapp: myapp.cpp
        $(CC) -o $@ $< $(CPPFLAGS) $(LDFLAGS) $(LDLIBS)

clean:
        rm -f myapp.o myapp

谢谢

编辑：

我只注意到建立PjSIP时出错

当我试图找到-werror make文件出现在/home/mypc/pjproject-1.4.5/pjnath/build ， $(PJDIR)/build.mak和$(PJDIR)/build/common.mak它不存在有人知道它可能在哪里？

---

似乎pj *不能构建必要的库文件 - 对于一个简单的修复尝试找到/home/mypc/pjproject-1.4.5/build.mak中的行，其中-Werror添加到$(APP_CFLAGS)并删除它（ - -Werror ，而不是整个行，如果其他标志被添加:)。

或者，在src/pjnath/stun_session.c 230行中应用gcc建议的修复。

编辑：
刚刚阅读，你发现没有 - -Werror 。 你可以将stun_session.c的第230行或make-files粘贴到某处？
源代码行将是首选。
