我想用SRTP库编译星号，但在配置星号代码时，我收到此错误：
checking for the ability of -lsrtp to be linked in a shared object... no
configure: WARNING: ***
configure: WARNING: *** libsrtp could not be linked as a shared object.
configure: WARNING: *** Try compiling libsrtp manually. Configure libsrtp

configure: WARNING: *** After re-installing libsrtp

configure: WARNING: ***
configure: WARNING: *** If you do not need SRTP support re-run configure

这也是检查此规则的代码：
if test "$PBX_SRTP" = "1";
then
saved_libs="${LIBS}"
saved_ldflags="${LDFLAGS}"
LIBS="${LIBS} -lsrtp"
LDFLAGS="${LDFLAGS} -shared -fPIC"

我尝试了几个前缀来编译 libsrtp 代码，但我得到了相同的结果。有什么建议吗？
警告说它无法与 libsrtp 链接，因为 libsrtp 的代码需要可重定位，就像共享库一样，而且您似乎正在将 libsrtp 编译为静态库，我会按照它的建议进行操作并使用以下方法重新构建 libsrtp：
./configure CFLAGS=-fPIC
我也在这里尝试过并且它有效，请注意，我在构建 libsrtp 时使用了默认前缀/use/local/lib
./configure --with-srtp=/usr/local/lib
checking for srtp_init in -lsrtp... yes
checking srtp/srtp.h usability... yes
checking srtp/srtp.h presence... yes
checking for srtp/srtp.h... yes
checking for the ability of -lsrtp to be linked in a shared object... yes
SRTP 文件夹中的
：
make uninstall
make clean
./configure CFLAGS=-fPIC --prefix=/usr/local/lib
make
make runtest
make install
在星号文件夹中：
cd ../../asterisk/asterisk-11.3.0/
./configure --with-srtp=/usr/local/lib
这对我有用
构建脚本检查对srtp_init()的简单调用是可编译的，为了有效，您应该有一个文件夹，该文件夹在包含文件的路径中包含<srtp>，并在链接器的路径中创建.a库。因此，在创建libsrtp后，将前缀放在链接器路径中
