c++ - 使用libsrtp编译 Asterisk 时出错

我想用SRTP库编译星号，但是在配置星号代码时，出现此错误:

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: *** with ./configure CFLAGS=-fPIC --prefix=/usr
configure: WARNING: *** replacing /usr with the prefix of your choice.
configure: WARNING: *** After re-installing libsrtp
configure: WARNING: *** configure script.
configure: WARNING: ***
configure: WARNING: *** If you do not need SRTP support re-run configure
configure: WARNING: *** with the --without-srtp option.

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"
    AC_MSG_CHECKING(for the ability of -lsrtp to be linked in a shared object)
    AC_LINK_IFELSE(
    [
        AC_LANG_PROGRAM(
            [#include <srtp/srtp.h>],
            [srtp_init();]
        )
    ],

    [ AC_MSG_RESULT(yes) ],
    [
        AC_MSG_RESULT(no)
        AC_MSG_NOTICE(***)
        AC_MSG_NOTICE(*** libsrtp could not be linked as a shared object)
        AC_MSG_NOTICE(*** try compiling libsrtp manually and configuring with)
        AC_MSG_NOTICE(*** ./configure CFLAGS=-fPIC --prefix=/usr)
        AC_MSG_NOTICE(*** replacing /usr with the prefix of your choice)
        exit 1
    ]
    )
    LIBS="${saved_libs}"
    LDFLAGS="${saved_ldflags}"
fi

我尝试使用多个前缀来编译libsrtp代码，但得到的结果相同。
有什么建议吗？

最佳答案

警告说它不能与libsrtp链接，因为libsrtp的代码需要可重定位，就像共享库一样，而且看来您正在将libsrtp编译为静态库，我会按照建议执行并重新构建 libsrtp 使用:

./configure CFLAGS=-fPIC

我在这里也尝试过，并且有效，请注意，在构建libsrtp时我使用了默认前缀/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
