【问题描述】:
我正在尝试在 mac 上构建 rtmpdump 和 librtmp,但是我终其一生都无法弄清楚它为什么不起作用。我正在使用自己构建的 openssl:
$ openssl version
OpenSSL 1.1.0-pre3 (alpha) 15 Feb 2016
我已经正确设置了标志(我认为),但是当我尝试编译时,我得到了这个:
$ make INC=-I/usr/local/include
gcc -Wall -I/usr/local/include -DRTMPDUMP_VERSION=\"v2.4\" -DUSE_OPENSSL -O2 -fPIC -c -o rtmp.o rtmp.c
In file included from rtmp.c:152:

看起来这可能是我使用的 OpenSSL 版本的兼容性问题。有谁知道如何解决此类问题,或者对 OpenSSL 进行任何可能负责的更改?
