错误：FFmpeg ./configure 期间未找到 openssl

我正在尝试在 Ubuntu 上构建我的 FFmpeg 库，它具有以下依赖项：

  • libogg（/home/reccsi/Dev/build-x64/libogg）
  • libvorbis（/home/reccsi/Dev/build-x64/libvorbis）
  • libvpx（/home/reccsi/Dev/build-x64/libvpx）
  • libopenssl（/home/reccsi/Dev/build-x64/libopenssl）

我已经成功构建了它们，并将 pkg-config 文件添加到 /usr/share/pkgconfig 中

但是，当我配置 FFmpeg 时，我得到了这个：

$ ./configure  --prefix=/home/reccsi/Dev/build-x64/ffmpeg/  --pkg-config-flags="--static" --enable-shared --enable-libvpx --enable-libvorbis --enable-openssl --enable-pic --enable-debug
ERROR: openssl not found

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.
$

我认为这很奇怪，所以我查看了 config.log 并发现了这一点：

还有谁经历过这种情况吗？

答案1

$ git clone https://github.com/FFmpeg/FFmpeg.git
$ cd FFmpeg

$ ./configure --help | egrep -i '(ssl|tls)'
                           if openssl, librtmp or gmp is not used [no]
                           if openssl or librtmp is not used [no]
  --enable-gnutls          enable gnutls, needed for https support
                           if openssl is not used [no]
  --enable-openssl         enable openssl, needed for https support
                           if gnutls is not used [no]
  --disable-schannel       disable SChannel SSP, needed for TLS support on
                           Windows if openssl and gnutls are not used [autodetect]
  --disable-securetransport disable Secure Transport, needed for TLS support
                           on OSX if openssl and gnutls are not used [autodetect]

因此看起来您使用 启用了--enable-openssl，但是您以老式的方式添加了标题和库：

$ export CFLAGS="-I/usr/local/ssl/include -L/usr/local/ssl/lib -Wl,-rpath=/usr/local/ssl/lib"
$ CFLAGS="$CFLAGS" CXXFLAGS="$CFLAGS" ./configure --enable-openssl
...

configure应完整openssl列出外部库：

install prefix            /usr/local
source path               .
C compiler                gcc
C library                 
ARCH                      x86 (generic)
big-endian                no
runtime cpu detection     yes
nasm                      yes
...
SSE enabled               yes
SSSE3 enabled             yes
AESNI enabled             yes
AVX enabled               yes
XOP enabled               yes
...
makeinfo enabled          yes
makeinfo supports HTML    no

Enabled programs:
ffmpeg             ffprobe            ffserver

External libraries:
bzlib              libxcb_shape           openssl
iconv              libxcb_shm             videotoolbox
libxcb             libxcb_xfixes          zlib
...

如果你检查config.log，你会看到类似以下内容：

check_func_headers openssl/ssl.h SSL_library_init -I/opt/local/include -L/opt/local/lib -lssl -lcrypto
check_ld cc -I/opt/local/include -L/opt/local/lib -lssl -lcrypto

    2   long check_SSL_library_init(void) { return (long) SSL_library_init; }
    3   int main(void) { return 0; }

告诉SSL_library_init我 FFmpeg 只能与 OpenSSL 1.0.2 及以下版本一起使用。其他测试应适用于 OpenSSL 1.1.0 及以上版本。另请参阅编译和安装 | Autoconf在 OpenSSL wiki 上。
