Macos 无法安装avconv/libav

我没有幸在OSX小牛上安装libav。我什么都试过了

我遵循以下指南：

在完成macport依赖项检查（通过）后，我运行

./configure \
--enable-gpl --enable-libx264 --enable-libxvid \
--enable-version3 --enable-libopencore-amrnb --enable-libopencore-amrwb \
--enable-nonfree --enable-libfaac \
--enable-libmp3lame --enable-libspeex --enable-libvorbis --enable-libtheora --enable-libvpx \
--enable-libopenjpeg --enable-libfreetype --enable-doc --enable-gnutls --enable-shared

此操作失败，出现以下错误：

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
ERROR: gnutls 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
libav-tools@libav.org mailing list or IRC #libav on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

错误：未找到gnutls

在运行configure之前，我已经在环境中添加了头文件的路径，但仍然没有成功

export CFLAGS="-I/opt/local/include -L/opt/local/lib"
export CXXFLAGS="-I/opt/local/include -L/opt/local/lib"

有人能帮忙吗

我和你犯了同样的错误。您需要安装gnutls

我在这里找到了一个指南：

此完整的命令列表适用于我（OSX 10.6）：

您还可以尝试使用Brew（）并通过以下方式安装gnutls：

 brew install gnutls

最后，第三种方法对我有效：

curl -O http://libav.org/releases/libav-10.1.tar.gz
tar xjf libav-10.1.tar.gz
cd libav-10.1
./configure
make install

享受吧

是否“brew安装libav”不足以满足您的需要？

重新安装后，它对我很有效：

使用以下命令从Mac上删除brew:

$ruby-e“$（curl-fsSLhttps://raw.githubusercontent.com/Homebrew/install/master/uninstall)“

---

使用：

$/usr/bin/ruby-e“$（curl-fsSL）再次安装它https://raw.githubusercontent.com/Homebrew/install/master/install)“

这给了我一个错误

错误：没有libav可用的公式。我mac osx 10.8.5上的m也为我工作
curl -O http://libav.org/releases/libav-10.1.tar.gz
tar xjf libav-10.1.tar.gz
cd libav-10.1
./configure
make install
