在 mac 10.6 雪豹上编译时，libsndfile 与 libvorbis 和 libogg 的链接错误

Question

您好，我正在尝试在 Mac OSX 10.6 上编译 libsndfile 1.0.25

我已经用 brew 安装了 libvorbis-1.3.4 和 libogg-1.3.1

1 - 我尝试使用 brew 安装 libsndfile

2 - 我尝试使用 ./configure 和 make 手动安装 libsndfile

./configure 步骤似乎确实找到了 libvorbis 和 libogg，我已经确认这些是 x86_64 库。我希望输出中有一个我不明白的提示 实施并且有人可以快速发现它。感谢收看！

冲泡错误输出：

Answer 1

一个解决方案：

我遇到了类似但不相同的 libsndfile 链接器错误。

问题似乎出在 libsndfile tar.gz 本身提供的configure 脚本中。

这是个好消息。这意味着 libvorbis 二进制文件和 libogg 二进制文件都没有问题。不存在阻止 libsndfile 与 homebrew 提供的 libvorbis 和 libogg 链接的基本 ABI 问题。

我在 libsndfile 的 configure 脚本中找到了这些行：

    EXTERNAL_CFLAGS="$FLAC_CFLAGS $OGG_CFLAGS $VORBISENC_CFLAGS"
        EXTERNAL_LIBS="$FLAC_LIBS $VORBISENC_LIBS"

（这些行是逐字复制的。原始脚本中的缩进很奇怪。）

你注意到不一致了吗？

EXTERNAL_CFLAGS 是通过连接 3 组标志形成的，但 EXTERNAL_LIBS 是通过仅连接 2 组形成的。

如下更新这些行使我能够构建和链接所有内容：

    EXTERNAL_CFLAGS="$FLAC_CFLAGS $OGG_CFLAGS $VORBIS_CFLAGS $VORBISENC_CFLAGS"
        EXTERNAL_LIBS="$FLAC_LIBS $OGG_LIBS $VORBIS_LIBS $VORBISENC_LIBS"

这就是解决问题所需要的全部内容。

我的背景故事：

在原帖（@ubob）中，尝试 2 被描述为：“使用 ./configure 和 make 手动安装 libsndfile”

在不知道将哪些选项（如果有）传递给./configure 的情况下，我无法确定我的答案是否适用于@ubob 的场景。

我的操作系统：Mac OS X 10.8.1

libsndfile 源码分发版本：libsndfile-1.0.24 （但我也试过 libsndfile-1.0.25 发现和EXTERNAL_LIBS一样的情况）

从自制软件获得的依赖： flac/1.3.1/lib/libFLAC.8.dylib libogg/1.3.2/lib/libogg.0.dylib libvorbis/1.3.5/lib/libvorbis.0.dylib libvorbis/1.3.5/lib/libvorbisenc.2.dylib libvorbis/1.3.5/lib/libvorbisfile.3.dylib

我的构建命令：

export CC="clang -v"
export FLAC_CFLAGS="-I/whichever/path/leads/to/flac/1.3.1/include"
export FLAC_LIBS="-L/whichever/path/leads/toflac/1.3.1/lib -lFLAC.8"
export OGG_CFLAGS="-I/whichever/path/leads/tolibogg/1.3.2/include"
export OGG_LIBS="-L/whichever/path/leads/tolibogg/1.3.2/lib -logg.0"
export VORBIS_CFLAGS="-I/whichever/path/leads/tolibvorbis/1.3.5/include"
export VORBIS_LIBS="-L/whichever/path/leads/tolibvorbis/1.3.5/lib -lvorbis.0"
export VORBISENC_CFLAGS="-I/whichever/path/leads/tolibvorbis/1.3.5/include"
export VORBISENC_LIBS="-L/whichever/path/leads/tolibvorbis/1.3.5/lib -lvorbisenc.2 -lvorbisfile.3"

./configure --enable-external-libs --disable-static --enable-shared  --disable-sqlite --disable-dependency-tracking

make

一旦我对EXTERNAL_CFLAGS 和EXTERNAL_LIBS 进行了如上所述的调整，我就能够成功地构建一个合适的libsndfile.1.dylib，它现在在我的应用程序中得到了很好的使用并且工作正常。
