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

在mac 10.6 snow leopard上编译时，libsndfile与libvorbis和libogg的链接错误,libsndfile,Libsndfile,大家好，我正在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，我已经确认它们是 x86_64库。我希望输出中有一个我不理解的提示 实施，有人能很快发现。谢谢你的关注 BREW错误输出： ==> Dow

大家好，我正在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，我已经确认它们是 x86_64库。我希望输出中有一个我不理解的提示 实施，有人能很快发现。谢谢你的关注

一个解决方案： 我遇到了类似但不完全相同的libsndfile链接器错误

问题似乎存在于libsndfile tar.gz本身提供的
配置
脚本中

这是个好消息。这意味着libvorbis二进制和libogg二进制都没有问题。不存在阻止libsndfile与自制的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\u CFLAGS=“$FLAC\u CFLAGS$OGG\u CFLAGS$VORBISENC\u CFLAGS”
外部自由库=“$FLAC自由库$VORBISENC自由库”


（这些行是逐字复制的。缩进在原始脚本中是不可靠的。）

你注意到不一致吗


EXTERNAL\u CFLAGS
是通过连接3组标志形成的，但是
EXTERNAL\u LIBS
是通过仅连接2组标志形成的

如下更新这些行可以让我构建和链接所有内容：


EXTERNAL\u CFLAGS=“$FLAC\u CFLAGS$OGG\u CFLAGS$VORBIS\u CFLAGS$vorbisence\u CFLAGS”
外部自由库=“$FLAC自由库$OGG自由库$VORBIS自由库$VORBISENC自由库”


这就是解决问题所需要的全部



我的背景故事：
在最初的帖子（作者@ubob）中，尝试2被描述为：“使用./configure和make手动安装libsndfile”

在不知道传递给
/configure
的选项（如果有）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源分发版本：libsndfile-1.0.24
（但我也尝试了libsndfile-1.0.25，发现与
外部库
的情况相同）

从自制中获得的依赖项：


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


我的生成命令：

导出CC=“铿锵-v”
export FLAC_CFLAGS=“-I/whicher/path/leads/to/FLAC/1.3.1/include”
export flaclibs=“-L/whicher/path/leads/toflac/1.3.1/lib-lFLAC.8”
export OGG_CFLAGS=“-I/whicher/path/leads/tolibogg/1.3.2/include”
export OGG_LIBS=“-L/whicher/path/leads/tolibogg/1.3.2/lib-logg.0”
export VORBIS_CFLAGS=“-I/whicher/path/leads/tolibvorbis/1.3.5/include”
export VORBIS_LIBS=“-L/whicher/path/leads/tolibvorbis/1.3.5/lib-lvorbis.0”
export VORBISENC_CFLAGS=“-I/whicher/path/leads/tolibvorbis/1.3.5/include”
export VORBISENC_LIBS=“-L/whicher/path/leads/tolibvorbis/1.3.5/lib-lvorbisenc.2-lvorbisfile.3”
./configure--enable external libs--disable static--enable shared--disable sqlite--disable dependency tracking
制作


一旦我对上述
EXTERNAL\u CFLAGS
和
EXTERNAL\u LIBS
进行了调整，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，并且运行良好
