无法在 OS X 上编译 GStreamer-Sharp

Question

我正试图在Mac上使用Gst#（这是GStreamer的C#绑定），但自动工具在最后几行一直失败：

checking whether to build shared libraries... yes
checking whether to build static libraries... yes
checking for pkg-config... /opt/local/bin/pkg-config
checking pkg-config is at least version 0.9.0... dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib
  Referenced from: /opt/local/bin/pkg-config
  Reason: Incompatible library version: pkg-config requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0
./configure: line 11558: 15968 Trace/BPT trap: 5       $PKG_CONFIG --atleast-pkgconfig-version $_pkg_min_version
no
checking for MONO_DEPENDENCY... no
checking for csc.exe... no
configure: error: You need to install either mono or .Net

说Mono没有安装是无稽之谈；我怎样才能解决这个问题并取得成功？如果有帮助的话，我通过Mac安装程序安装了Mono，而不是Macports，尽管Macports是安装的。

Answer 1

您的mono安装不在$PKG_CONFIG_PATH中，这就是为什么pkg config找不到mono的.pc文件。

您需要将目录添加到$PKG_CONFIG_PATH环境变量中。目录应位于/Library/Frameworks/Mono.framework/Versions/VERSIONNUMBER/lib/pkgconfig/

Answer 2

错误解释得很清楚：

Reason: Incompatible library version: pkg-config requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0

为了更新到新版本，我建议在Terminal:中尝试

sudo port -n upgrade --force libiconv
