【问题描述】：

我正在尝试从此链接https://github.com/simena86/handDetectionCV 运行手势识别 openCV 示例项目。我在 cygwin 终端中运行 make 命令，但出现错误。我在 cygwin 终端 E:\handDetectionCVmaster\make

中运行以下命令

输出：

【问题讨论】：

我应该安装哪一个？

【参考方案1】：

这意味着您错过了 pkg-config 安装。这也是导致其余错误的原因，因为无法分别调用 pkg-config 命令的输出。

转到以下网址，获取并安装它：

http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/pkg-config_0.26-1_win32.zip

请注意，您可能需要从该站点安装更多依赖项，但基本上它应该可以工作。

【讨论】：

当我尝试从这个路径安装 E:\AR\openCV\pkg-config_0.26-1_win32\bin。我收到以下错误：程序无法启动，因为您的计算机缺少 libglib-2.0-0.dll

@user3496826：请参阅我的帖子中的Please note that you might need to install further dependencies from that site, but then it oughta work, basically.。 IOW，获取ftp.gnome.org/pub/gnome/binaries/win32/glib/2.28/… 和ftp.gnome.org/pub/gnome/binaries/win32/dependencies/…

我需要安装该链接中的所有依赖项吗？

@user3496826，是的，但为方便起见，请查看我评论中的两个链接。

如何从 gettext-runtime_0.18.1.1-2_win32\bin 安装 intl.dll
