[英]c# GTK 2 & 3 conflict when using Emgucv
I found a strange confict when using Emgu with class 'ImageViewer' 当将Emgu与类'ImageViewer'一起使用时,我发现了一个奇怪的冲突
When I have no static class member, everything work just fine. 当我没有静态的类成员时,一切正常。 for example, code like below
例如下面的代码
using Emgu.CV;
using Emgu.CV.Util;
using Emgu.CV.UI;
namespace TmpTest
{
class TmpTest
{
private Mat img = new Mat(); // a non-static class member is OKey
public static void Main(string[] arg)
{
SDKWrapper util = new SDKWrapper();
ImageViewer viewer = new ImageViewer ();
VideoCapture capture = new VideoCapture ();
Application.Idle += new EventHandler (delegate(object sender, EventArgs e) {
Mat read_frame = capture.QueryFrame();
util.processFrame(read_frame);
util.drawSkeleton(read_frame);
viewer.Image = read_frame;
});
viewer.ShowDialog ();
return;
}
}
}
But as soon as I add a static class member, for example, change private Mat img
into private static Mat img
, I got an runtime error immediately like this 但是,一旦我添加了静态类成员,例如,将
private Mat img
更改为private static Mat img
,我就立即遇到运行时错误
Gtk-ERROR **: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported
I'm using ubuntu 16.04 and monodevelopment, does anyone knows what had happened and how to solve it? 我正在使用ubuntu 16.04和monodevelopment,有人知道发生了什么事以及如何解决它?
Emgu CV is a .Net wrapper to OpenCV. Emgu CV是OpenCV的.Net包装器。 Depending on the OpenCV version you use, it can be build against GTK 2 or GTK 3, but usually is against GTK 2. However, an application can't use GTK 2 and GTK 3 at the same time.
根据您使用的OpenCV版本,它可以针对GTK 2或GTK 3构建,但通常针对GTK2。但是,应用程序不能同时使用GTK 2和GTK 3。 So I think the OpenCv part uses GTK 2 and you have something else pulling GTK 3. You should check on which libraries the binaries of emgu CV you're using depend.
因此,我认为OpenCv部分使用GTK 2,而您还有其他方面可以使用GTK3。您应该检查所使用的emgu CV二进制文件依赖于哪些库。
