Question

我正在尝试使用Iup和OpenCV运行基本应用程序。该应用程序的主要目标是显示图像并允许用户以各种有趣的方式进行分析，但这是现在无关紧要的。我需要知道的是以下错误消息的含义，以及如何修复它们。我的应用程序仍然可以运行得很好，并显示图像进行分析，但每次重新绘制窗口时这些错误似乎都会被重新打印：

Answer 1

它看起来像你正在使用的GTK +主题中的一个错误（Mint-X）。图像被破坏或者不符合滚动条的预期。与您的代码无关。

如果您尝试使用其他主题（假设新主题未被破坏），则不应该看到该错误。此外，您应该将错误报告给Linux Mint。您还可以检查是否有最新版本（请参阅http://packages.linuxmint.com/pool/main/m/mint-x-theme/）。

另外，如果你足够勇敢，你可以尝试使用git存储库自己修复它：https://github.com/linuxmint/mint-x-theme

Answer 2

如果您在运行时使用动态模块编译了gdk-pixbuf，则会出现此错误，但是找不到所需的加载程序。如果您将gdk-pixbuf静态链接到您的应用程序但未发送加载程序文件，则会发生这种情况。

最佳解决方案是重新编译gdk-pixbuf并将所有加载器嵌入到库中：

./configure --disable-modules --with-included-loaders=yes

GdkPixbuf-CRITICAL **：gdk_pixbuf_get_width：断言`GDK_IS_PIXBUF（pixbuf）'失败
