android - 使用 DevIL 时出现错误“IL_LIB_JPEG_ERROR 1506”

Question

我正在编写一个使用DevIL进行图像处理的 Android 应用程序。我从这个项目中得到了 DevIL 的端口和它的依赖库。我编辑并提取了我需要的东西。它编译得很好，并且库可以工作，但是当我尝试加载JPEG文件时它不会...

使用 DevIL 错误代码，我发现错误号是 1506，它转换为IL_LIB_JPEG_ERROR，这意味着我的 JPEG 库中存在问题。我尝试更新到最新的 JPEG 库，但都失败了。我也尝试了其他 JPEG 文件，但没有任何成功。

这是android.mk显示 JPEG 和 DevIL 模块片段的文件：

您指定-DFT2_BUILD_LIBRARY=1何时构建DevIL库本身。这是对的。

但是，当您构建自己的与 DevIL 链接的应用程序时，您需要-DFT2_BUILD_LIBRARY=1再次指定该标志。这意味着 DevIL 标头将被误导，认为它们是为库本身而不是为第三方应用程序构建的。
