libvpx vp8 编码器：添加了所有依赖项但仍然 vp8_multi_resolution_encoder.file 编译错误

问题描述

我正在尝试编译文件。我已经构建了 libvpx 并使用 configure --target=x86_64-linux-gcc 进行制作。首先，我从示例文件夹中复制了 c 文件。然后开始编辑。首先解决所有包含问题。主要与 vpx_config.h 有关。都解决了仍然显示vpx_codec_control undefined。

我做错了什么吗？这里有解决方案Undefined references when compiling project with libvpx 与此问题有关，但没有帮助我。

如果我尝试用 g++ 而不是 gcc 编译

g++ vp8_multi_resolution_encoder.c
