Question

我从OpenCV网站下载了OpenCV 2.3.1并将其解压缩到/usr/share/src。我在该文件夹中运行sudo cmake .以生成make文件，然后运行“sudo make”我收到以下错误：

make [2]： *   [modules / highgui / CMakeFiles / opencv_highgui.dir / src / loadsave.o]错误1

make [1]： * [modules / highgui / CMakeFiles / opencv_highgui.dir / all]错误

这是为什么？我该如何解决？感谢

完整错误如下：

Answer 1

尝试the Wiki第2部分中使用CMake构建下的说明：

mkdir build
cd build
cmake -G "Unix Makefiles" ..
make -j8
sudo make install

Answer 2

您可能与之前安装的MacPorts存在冲突。运行：

port installed opencv

如果找到另一个版本的opencv，请使用：

sudo port deactivate opencv

然后再次运行make。

注意：它会根据您以前的opencv端口安装制动任何东西。因此，您需要再次激活旧版或调整依赖项以使用2.3.1。
