我已经使用通过macports安装的opencv编译代码。但是，在运行我的makefile时，我得到了
ld: warning: in /opt/local/lib/libopencv_core.dylib, file was built for unsupported file format which is not the architecture being linked (i386)

这是否意味着图书馆都没有链接？我该怎么办？
答案 0 :(得分：0)
问题是您正在编译一个架构的代码（可能是x86_64，即Intel 64位），并且您要求使用i386架构构建macport，即32位
所以你需要改变其中一个。
1）更改代码 - 在编译规则中将-arch x86_64添加到gcc的选项中。
2）卸载macports然后重新安装并在macports.conf文件中选择所需的build_arch，并检查应该默认为两者的universal_archs。
