Cmake 错误未定义的符号x86_64
Cmake error undefined symbols for x86_64
我正在尝试使用xcode编译Mac osx yosemite中的conv-net库。我什至将标志设置为 libstdc++ 仍然无法正确链接。
我仍然得到建筑x86_64的未定义符号。任何帮助非常感谢。

我通过在编译器标志中添加 -c 选项来修复它,它!!!
add_executable
命令采用目标名称和要编译的源文件列表。当您为testimg
创建目标时,您正在传递它目录。
使用 file(GLOB ...( 命令将所有源文件从目录收集到一个列表变量中,并将其传递给add_executable
调用。
