g ++ ld：对于架构x86_64找不到符号 [英] g++ ld: symbol(s) not found for architecture x86_64

问题描述

我正在尝试编译Sam Hare的 Struck代码。

I'm trying to compile the Sam Hare's Struck code.

我使用mac OSX10.9，opencv 2.4.6和Eigen 2.0.17。

I'm using mac OSX10.9, opencv 2.4.6 and Eigen 2.0.17.

Eigen和opencv头文件存储在/ opt / local / include，而opencv dylib在/ opt / local / lib中。

Eigen and opencv headers are stored in /opt/local/include while opencv dylib in /opt/local/lib.

我修改了Hare的Makefile，当我在终端上键入make：

I modified the Hare's Makefile to work on this folder. When I type make on the terminal:

g++ -L/opt/local/lib -lopencv_core -lopencv_highgui -lopencv_imgproc src/Config.o src/Features.o src/HaarFeature.o src/HaarFeatures.o src/HistogramFeatures.o src/ImageRep.o src/LaRank.o src/MultiFeatures.o src/RawFeatures.o src/Sampler.o src/Tracker.o src/main.o src/GraphUtils/GraphUtils.o -o struck

：

Undefined symbols for architecture x86_64:

      _main in main.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see

任何想法？谢谢！

推荐答案

终于解决了我的问题。

我在XCode中创建了一个新项目， libc ++至libstdc ++，如此和此。

I created a new project in XCode with the sources and changed the C++ Standard Library from the default libc++ to libstdc++ as in this and this.
