c + +编译 - GSL在x86_64

我试图编译下面的代码：http://www-personal.umich.edu/~mejn/dcbm/KLOptimization.cpp c + +编译 - GSL在x86_64

但我从收到以下错误消息G ++：

> Undefined symbols for architecture x86_64: "_gsl_rng_uniform_int", 
> referenced from: 
>  Initialize()  in ccDEqovL.o 
>  _main in ccDEqovL.o "_gsl_rng_default_seed", referenced from:

什么对象是_gsl_rng_uniform_int？你是否将它与'ccDEqovL.o'链接？ – 2012-03-14 21:02:58

看起来你忘了链接GSL库。当你编译时，你的命令行是否包含'-lgsl'（我相信这是需要的）？ – 2012-03-14 21:04:07

...只是因为我有时会问这个问题 - 实际上是否已经手动将路径“/ usr/local/share/aclocal”添加到“/ usr/share/aclocal/dirlist”？ – 2012-03-14 21:07:19

看来你忘了GSL库链接：

我使用“酿造安装GSL”，这给了下面的输出装GSL。只需添加-lgsl，它应该工作（假设gsl在你的库路径中）。
