[Bug-gsl] Dear Teacher, I have a problem with GSL, if you have free time, please help me!

[Fu Changhong]

Dear Teacher:
>         I am sorry to trouble you, but I eager to use the GSL in my research, 
>I had installed the gsl-1.15, and the command window also show that the 
>library has been installed successfully! But 
when I "make" my codes, some errors has been shown, the 
following content is the error, I want to use it with OpenCV together, I always 
use the OpenCV, so I think it 
is not the problem with the OpenCV, have you encounter the same error 
before, I think you could help me, thank you!!
