Re: [Help-gsl] delete function generates an error in movstat.h

[Patrick Alken]

Daniel,

  Sorry for the slow reponse. The problem is that "delete" is a C++ 
keyword which g++ doesn't like in that header file. I always use gcc to 
compile so I didn't see this problem. Please edit your gsl_movstat.h 
header file and change "delete" to "delete_sample". Then try compiling 
your code.

I will make this update in the git repository also.

Patrick
