lapacke.h uses // comments preventing compilation with -ansi

[wryanlivingston]

Hi all,

If one looks in LAPACK/lapacke/include/lapacke.h there are a few C++ style comments using "//" rather than "/* */". When including lapacke.h in a build that uses a strict C mode (e.g. -ansi with gcc) this results in compilation errors. Would it be feasible to turn those into /* */ comments?

Thanks,
W. Ryan Livingston

Code: Select all

/* foo.c */
#include "lapacke.h"

% gcc -c foo.c -I/path/to/LAPACK/lapacke/include/ -ansi

Ryan,

You could alternatively use the -std=c99 option to conform to the ISO C99 standard, which added // as a valid comment prefix.
