Re: FTBFS on GNU/Hurd

[Matthew Lien]

Hi Ludovic,

Sure I would like to test for you, but don't see any code to change. In your mail between the line
"Could you try changing lines 174 and 177 like this:"

and
"This is not a problem on GNU/Linux where argp.h does this:"

is an empty space.

What file and what content should I edit?

Best wishes,

BlueT

Could you try changing lines 174 and 177 like this:



This is not a problem on GNU/Linux where argp.h does this:

  #ifndef __error_t_defined
  typedef int error_t;
  # define __error_t_defined
  #endif

... whereas on GNU/Hurd ‘error_t’ is a enum, and is always defined:

  typedef enum __error_t_codes error_t;

TIA,
Ludo’.
