Comment (by guest):
In order to use my local GNUreadline framework I had to change
`libraries/readline/configure.ac` (attached) and
`libraries/readline/include/HsReadline.h`. The case distinction in the
latter file did not work because recursively included files like
`readline/rlstdc.h` did not have the `GNUreadline/` prefix.
(I wonder if (or why) this worked for a global `GNUreadline.framework` in
`/Libary/Frameworks/`.)
So I left `HsReadline.h` as:
{{{
#ifndef HSREADLINE_H
#define HSREADLINE_H
#include "HsReadlineConfig.h"
#include <stdio.h>
#include <readline/readline.h>
#include <readline/history.h>
extern void hs_rl_message (const char *s);
#endif
}}}
Regarding `configure.ac` I have no idea how to best check first for a
global framework and then for a local one and if `READLINE_CFLAGS` and
`READLINE_LDFLAGS` need to be extended or can be simply set.
I'm also not sure if the modified file `HsReadline.h` works now with a
global framework or if `READLINE_CFLAGS` has to be set to
`-I/Library/Frameworks/GNUreadline.framework/Headers`, too.
