Ardour5 build fails due to -lreadline

[naren....@gmail.com]

Hi,

Running
sepkg -q audio

eventually ends in ardour5 build fail.

Looking at the logs (/tmp/se/ardour5-5.12/build/config.log shows that the check for readline fails due to unreferenced tputs in readline

-------------------config.log snippet-------------
Checking for function readline
==>
#include <stdio.h>
#include <readline/readline.h>

        int main() {
        void *p;
        p=(void*)(readline);
        return 0;
}

Has anyone seen this?

I know readline depends on ncurses or termcap for tputs (per the numerous messages related to similar failures in other tools, emacs for example)

The solution would be to include -lncurses as part of the build as well but I am not sure where I go and add this.
It's not in the 'waf configure...' part from what I can see

Any help/pointers would be helpful

Cheers
