unable to compile find_orb : no curses.h #30

Closed MADECICCO closed 3 years ago

MADECICCO commented 3 years ago

It seems there is no curses.h file

`findorb.cpp:40:13: fatal error: curses.h: No such file or directory

include "curses.h"`

Ubuntu 184.4.

Hmmm... that should only happen if the wide-character version of the ncurses development library, libncursesw5-dev (may be libncursesw6-dev) isn't installed. I don't remember which version is used on 18.04; either will work.

In a few places (see, for example, jpleph.cpp in the jpl_eph repo), I've made use of the has_include() directive so that I can show a more informative error message. In this case, it could be I should add something like

#if defined( __has_include) && !__has_include(<curses.h>)
   #error   \
     'curses.h' not found.  Install libncursesw6-dev (wide-character\
     version of the ncurses library) and try again;  it should work.\
    It may be libncursesw5-dev on older systems.
#endif

I've occasionally wished there was a cleaner way to tell people, "Thus-and-such dependency wasn't found; here's what to do about it." The above is pretty good, though.

Yeah, sudo apt get install libncurses5-dev libncursesw5-dev solved this issue. Thanks!
