Error when running make? (maybe user error?)

[Mikea1985]

I tried running ncursesw5-config --cflags and putting the output in the makefile to have CURSES_LIB=-I/usr/include/ncursesw instead what was in there, but that just gives a different error message:

Same happens if I use the output of ncursesw6-config --cflags instead.

Does it help if you add -L<output of ncursesw6-config --libdir> <output of ncursesw6-config --libs ? (You could probably use backticks in the makefile, I just can't put them in here since Markdown uses them for code highlighting..

[Mikea1985]

Thanks for the prompt reply. No, adding that does not seem to change the error message. Although, I'm not sure where you want the backticks you mention...

I got it to build (in a Ubuntu 16.04 Docker container) with:

apt-get install -y git libncurses5-dev libncursesw5-dev gcc build-essential
mkdir ~/git_find_orb
cd ~/git_find_orb
git clone https://github.com/Bill-Gray/lunar.git
git clone https://github.com/Bill-Gray/sat_code.git
git clone https://github.com/Bill-Gray/jpl_eph.git
git clone https://github.com/Bill-Gray/find_orb.git
cd lunar && make && make install && cd ..
cd jpl_eph && make && make install && cd ..
cd lunar && make integrat && make install && cd ..
cd sat_code && make && make install && cd ..
cd find_orb && make && make install

Both libncurses5-dev and libncursesw5-dev needed to be installed.

[Bill-Gray]

Hmmm... libncurses5-dev and libncursesw5-dev are separate packages. You mention having the former installed. Do you have the latter (the wide-character/Unicode variant of ncurses)?

It looks to me as if you've got things partly set up to make use of the wide-char version, so it's defining all the Curses functions with wide-char attributes. Then when it goes to actually link to the library, it's not finding those functions; it's just finding the 8-bit Curses functions. I think. I'd bet that if you install libncursesw5-dev, things will improve... at the very least, that's a "necessary, though perhaps insufficient" criterion.

[Mikea1985]

Thanks Bill-Gray! Installing libncursesw5-dev did the trick. I honestly have no idea what I could have done to have gotten things partly set up to use the w-version, if the non-w version is the default. I thought I just followed the instructions. Anyway, it appears to work now. Thanks.
