Building in Unbuntu fails

[afl5c]

Trying to build in Ubuntu (within Docker) and I get this:

checking for ANSI C header files... yes
checking for keypad in -ltinfo... no
checking for refresh in -lncursesw6... no
checking for refresh in -lncursesw... no
checking for addnwstr in -lncurses... no
configure: error: You may want to use --disable-unicode or install libncursesw.

libncurses5 is already the newest version (6.0+20160213-1ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Is it because only the latest ncurses is supported?

Would it be possible to provide binaries for dit? Or a Docker image? I just want to try it out but seems like a hassle to build/compile.

You need the dev package for ncurses when compiling (I think it's called libncurses-dev on Ubuntu)

Oh okay thanks, that is the correct package name. I installed it, and it fixed the "keypad in -ltinfo" check, but not the other ones:

checking for keypad in -ltinfo... yes
checking for refresh in -lncursesw6... no
checking for refresh in -lncursesw... no
checking for addnwstr in -lncurses... no
configure: error: You may want to use --disable-unicode or install libncursesw.

I tried "--disable-unicode" and ./configure was able to finish, and I was able to compile (with "make" and "make install"). However, I'm not sure how to run dit, haha. If I do

• ./dit
• dit
• dit --help
• dit hello.txt

...nothing seems to happen. The executable appears to start and block for input, but nothing appears on the screen. I am able to exit with ctlr-c:

root@dd1e4eaad0fb:/dit-0.6# dit
^C
root@dd1e4eaad0fb:/dit-0.6# ./dit
^C
...

I probably won't have time to look into this more, so I'll just close the thread. But just letting you know in case you want to investigate further.
