Cannot build 'summoner-tui' about ghc-musl HOT 11 CLOSED

Thanks! I guess the solution would be to compile ncurses either with

• --with-terminfo-dirs: lookup to a few hardcoded paths with directories from the most common operating systems (/lib/terminfo, /etc/terminfo, /usr/share/terminfo)
• --with-fallback: embed some terminfo definitions directly to the library.

I'll go ahead with the first option. Hopefully I'll be able to do it via an override without sending a PR to upstream nixpkgs.

Edit: Yes, it looks like it's as easy as: ncurses.overrideDerivation (old: { configureFlags = old.configureFlags ++ [ "--with-terminfo-dirs=/lib/terminfo:/etc/terminfo:/usr/share/terminfo" ]; }). I'll test it and update the containers again.

Thanks! I'll include terminfo in the containers.

@utdemir Thank you so much!

I added ncurses library (both static and shared versions), and published -v5 images to dockerhub. I was able to compile summoner-tui statically via cloning summoner repository and applying below diff:

@utdemir Awesome news!

@utdemir Unfortunately, it doesn't work expected... It builds, but it prints some library error. When trying to run a simple command, I see:

$ ./summon-tui-linux-static new foo
  Configurations from /home/shersh/.summoner.toml will be used.
summon-tui-linux-static: setupTerm: Couldn't look up terminfo entry "xterm-256color"

When I expected to see the project scaffolding settings screen:

@chshersh I looked into it a bit, it looks like ncurses requires a terminfo database, and uses TERMINFO_DIRS environment variable to look up. This is seemingly a common problem with the use of ncurses. It's not specifically about static linking, but since installing ncurses for dynamic linking purposes also usually installs the terminfo files; it's only appears when ncurses is linked statically inside the binary and lacking the terminfo files.

I saw a related issue(fish-shell/fish-shell#1271) where they were thinking about embedding terminfo definitions inside ncurses. However the build definition from nixpkgs does not seem to have that functionality. I will take a look at adding that functionality to nixpkgs, but probably it won't be before the next weekend. However if you send a PR to nixpkgs or open an issue and it gets fixed, I can easily modify this repository to take advantage of the new functionality any time.

@chshersh Alternatively, can you check if you have a terminfo database on your system, and summoner-tui works if you set TERMINFO_DIRS accordingly? Maybe we just need to set the default lookup path in the statically linked library somehow.

from ghc-musl.

@utdemir I can confirm that specifying TERMINFO_DIRS make statically built summoner-tui succeed. The following command works on my OS (Ubuntu 18.04):

TERMINFO_DIRS=/lib/terminfo ./summon-tui-linux-static new foo

But if I understand correctly from what I read, the path to the terminfo database can be different on different machines.

@chshersh I uploaded v6 with the change I mentioned above. I also tried building summoner-tui again, and ran the resulting image on an Ubuntu container; and it worked, including the fancy TUI!

The resulting binary should be usable on common OS's, let me know if there's any other issues!

@utdemir Thanks for your work ❤️ I was able to build working statically linked executable for Summoner TUI.
