ctpv: config:1:2 cannot handle character:

[sbzi1020]

I'm trying cptv on Fedora Linux Asahi Remix 40 aarch64 on the Apple MacBook Air (13-inch, M2, 2022), linux kernel version is Linux 6.9.6-400.asahi.fc40.aarch64+16k.

Here is the installation process:

#
# Install dependencies for `libmagic` and `libcrypto`
#
sudo dnf install file-libs file-devel openssl-devel

cd ~/temp
git clone --depth=1 [email protected]:NikitaIvanovV/ctpv.git
cd ctpv
make
sudo make install

Compile and install without error:

But it can't preview any text file with this error: ctpv: config:1:2 cannot handle character: ?

bat works fine.

We can't really help unless you post the content of your config file. Also, do you get any errors when running ctpv -l?

I get the same issue on a nix vm on a apple M2

my config is as following, cut from a nix module I wrote for it:

        commands = {
          dragon-out = ''%${pkgs.xdragon}/bin/xdragon -a -x "$fx"'';
          editor-open = ''$$EDITOR $f'';
          mkdir = ''
          ''${{
            printf "Directory Name: "
            read DIR
            mkdir $DIR
          }}
          '';
        };

        settings = {
          drawbox = true;
          hidden = true;
          preview = true;
          icons = true;
          mouse = true;
        };

        extraConfig = ''
          set previewer ctpv
          set cleaner ctpvclear
          &ctpv -s $id
          &ctpvquit $id
        '';

      };

Running the command you suggested yields the following:

sophie@nixArmVM ~> ctpv
/etc/profiles/per-user/sophie/bin/ctpv: config:1:2: cannot handle character: �
sophie@nixArmVM ~ [1]> ctpv -l
/etc/profiles/per-user/sophie/bin/ctpv: config:1:2: cannot handle character: �
sophie@nixArmVM ~ [1]> 

based on that the only other user having this issue has the same device as me I assume its aarch64 related or smth.

You seem to have posted part of your lfrc rather than your ctpv config. Those settings you are showing are settings for lf, not for ctpv.

You can usually find your config in ~/.config/ctpv/config

I never configured ctpv, it's config is empty

I encountered the same issue on my android phone (on termux), but the warning I got is slightly different than yours.
char is unsigned by default on ARM. Try adding -fsigned-char to your compiler flags and see if you still get warnings.
