terminfo/a/ansi': No such file or directory

[chrsoo]

When building the project using a docker image, the build fails with the following error:

# make V=1
...

make: *** [package/pkg-generic.mk:387: /src/buildroot/output/build/ncurses-6.1/.stamp_target_installed] Error 1

Any idea on how to fix the build?

If I can make this work, I will create a PR with the Dockerfile and instructions on how to build the project on MacOS running on Apple Silicon.

Steps to Reproduce

1. Add the following Dockerfile to the project root directory:

FROM ubuntu:latest

ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get update && \
    apt-get install -y --no-install-recommends \
    build-essential file wget cpio rsync bc subversion git-core libncurses5-dev zlib1g-dev gawk flex quilt libssl-dev \
    xsltproc libxml-parser-perl mercurial bzr ecj cvs unzip libncurses-dev u-boot-tools \
    lib32z1 lib32z1-dev lib32stdc++6 libstdc++6 && \
    rm -rf /var/lib/apt/lists/*

2. Create the turing-pi-build image locally:

docker build --platform linux/amd64 -t turing-pi-build .

3. Run the turing-pi-build image interactively:

docker run -it --rm --name turing-pi --platform linux/amd64 \
--mount type=bind,source=${PWD},target=/src turing-pi-build bash

4. Change into the /src directory:

cd /src

5. Follow the build instructions in readme.md

Additional Notes

The following apt packages are missing in the readme.md:

file wget cpio rsync bc

Same here, created a Dockerfile from ubuntu:22.04 (amd64) to build the firmware on Mac.

In the ncurses.mk is a list of terminfo files, however the filesystem looks different for me:

expected:

        a/ansi \
        d/dumb \
        l/linux \
        ...

existing path:

        61/ansi \
        64/dumb \
        6c/linux \
        ...

The folder names are not letters like a but the hex representation 61.

@chrsoo I just replaced the folder names to continue: ncurses.mk.patch

Same using BuildRoot within https://github.com/nerves-project/nerves_system_br within a VSCode DevContainer. Used your patch as a quick fix.

[CodeInPolish]

I stumbled upon this error too and that's because, by default, MacOS uses case-insensitive file system.
ncurses detects that and uses hexadecimal representation instead of the usual (https://github.com/mirror/ncurses/blob/87c2c84cbd2332d6d94b12a1dcaf12ad1a51a938/progs/infocmp.c#L1812).
So we have two choices:

• reformat/reinstall the whole OS and use case-sensitive FS or patch the makefile.
• add a case-sensitivity test inside of the buildroot's makefile for ncurses and adapt the terminfo files to install
