TaskWarrior installation issue

[psel11]

Hi all,
I‘ve tried to install TaskWarrior 3.4.1 on Windows Subsystem for Linux with Ubuntu 24.04.3 LTS. During installation, I get the error:

$ cmake -S . -B build -DCMAKE_BUILD_TYPE=Release

-- Configuring C++17
-- System: Linux
-- Looking for git submodules

-- Looking for SHA1 references
-- Found SHA1 reference: 1f6e7de
-- Looking for libuuid

-- Configuring cmake.h
-- Rust Target: x86_64-unknown-linux-gnu

CMake Error at src/taskchampion-cpp/corrosion/cmake/Corrosion.cmake:1726 (message):
Failed to find a dependency on cxxbridge-cmd / cxx for crate
taskchampion_lib
Call Stack (most recent call first):
src/taskchampion-cpp/CMakeLists.txt:26 (corrosion_add_cxxbridge)

Do you have any idea how to solve the issue?

BR,
Peter

You'll need a newer Rust version -- the minimum supported version is 1.81.0

Same issue with both: current version from GitHub and downloaded task-3.4.1.tar.gz
Git submodule update has no effect:

I've tried on another machine with Mint 22.1. There, it builds perfectly without any issue.

Hm, maybe this is a different issue with the same error then. Can you run cmake with the arguments -Wdev --debug-output --trace and attach the output (perhaps in a gist)?

[psel11]

Our company policy seems to block gist....see the debug output attached as txt file.
cmake_debug.txt

/home/pselig/task3/taskwarrior/src/taskchampion-cpp/corrosion/cmake/Corrosion.cmake(1614):  message(DEBUG `cargo tree -i ${cxx_name}` returned an error: ${cxx_version_error} )

that happens twice, once each for cxx_name in cxxbridge-cmd and cxx. It'd be super-cool if CMake would not just log the message template, but expand the variables! Especially for how it's invoking cargo:

    execute_process(COMMAND ${CMAKE_COMMAND} -E env
                    "CARGO_BUILD_RUSTC=${_CORROSION_RUSTC}"
                    ${_CORROSION_CARGO} tree -i "${cxx_name}"
                    # Usage of `cxx` could be gated behind a feature. Features can use Generator expressions,
                    # so we can't really know what features we will enable when building at this point.
                    # Features should be additive though, so simply enabling all-features should work for
                    # dependency resolution.
                    --all-features
                    --target all
                    --depth=0
                    WORKING_DIRECTORY "${manifest_dir}"
                    RESULT_VARIABLE cxx_version_result
                    OUTPUT_VARIABLE cxx_version_output
                    ERROR_VARIABLE cxx_version_error
    )

is failing, but CMake is not revealing how. If you manually run, I'm guessing here,

cmake -E env CARGO_BUILD_RUSTC=/home/pselig/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/bin/rustc cargo tree -i cxxbridge-cmd --all-features --target all --depth=0

what happens? I suspect there's a full path to cargo there, maybe /home/pselig/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/bin/cargo?

Thank you! Got it working now :-)

This CMake output showed the problem: config.json could not be downloaded due to a certificate issue:

Updating crates.io index
error: failed to get cxx as a dependency of package taskchampion-lib v0.1.0 (/home/pselig/task3/taskwarrior/src/taskchampion-cpp)
Caused by:
failed to download from https://index.crates.io/config.json
Caused by:
[60] SSL peer certificate or SSH remote key was not OK (SSL certificate problem: self-signed certificate in certificate chain)

[djmitche]

I'm glad you solved it! Can you help the next person with the steps you took to fix the cert issue?

[psel11]

I've solved it the easy way and used another network without restrictions to connect to the internet. Therefore, I unfortunately can not provide additional helpful information.
