Q1. how to get a nix development environment that works
|
|
|
|
1.
|
|
1. nix stdenv = gcc12Stdenv (see mkderivation.nix)
|
|
2. baseInputs has gcc (but probably doesn't need it)
|
|
3. devInputs has llvmPackages_16.clang-unwrapped
|
|
|
|
This leads to env with
|
|
CC=gcc
|
|
CXX=g++
|
|
NIX_CC=/nix/store/$hash-gcc-wrapper-12.3.0
|
|

To build, need to tell cmake to use gcc:
|
|
cmake -DCMAKE_CXX_COMPILER=$(which g++) -DCMAKE_C_COMPILER=$(which gcc) path/to/src
|

Q2. how to add a dependency to github workflow
|
|
|
|
comments.
|
|
1. workflow configured in ./.github/cmake-single-platform.yml
|
|
2. workflow runs on ubuntu vm. see
|
|
runs-on: ubuntu-latest
|
|
in cmake-single-platform.yml
|
|
3. find a desired dependency
|
|
$ apt-cache search ${keyword}
|
|
e.g.
|
|
$ apt-cache search catch2
|
|
4. add/edit install step to ./.github/cmake-single-platform.yml
|
|
- name: Install catch2
|
|
run: sudo apt-get install -y catch2
