  • dotnet format (5.1 or higher)

support compilers

  • .NET Core (3.x or higher)
  • for cfd build

Note

Git connection:

Git repository connections default to HTTPS. However, depending on the connection settings of GitHub, you may only be able to connect via SSH. As a countermeasure, forcibly establish SSH connection by setting CFD_CMAKE_GIT_SSH=1 in the environment variable.

  • Windows: (On the command line. Or set from the system setting screen.)
set CFD_CMAKE_GIT_SSH=1
  • MacOS & Linux(Ubuntu):
export CFD_CMAKE_GIT_SSH=1

Ignore git update for CMake External Project:

Depending on your git environment, you may get the following error when checking out external:

  Performing update step for 'libwally-core-download'
  Current branch cmake_build is up to date.
  No stash entries found.
  No stash entries found.
  No stash entries found.
  CMake Error at /workspace/cfd-core/build/external/libwally-core/download/libwally-core-download-prefix/tmp/libwally-core-download-gitupdate.cmake:133 (message):


    Failed to unstash changes in:
    '/workspace/cfd-core/external/libwally-core/'.

    You will have to resolve the conflicts manually

This phenomenon is due to the git update related command. Please set an environment variable that skips update processing.

  • Windows: (On the command line. Or set from the system setting screen.)
set CFD_CMAKE_GIT_SKIP_UPDATE=1
  • MacOS & Linux(Ubuntu):
export CFD_CMAKE_GIT_SKIP_UPDATE=1
