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

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
