Issue
The contrast-agent.log lists the following error:
configure: error: C compiler cannot create executables
See `config.log' for more details
Cause
This is likely a system issue on systems running Mac OS with the installation/configuration of the XCode C libraries.
Resolution
To install XCode C libraries, run
xcode-select --install
and ensure proper XCode tools are available.
Next, run
gcc
and ensure the license has been accepted.
If this does not address the problem, please collect the pip config.log.
To prevent pip from cleaning up the temporary buld directory, it may be required to run pip install with the --no-clean option in order to retrieve the config.log.</class="note></class="note">
