Failed to determine the revision of the source code.
The reason may be
- this is neither a source distribution (containing the configure
script) nor a cloned Git repository,
- this is a shallow clone and no version tags are reachable,
- some required utilities (e.g., git) are missing.
Source distributions and some binaries can be found in:
http://www.nikhef.nl/~form/maindir/binaries/binaries.html
https://github.com/vermaseren/form/releases
The latest source code can be cloned by:
git clone https://github.com/vermaseren/form.git
