Hi Alain,

Spack can’t automatically download VMD, since VMD requires that users accept a license before offering a download. Download a VMD source package, and I think Spack should be able to figure out the rest.

Subject: vmd-l: Issue install VMD 1.9.3 Spack

Dear VMD developers/users,

I am trying to install VMD 1.9.3 on my small HPC cluster with Spack. All dependencies seem to build correctly but when running the VMD install I get the following error message:

==> Installing vmd-1.9.3-tgbutsecur6xkglmkeno237xvc3rbi7p
==> No binary for vmd-1.9.3-tgbutsecur6xkglmkeno237xvc3rbi7p found: installing from source
==> Error: FetchError: Manual download is required for vmd. Refer to$> for download instructions.

/usr/local/spack/lib/spack/spack/, in do_fetch:
        1385 self.stage.create()
        1386 err_msg = None if not self.manual_download else self.download_instr
>> 1387 start_time = time.time()
        1388 self.stage.fetch(mirror_only, err_msg=err_msg)
        1389 self._fetch_time = time.time() - start_time

Attached to this email is the Spack output file. If someone could help me I would be very grateful.

Thanks in advance,

best regards
