update build commands

[AMITKESARI2000]

To build regular cardioid:

spack diy cardioid

gives error from spack:

==> Error: diy is not a recognized Spack command or extension command; check with `spack commands`.

Upon digging spack issues on its GitHub, I found diy has been updated to dev-build (github link)

So, i used spack dev-build cardioid but still got error message for using it without a version number.

==> Error: spack dev-build spec must have a single, concrete version. Did you forget a package version number?

What am i doing wrong? Please help. Thanks.

Run spack dev-build [email protected]

You need to give it a version number. I'm not too familiar with Spack, but I believe the version number can be any number. My guess is the version number is for you to denote between different installations of the applications. It does not seem the application cares what value you set.
