Compile runtime hanges over ten mins about substrate-node-template HOT 6 CLOSED

It seems less likely to occurs if build from a fresh node template.

On what type of machine are you building? How long does the build take until that point?

Rust isn't particular quick with the compiling at the moment and opaque to the person in front, at this step we are actually building the project twice: once natively and once in wasm. So at some step in between it appears as if nothing happens and that can take up to half the total build time – if the other part took e.g. 10minutes then this process might take another 10min without any indicator of process (other than the CPU pumping hard).

Hi, I have encountered this problem as well. Question: are you trying to build a "fresh" node template or is this something you've been hacking on for a while? I think I encounter this problem only in the latter circumstance. Can you try running cargo clean and rebuilding? Unfortunately it means you will have to start the build the scratch, but this is the kind of thing that has helped me in the past.

1. It seems less likely to occurs if build from a fresh node template.
2. The project I am working on is relatively large, the process I experience was that building until runtime crate, hangs for some time, then I ctrl+c to abort the compiling process. Finally, cargo clean and rebuild, it might be ok. Too much time wasted ... you must know.

@gnunicorn, @bkchr - is this a situation that either of you is familiar with?

Sorry for the late reply.

It takes 20 minutes to finish cargo check the raw substrate-node-template on this machine. Thank you all for your reply, I close this issue.
