Can't build on Ubuntu (AWS EC2)

[ivnsch]

After diverse issues trying to cross-compile my project, I decided to upload a minimal version of the source to AWS and build there.

The build however always gets stuck on the aws-sdk-s3 dependency:

Building [=======================> ] 398/402: aws-sdk-s3                                                                                                                                                                                       

There are no errors or warnings and I've waited for hours, tried again with a different instance etc. - it always gets stuck there.

Building with --verbose shows this:

It builds without problems on my Mac.

How much RAM does the system it hangs on have? First thing that comes to mind for me is that if the system doesn't have a lot of memory, the compiler might be swapping a lot leading to an extremely long compile time. Our CI successfully compiles aws-sdk-s3 on Ubuntu 20.04, so not quite 22.04 but I can't imagine there would be too large of a difference there.

Is this the only way available to us to work around this problem though ? It's a bit unfortunate that we are somewhat forced to upgrade to a 10$/month instance just to compile our rust project, when our webserver could run properly on the 3.5$ or 5$ instances

EC2 and S3 have a very large API. We've considered feature-gating individual operations which would help, but I don't know if we're going to implement it. If this is a really important issue to you, could you take the time to submit a GitHub issue so we can track this?

[ivnsch]

Aah that was it! It had just 1GB, upgraded to 2 and now it finishes.

I'm hitting a similar issue, with the aws-sdk-ec2 dep on a project taking forever to build in the cloud (a GCP instance). 2 vCPUs and 8 GB of RAM, no swapping occuring to disk. Same project compiled fine on my Laptop.

CPU is maxed out on both cores. It took about 15 minutes (out of a 16 minute build) before it progressed past the aws-sdk-ec2 stage.

Hello! Reopening this discussion to make it searchable.

Guys, I am trying to build it on my PC it has 16 GB of ram but still it's crashing

[kriptonian1]

It's really getting hard for me to work this way
