While emerging rust it checks whether you have 9216 MiB of disk space, which is not enough for rust-1.47.0-r2. Mine wouldn't even compile with 12GB of RAM. I needed to set the amount to set the size of my RAM disk to at least 14GB to get it to compile. Reproducible: Always Steps to Reproduce: 1.emerge =dev-lang/rust-1.47.0-r2 with less than 14GB of disk space Actual Results: =dev-lang/rust-1.47.0-r2 emerged successfully Expected Results: Compilation gave an error that I ran out of disk space.
Please at least provide output of `emerge --info dev-lang/rust` The ebuild tries to do some analysis to figure out more precise space requirements and knowing what you used may be helpful to know what caused the difference.

Confirmed. rust-1.48 does not even compile in a 12GiB tmpfs but fails with "No space left on device".
Okay, summary was about rust-1.47 so I restore the original one. For the record. rust-1.47 could be built in a 12GiB tmpfs but rust-1.48 can not.
bug 753428 comes to mind?

With USE="system-bootstrap system-llvm" it seems kind of modest on my end which is what made me wonder where this 14GB came from, but results are still a bit above what's checked. Checking for at least 6144 MiB disk space [...] dev-lang/rust-1.48.0 (2020-11-25 23:26:04) * Final size of build directory: 7749408 KiB ( 7.3 GiB) * Final size of installed tree: 247112 KiB (241.3 MiB)
I have a feeling -system-llvm and amount of enabled llvm targets plays a big role here. I still haven't determined build time sizes, building different combination of flags until I determine a pattern I could use in size calc function. If I simply bump reqs to 16G a lot of people going to be PISSED ( for a good reason ).

I just compiled dev-lang/rust-1.48.0 with the system-llvm USE flag enabled on a different machine and the usage of my tmpfs was 11,6GB compared to 13,4GB when compiling dev-lang/rust-1.47.0 with the system-llvm USE flag disabled. So there's definitely a difference between with the USE flag enabled and disabled, but 9,2GB is just not enough. You'll at least need to bump it to 12GB for it to compile successfully. The fstab on which I compiled dev-lang/rust-1.48.0 with the system-llvm USE flag enabled has is the following: tmpfs /var/tmp/portage tmpfs size=12G,uid=portage,gid=portage,mode=775,noatime 0 0
it already does come calculation based on which flags are enabled ( just not which rust targets ) base requirement is 6GB right now and bumping it will bump the end result. I just don't want to bump it too much. pre_build_checks() { local M=6144 M=$(( $(usex clippy 128 0) + ${M} )) M=$(( $(usex miri 128 0) + ${M} )) M=$(( $(usex rls 512 0) + ${M} )) M=$(( $(usex rustfmt 256 0) + ${M} )) M=$(( $(usex system-llvm 0 2048) + ${M} )) M=$(( $(usex wasm 256 0) + ${M} )) M=$(( $(usex debug 15 10) * ${M} / 10 )) eshopts_push -s extglob if is-flagq '-g?(gdb)?([1-9])'; then M=$(( 15 * ${M} / 10 )) fi eshopts_pop M=$(( $(usex system-bootstrap 0 1024) + ${M} )) M=$(( $(usex doc 256 0) + ${M} )) CHECKREQS_DISK_BUILD=${M}M check-reqs_pkg_${EBUILD_PHASE} }

I've updated 1.47.0-r2 as I could, will port to other rusts as I measure numbers. It's very hard to get precise numbers due to multiple factors involved, as if we set it too high, users will be angry that ebuild dies. if we set it too low, ebuild will die mid-build due to out-of-space or out-of-ram conditions. But generally if you have 16G or less of ram - be prepared to use non-tmpfs space to compile rust (like for browsers, libreoffice and other big apps) 32G ram machines can safely compile in tmpfs, usually.
Hello Georgy, Would you mind porting your changes to rust-1.48.0? It's quite frustrating when you get out of space after hours of compiling. I suppose 16 GiB would be a reasonable requirement. Thanks in advance!
I'm hitting the same issue with 16 GB of tmpfs on rust-1.51.0.
