error: Could not compile `diesel_demo`.

ghotiphud · Nov 16, 2016

Enabling the "large-tables" feature fixes the compiler panic, but still getting warnings about _Dummy being defined multiple times.

killercup · Nov 16, 2016

IIRC, #493 aims to fix the _Dummy error

sgrif · Nov 16, 2016

Oh good, nightlies are building again. This is fixed by #493. I'll try to release tonight.

sgrif · Nov 16, 2016

As a workaround in the short term you can use an older nightly.

ghotiphud · Nov 17, 2016

That's alright. I was just walking through the getting started guide when I hit this, so I'm going to take a look at rust-postgres and check back later. Thanks for your work on this, seems like it's going to be pretty awesome!

bronson · Nov 18, 2016

I just hit this too, couldn't finish step 1 in the getting_started guide. Ah, nightlies!

Looks like rustc needs a little more time in the oven... I'll try again in a few weeks.

sgrif · Nov 18, 2016

All rust nightlies which have this issue are actually completely broken for procedural macros. It's all fixed on master, so we'll release tomorrow or the day after depending on when the nightly was rolled

bronson · Nov 18, 2016

Oh good. I'll try again in a few days.

How far back to I need to go if I want to keep going tonight? Maybe a month old nightly?

sgrif · Nov 18, 2016

2016-11-06

bronson · Nov 18, 2016

rustup toolchain install nightly-2016-11-06, thanks!

bronson · Nov 18, 2016

Hm, late oct / early nov only appear to work on Linux. Getting consistent ICEs on Mac:

thread 'rustc' panicked at 'index out of bounds: the len is 363930 but the index is 363930', ../src/libserialize/leb128.rs:47
note: Run with `RUST_BACKTRACE=1` for a backtrace.

owell, I'll try again in a few days. sgrif, just curious: which platform to you use for Diesel dev?

sgrif · Nov 18, 2016

Run cargo clean and recompile. Nightlies don't ship unless they work on all platforms. I use mac to develop primarily, and windows periodically.

bronson · Nov 18, 2016

Yep, that worked! Thanks for ignoring my attempts to give up.

nkhinchi · Nov 19, 2016

Hi, I am getting the same error on rustc 1.14.0-nightly (cae6ab1c4 2016-11-05)

error: custom derive attribute panicked
--> src/schema.rs:1:1

1 | infer_schema!("dotenv:DATABASE_URL");

= help: message: called Result::unwrap() on an Err value: StringError("Failed to load environment variable DATABASE_URL: environment variable not found")
= note: this error originates in a macro outside of the current crate

error: Could not compile diesel_demo.

I am using code from the examples directory to test diesel.

golddranks · Nov 19, 2016

@nkhinchi Do you have the .env file or the environmental variable set up? That looks more like it's missing.

nkhinchi · Nov 19, 2016

Thanks, that did the trick. I was struggling with the original error before.

sgrif · Nov 22, 2016

0.8.2 has been released with a fix

bronson · Nov 22, 2016

Right on, looks great. cargo update and everything works again.
