error[E0463]: can't find crate for `core`

I'm using Fedora 32 x86_64. using pre-installed Rustup. Set default toolchain to nightly, installed xargo as what README says.

Now when I run make, This thing happens:

after cloning the repo running make gives tihs this error:

error: failed to run `rustc` to learn about target-specific information

googling pointed to phil-opp/nightly-libcore#6

I downloaded the install-libcore.sh file to try to run it against the 3ds specification and it complain about a new linker-flavor flag missing in the 3ds.json file, so I added it and set to gcc, after it still looks like it cannot compile core:

error: Could not compile `std`.

Rust updates broke stuff.

I'd successfully compiled the template project a few times using various Rust 1.4 and 1.5 nightly builds, but it seems that something broke somewhere along the line in the 1.6 nightly and onwards.

For one, libc got changed a lot and the path to it is now $RUST_SRC_PATH/src/liblibc/src/lib.rs. I also had to manually add #![no_std] to the lib.rs file because apparently libc has some sort of conditional dependency on stdlib now, and I couldn't figure out how to pass the proper condition to use libcore instead via the rust3ds_template Makefile.

Then aside from the libc stuff, any attempt to compile the template project itself fails for some reason I haven't been able to pin down. Using the --verbose flag during compilation results in a giant spew of multiple function definition errors, and I haven't been able to figure out what's causing that. Maybe the compiler-rt.a file needs to be updated?

Using the latest version of ctru-rs

Hi, I'm trying to use the latest version of ctru-rs with this template but I get the following error when I try to compile it:

rustc: /buildslave/rust-buildbot/slave/nightly-dist-rustc-linux/build/src/llvm/lib/CodeGen/AsmPrinterDwarfUnit.cpp:724: llvm::DIE* llvm::DwarfUnit::getOrCreateTypeDIE(const llvm::MDNode*): assertion `Ty == resolve(Ty->getRef()) && "type was not uniqued, possible ODR violation."' failed.

I'm using a local version of ctru-rs but the problem also occurs when I'm using the git version.
Is there a way to fix this compilation problem ?

The ultimate goal would be to be able to be able to get involved into improving ctru-rs while being able to test it using this template.

I'm using the latest rust nightly with the latest xargo from git and devkitarm 44

Edit: setting lto from true to false in Cargo.toml allowed the compilation to succed, is it ok to disable it?

Error during the link

Hi,

I got the following error during the final link:
= note: arm-none-eabi-gcc: error: 3dsx.specs: No such file or directory

error: aborting due to previous error

error: Could not compile rust3ds-template.

Not sure why but I have the file in /opt/devkitpro/devkitARM/arm-none-eabi/lib/3dsx.specs
