Description of bug

NOTE: I tried this recommendation, but it did not work...
https://substrate.stackexchange.com/questions/1079/no-to-substrate-wasm-fn-return-value-in-the-root-when-i-run-cargo-build-in

I built a MacOS target example successfully
I built Substrate example successfully

When I added Substate dependencies to MacOS version I get the following error:

error[E0432]: unresolved import sp_core::to_substrate_wasm_fn_return_value
--> ~/.cargo/git/checkouts/substrate-7e08433d4c370a21/f38bd66/primitives/api/src/lib.rs:80:9
|
80 | pub use sp_core::to_substrate_wasm_fn_return_value;
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ no to_substrate_wasm_fn_return_value in the root

Can this be my .toml , etc.
Note sp-core compiles but can not find. Using same version as contract pallet for testing.
Compiling sp-core v7.0.0 (https://github.com/paritytech/substrate.git?branch=polkadot-v0.9.37#f38bd667)

Various types and functions useful for interacting with substrate exist in these sp (substrate-primitives) crates:
sp-core = { git = "https://github.com/paritytech/substrate", package = "sp-core", default-features = false, branch = "polkadot-v0.9.37" }
sp_runtime = { git = "https://github.com/paritytech/substrate", package = "sp-runtime", default-features = false, branch = "polkadot-v0.9.37" }
sp_keyring = { git = "https://github.com/paritytech/substrate.git", package = "sp-keyring", default-features = false, branch = "polkadot-v0.9.37" }
sp_version = { git = "https://github.com/paritytech/substrate.git", package = "sp-version", default-features = false, branch = "polkadot-v0.9.37" }

XCM utilized for the 06_storage_iter example.
xcm = { version = "0.9", git = "https://github.com/paritytech/polkadot.git", branch = "master", package = "xcm" }

There are some types we want in the pallet crates (if we liked, we could just redefine them to save bringing these in):
pallet_balances = { git = "https://github.com/paritytech/substrate.git", package = "pallet-balances", default-features = false, branch = "polkadot-v0.9.37" }
pallet_system = { git = "https://github.com/paritytech/substrate.git", package = "frame-system", default-features = false, branch = "polkadot-v0.9.37" }

Steps to reproduce

I created Mac version of project here successfully -
https://chinedufn.github.io/swift-bridge/building/xcode-and-cargo/index.html

Added dependencies from this project which caused import error -

to_substrate_wasm_fn_return_value this is only available when the std feature is not enabled for sp_core.

[blockcowboy]

default-features = false
Yes, I have default-features = false, do i need to put standard-features = false ?

[bkchr]

I would assume that you still have std feature enabled or something. Given the things you said here it is not possible to help you, because there is no context.

I resolved the problem. I was using crate versions from examples (dated). BAD IDEA.
If I have time, I need to go back and update those examples so others do not have this problem.
I updated crate versions and added a features flag for entire Cargo.toml
Issue resolved.

Ty for reporting back!
