cannot link core 1.136.1

[r10s]

even though 1.136.1 reverts bumping the toolchain, there is an error similar to #2969 :

log: https://gist.github.com/r10s/b6a3ad2abce3f392ef263e0aad8855cc
rust-toolchain: 1.72.0 (unchanged)
build-environment: macOS

i double checked and tested 1.135.0 in the same environment, ran ./script/clean-core.sh and also tried to clean other caches (cargo clean), but no success :/

as openssl pops up in the log, maybe deltachat/deltachat-core-rust#5319 is related?

ios has lots of warnings with 1.136.1, maybe related, maybe sth. else deltachat/deltachat-ios#2104

deltachat/deltachat-core-rust#5319 is not related, it is a problem with nix turning files into symlinks, not cloning submodules etc., could not be related. That issue is about compilation and this issue is about linking to libc.

You don't have any RUSTFLAGS in your environment or anything similar? Do you have ~/.cargo/config or ./.cargo/config?

Nightly also failed to build on Linux with Rust 1.76.0, so I will debug it now. Will downgrade to Rust 1.72 and see if it helps.

EDIT: fails with Rust 1.72 and core 1.136.1:

I am building inside nix develop shell.

Looks like in commit deltachat/deltachat-core-rust@ddc2704 dependency cc got upgraded from 1.0.83 to 1.0.89 and lost its libc dependency.

[link2xt]

For Android builds cc 1.0.83 works. 1.0.84 and 1.0.85 are yanked. With 1.0.86 it fails to build.

Downgraded cc:
deltachat/deltachat-core-rust@02d6833

Will tag core 1.136.2 after testing another time.

I tagged 1.136.2

[r10s]

thanks a lot for fixing! with 1.136.2 everything compiles and links smoothly again - also the deltachat-ios warnings of deltachat/deltachat-ios#2104 are gone
