[apache/incubator-teaclave-sgx-sdk] 1.1.4 enclave linker error undefined reference to `__assert_fail' without release (Issue #373)
Hi,
it looks like something changed between 1.1.3 and 1.1.4 that keeps ring (and I assume other dependencies with a `debug_assert`) from building. Here is the log output, note that I commented out the release flag in the enclave's build file (`cargo build #--release`). At the end of the log you'll find the corresponding linker error:

Check that the patched package version and available features are compatible
with the dependency requirements. If the patch has a different version from
what is locked in the Cargo.lock file, run `cargo update` to use the new
version. This may also occur with an optional dependency that is not enabled.

Whereas the same thing works in 1.1.3 (here it's just `cargo build`):

@celaus which rustc are you using? i just tested against nightly-2021-11-01 and didn't reproduce.
$ rustc --version
rustc 1.58.0-nightly (ff0e14829 2021-10-31)

I was using the respective docker images for each compile:
~~~
$ sudo docker run -ti -v (pwd):/root/sgx --device /dev/isgx baiduxlab/sgx-rust:1804-1.1.4 bash
root@23e62148b04d:~# rustc --version

@celaus reproduced. thanks!
looks like the newer compiler somehow does not include `__assert_fail`'s implementation in generated static libraries. to this end, you can `export CFLAGS="-DRING_CORE_NOSTDLIBINC=1"` to let Ring build without the `__assert_fail` dependency.
