I wanted to try out the rust version of mediasoup but I’m getting some errors when building the project. Just created the project and added `mediasoup` as dependency. Nothing going on there but somehow the build fails. I have also tried to local clean cargo cache and `target` directory inside the projects directory. Any help would be awesome. **Build log:** ```auto cargo build Compiling mediasoup-sys v0.4.3 error: failed to run custom build command for `mediasoup-sys v0.4.3` Caused by: process didn't exit successfully: `/Users/baristikir/tmp/mediasoup-testarea/target/debug/build/mediasoup-sys-343b32df800a7590/build-script-build` (exit status: 101) --- stdout cargo:rustc-link-search=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib cargo:rustc-link-lib=dylib=c++ cargo:rustc-link-lib=dylib=c++abi /Users/baristikir/tmp/mediasoup-testarea/target/debug/build/mediasoup-sys-6ac05ef6f230f44d/out/out/pip/bin/meson setup \ --prefix /Users/baristikir/tmp/mediasoup-testarea/target/debug/build/mediasoup-sys-6ac05ef6f230f44d/out \ --bindir '' \ --libdir '' \ --buildtype debug \ -Db_pie=true \ -Db_staticpic=true \ --reconfigure \ "" \ /Users/baristikir/tmp/mediasoup-testarea/target/debug/build/mediasoup-sys-6ac05ef6f230f44d/out/out/Debug/build || \ /Users/baristikir/tmp/mediasoup-testarea/target/debug/build/mediasoup-sys-6ac05ef6f230f44d/out/out/pip/bin/meson setup \ --prefix /Users/baristikir/tmp/mediasoup-testarea/target/debug/build/mediasoup-sys-6ac05ef6f230f44d/out \ --bindir '' \ --libdir '' \ --buildtype debug \ -Db_pie=true \ -Db_staticpic=true \ "" \ /Users/baristikir/tmp/mediasoup-testarea/target/debug/build/mediasoup-sys-6ac05ef6f230f44d/out/out/Debug/build The Meson build system Version: 0.61.5 Source dir: /Users/baristikir/.cargo/registry/src/github.com-1ecc6299db9ec823/mediasoup-sys-0.4.3 Build dir: /Users/baristikir/tmp/mediasoup-testarea/target/debug/build/mediasoup-sys-6ac05ef6f230f44d/out/out/Debug/build Build type: native build Project name: mediasoup-worker Project version: undefined C compiler for the host machine: cc (clang 13.0.0 "Apple clang version 13.0.0 (clang-1300.0.29.3)") C linker for the host machine: cc ld64 711 C++ compiler for the host machine: c++ (clang 13.0.0 "Apple clang version 13.0.0 (clang-1300.0.29.3)") C++ linker for the host machine: c++ ld64 711 Host machine cpu family: aarch64 Host machine cpu: arm64 Downloading openssl source from https://www.openssl.org/source/openssl-3.0.2.tar.gz A fallback URL could be specified using source_fallback_url key in the wrap file meson.build:162:0: ERROR: could not get https://www.openssl.org/source/openssl-3.0.2.tar.gz is the internet available?

make sure you have python 3 and pip install as well ---

I only see the following error, error [SSL: CERTIFICATE\_VERIFY\_FAILED] certificate verify failed: unable to get local issuer certificate. Are you setting things up correctly? 🙂 ---

Thanks for the replies! Yes figured out that it was caused by the python installer and the openssl certificate. Tried this solution here and worked for me since then. > ---

not sure why you needed to do that, but ensuring the right version of python and pip is the key really… but yeah good to hear you sorted it out
