clang version clash - Githubissues

dhbradshaw commented 5 years ago

If I naively clone and then use cargo build I'm blocked by this:

package `clang-sys v0.22.0`
    ... which is depended on by `bindgen v0.37.0`
    ... which is depended on by `opus-sys v0.1.0 (https://github.com/rust-av/opus-rs#c7329ada)`
    ... which is depended on by `libopus v0.1.0 (https://github.com/rust-av/opus-rs#c7329ada)`
    ... which is depended on by `avp v0.1.0 `
links to native library `clang`

package `clang-sys v0.26.4`
    ... which is depended on by `bindgen v0.45.0`
    ... which is depended on by `vpx-sys v0.1.0 (https://github.com/rust-av/vpx-rs#7d2c86b4)`
    ... which is depended on by `libvpx v0.1.0 (https://github.com/rust-av/vpx-rs#7d2c86b4)`
    ... which is depended on by `avp v0.1.0 `
also links to native library `clang`

Updated now, please cargo update and confirm it is working for you :)

dhbradshaw commented 5 years ago

It worked!

Which uncovers the next bump:

lu-zero commented 5 years ago

you need to make sure you have libvpx installed. It isn't finding the pkg-config file for it.

dhbradshaw commented 5 years ago

Hmm, apt thinks that I already had libvpx5 installed (ubuntu 18.04). Do I need to switch to a different version or figure out how to point it to the installation or something?

lu-zero commented 5 years ago

Check if you have installed the devel package, the pkg-config file seems missing.

dhbradshaw commented 5 years ago

Ok,

sudo apt install libvpx-dev got me to a similar message that referred me to opus.
sudo apt install libopus-dev got me to a similar message that specified clang.
sudo apt install libclang-dev got me to this:

lu-zero commented 5 years ago

You are missing some fundamental libc headers apparently, try installing clang itself, I recall this somehow solved the problem to somebody with a similar distribution.

dhbradshaw commented 5 years ago

Does it matter what version? Autocomplete gives quite an array of options:

libclang1                libclang1-5.0-dbg        libclang-5.0-dev         libclang-common-6.0-dev
libclang1-3.9            libclang1-6.0            libclang-6.0-dev         libclang-common-7-dev
libclang1-3.9-dbg        libclang1-6.0-dbg        libclang-7-dev           libclang-dev
libclang1-4.0            libclang1-7              libclang-common-3.9-dev  libclang-perl
libclang1-4.0-dbg        libclang-3.9-dev         libclang-common-4.0-dev  
libclang1-5.0            libclang-4.0-dev         libclang-common-5.0-dev

Edit: I'll look through llvm documentation and write what I find.

lu-zero commented 5 years ago

find / -name stddef.h should get you a stddef.h in a clang-related library.

dhbradshaw commented 5 years ago

taking the suggestion to install clang at face value and following the instructions for 18.04 led me to simply doing

sudo apt update
sudo apt install clang

This got me past the remaining clang errors.

Which brought me to this:

use a nightly rust

dhbradshaw commented 5 years ago

Using nightly eliminates the feature error, but still leads to import errors:

rustup override set nightly
cargo build

Looks like the minimal opus version is wrong.

lu-zero commented 4 years ago

It shouldn't be a problem anymore, I hope.
