[email protected] error

When i use cargo build --release there's 2 errors of packages at compile time: (I already tried to fix it using cargo add clang-sys but it doesn't work )

error:

`The following warnings were emitted during compilation:

You will have to install gcc as well in addition to clang.

[MateoEmilio1]

I already have it installed

[vbhattaccmu]

@MateoEmilio1 can you kindly share your OS and the rust toolchain version. I will help you install it.

[MateoEmilio1]

@vbhattaccmu of course! Ubuntu 22.04.3 LTS

Toolchain: rustup 1.27.0

rustc 1.77.1 cargo 1.77.1

[vbhattaccmu]

@MateoEmilio1 can you confirm if you have libclang-dev installed? You can install by apt-get install libclang-dev and then try building the binary.

[vbhattaccmu]

@MateoEmilio1 were you able to run the client? Please let me know if apt-get install libclang-dev fixed the errors
