Sample not building on RaspberriPi

[janraak]

I:

1. Installed clang9
2. Installed rust
3. downloaded redis 6.0
4. cloned the redismodule-rs repo
5. tried to build following the read.me instructions.

No luck

pi@raspberrypiB:~/redis/redis-6.0.10/rust/redismodule-rs $ ./build.sh

It looks like the issue is caused by the compiler being unable to locate the stddef.h header file. Could you verify this file is part of your clang installation? On my Ubuntu it's found under /usr/lib/clang/10/include/stddef.h; unfortunately I don't have a RaspberryPI to test with.

Also, re-running the build with RUST_BACKTRACE=1 might provide a little more detail.

Issue resolved.

1. restarted my IDE(VSCODE) and started a new terminal.
2. build and run succesful
