How can compile a chisel code? Which apps are you using? I tried to use Scala but, I got errors when I write a chisel code. Can you help me?
Chisel is scala code. You can compile it with a scala compiler -- scalac.
Usually, you use a build tool to do this for you, sbt.
You indicate the toolchain indicates there were errors when compiling your code. This is common. It's virtually unheard of to write code without errors in one go. The error should indicate what you did wrong.

I found this weird programming language that is an attempt to create the smallest possible compiler called brainf*ck, and i honestly want to try it but i don't have any knowlegde about how to compile the code.
Can you help me compiling a hello world program in brainf*ck?
I found a minimal compiler, surprisingly made by this guy in this repository.
I made this interpreter in like 40 minutes. It's under 70 lines of code and it only uses standard libraries in C.
it can be built by typing
make
you will get brainfuck.exe
i compiled this brainfuck code
cat.b
,[.,]
using
./brainfuck.exe cat.b

I'm going to learn Scala, I already have experience in programming. But I have some questions.
When I create a Project in IntelliJ there I must choose between sbt, Lightbend Project start and IDEA. What should I choose and what's the difference between them?
After I have created a Project, I have to create a Scala Class, right? Then I have to choose between Class, Object and Trait.
What is the difference between them?
3.Are there any other things they are good to know?
Best regards Lockna
The simplest thing to choose would be IDEA. IntelliJ will compile the project for you and you shouldn't have to do much to get it working. If you want to learn Scala and a popular build system at the same time, use SBT. It's going to be too much information to ingest at once though, so I wouldn't recommend it if you're an absolute beginner in Scala/functional programming.
Well, perhaps you should read about Scala. That's a Scala 101 question. It's already well documented on the internet, probably a thousand times, and it's not valuable to add another one here.

I program in Scala. I'm fairly versed.
Now, Rust has caught my eye. It looks good. Like it might be another language I would like to have under my belt.
From time to time, when I want to go crazy with types and still have compile time safety, I run into problems, one of which is type erasure.
Is there much difference between the two? Would it be easier to implement this question in Rust? Does Rust have type erasure?
PS. I hope this question is not too vague. Just want to have an overview of the main difference when it comes to types and generics.
Scala is GC language and has JVM runtime so it can tap into JVM ecosystem (clojure, java, groovy, ...), Rust is well known for it's trademark ownership approach which gives a lot more safety guarantees at compile time.
Rest of the differences can be neglected I believe.

How the Scala Programming Language run internally ?
Advantage of using Scala over Java?
Scala is compiled to Java bytecode, executed by the same JVM that runs Java programs, using the same JDK class library plus a small extra Scala runtime library.
The advantages are mostly for the programmer.

I am trying to export VLC to Eclipse and compile it from there (in Ubuntu).
There have been a number of errors mostly related to the location of some of the header files that I could fix. But now I am getting two errors that I don't know how to fix. The errors are:
unknown type name ‘pthread_rwlock_t’
unknown type name ‘pthread_spinlock_t’
both of these are used in "vlc_threads.h"
Any help is highly appreciated.
Thank you very much,
TJ
When I removed the c99 compiler option the errors went away, so this error is related to the C99 compiler option in Linux (Ubuntu).
