while there will be other compiler s which will convert language to IR.

while there will be other compiler s which will convert language to IR.

thats the spirit

funny, I just saw that there is a LLVM ir -> javascript compiler :D

TypeScript uses LLVM to compile to JS Or Kotlin uses LLVM to compile to native machine code

So the job of LLVM is to convert IL to ASM.

Not quite

LLVM runs some general optimizations on code in its IL

TypeScript uses LLVM to compile to JS Or Kotlin uses LLVM to compile to native machine code

Not quite but I'm sort of convinced about how things r working.

So it is optimising the intermediate code

The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Despite its name, LLVM has little to do with traditional virtual machines. The name "LLVM" itself is not an acronym; it is the full name of the project. LLVM began as a research project at the University of Illinois, with the goal of providing a modern, SSA-based compilation strategy capable of supporting both static and dynamic compilation of arbitrary programming languages. Since then, LLVM has grown to be an umbrella project consisting of a number of subprojects, many of which are being used in production by a wide variety of commercial and open source projects as well as being widely used in academic research. Code in the LLVM project is licensed under the "Apache 2.0 License with LLVM exceptions" The LLVM Core libraries provide a modern source- and target-independent optimizer, along with code generation support for many popular CPUs (as well as some less common ones!) These libraries are built around a well specified code representation known as the LLVM intermediate representation ("LLVM IR"). The LLVM Core libraries are well documented, and it is particularly easy to invent your own language (or port an existing compiler) to use LLVM as an optimizer and code generator.

And then there's so called backend

TypeScript uses LLVM to compile to JS Or Kotlin uses LLVM to compile to native machine code

So it is optimising the intermediate code but what about conversion the machine language.

And then there's so called backend

And backend compiles LLVM IL to target platform

I guess LLVM is doing that too

And target platform could be machine code, JavaScript etc

LLVM Core compiles it to binary for the chosen cpu architecture

*converting to machine lang. Typo there.

yeah,... but lets say, @unterumarmung , that this js output is rather hacky and not part of the actual LLVM core, is it

the main goal of LLVM core is to generate code for a CPU

Ok, I'm not an expert Just telling what I learned :)

Got it

@unterumarmung well, you are correct, that you can compile IR to js, but that is more an "add-on"

My question is that how do I write an opengl program with visual studio code as my code editor

LLVM is huge and i don't think, that there are many people that know what you can do with it as a whole.

My question is that how do I write an opengl program with visual studio code as my code editor

My question is that how do I write an opengl program with visual studio code as my code editor

With your hands, probably?

I want to know how to do it

Turbo, at what stage are you facing problems. Could you be more specific, please

I want to know how to do it

There's lot of tutorials about opengl in the internet as far as I know. What problems do you have?

With your hands, probably?

I have set up c++ with it but when I add glfw3 gdi32 and opengl

I get a message about undefined reference

okay,... are you using cmake for the build process?

No sir

1. Learn about build systems 2. Learn about compilers on your platform 3. Learn how to use opengl on your platform 4. Open the editor 5. Write some valid code using your knowledge 6. Compile your program ??? Profit

Ok sir

Turbo have you ever build a opengl program in your commandline?

by using compiler options?

No sir

I have used code block

But now I want to use visual studio code

The ui is nice

okay, then i have a task for you, are you ready?

oh wait

Yes sir

on linux, mac or win?

Anything

Windows

oh... okay...

on linux, mac or win?

Windows

ähm... i have no clue how to compile in commandline on windows :D

Ok give me your ideas on other systems maybe it will help

i'd start, using vim, to write a simple opengl hello world, as stated in online tutorials

then try and compile this one file with g++

No, you just have to learn how to use opengl on windows

No, you just have to learn how to use opengl on windows

I have some knowledge in opengl

The build process is what troubles me

i'd start, using vim, to write a simple opengl hello world, as stated in online tutorials

I don't think using vim is necessary

Turbo but you have no clue how the buildsystem works

There is a thing called Visual Studio

@unterumarmung with "vim" i mean.... any kind of bare text-editor

There is a thing called Visual Studio

Do you able to use it, Turbo?

No sir

Why not?

The network in my region is slow

I will take a very long time to download

That is why I don't have it

I think you have to do it Because there's a lot of tutorials using VS

1. Learn about build systems 2. Learn about compilers on your platform 3. Learn how to use opengl on your platform 4. Open the editor 5. Write some valid code using your knowledge 6. Compile your program ??? Profit

Or

Ok sir

Thank you

May God bless you

The first option is much easier

Well

Ok

So, wanted to ask

Turbo if you want to compile a glfw3 program, use the compileroptions: -lglfw3 -lGL -lm -lXrandr -lXi -lX11 -lXxf86vm -lpthread

that do all c and cpp compilers use LLVM as their backend

that should do the trick with the undef ref

that do all c and cpp compilers use LLVM as their backend

no. only clang does

gcc, g++

clang

Did you ever compile your program using command line, turbo?
