I need to specify a folder with object files so that I can just specify the .o files.
Simple Sorcerer
it would simplify the makefile a bit
Simple Sorcerer
No one needs to link object files by themselves
Maybe I don't understand you. Write a simple command to compile the main.c file with compilation of object files to the build folder
Simple Sorcerer
I thought about it and realised it wouldn't simplify the makefile.

What kind of compiler do I program with C++ for Windows?
...
I couldn't find a source related to about
Manav
I'd suggest making a toy language first then making its compiler rather than trying to use C++
Manav
Go for a simpler grammar so you don't get bogged down by unnecessary details.

I know C++, but I'm wondering what kind of file is translated into system code
Manav
I know C++, but I'm wondering what kind of file is translated into system code
You know way too little to even ask a proper question.
Try making a small language first, it's parser, etc. You'll understand how to generate a syntax tree, then transforming it into instructions.
Manav
After that you can come and ask here for help regarding makimg a C++ compiler and we'll help you
Manav
My English is bad
It's not english that's the problem my friend. I understood what you meant to do the 2nd time.
...
Manav
Can you suggest a source?
Find a course online which creates a toy language. You'll find plenty of resources online. There are books on compiler architecture which will teach you exactly what you want to know.
Manav
the books that i know are quite old but it should still be usable:
1. https://www.amazon.co.uk/Advanced-Compiler-Design-Implementation-Muchnick/dp/1558603204
2. https://www.amazon.co.uk/Modern-Compiler-Implementation-Andrew-Appel/dp/052182060X
Manav
Maybe other members can suggest better ones
Manav
here's a light read to get you introduced to the concept, https://www.freecodecamp.org/news/the-programming-language-pipeline-91d3f449c919/ it's decent-ish _-_

Uhh.. compiles to mips 🫠
Oh well
Simple Sorcerer
Oh, I don't know anything about compiler creation, but I have an idea that it must be made somehow on top of assembly language.
Simple Sorcerer
I am only superficially familiar with ELF and EXE, but I think if you know their architecture, you can already do something useful.
Antonio
guys I need help. Let me start by saying I'm new to programming. do you have any advice on where to learn, for example ieterative loops, which if I have 2 fors nested with a while I get lost following the logic.
Antonio
And where can I learn the basics skills, for example to choose the best iterative loop
Antonio
Simple Sorcerer
Stuff like that
For future reference, the simpler the code, the better it is. simple code = minimum errors.
Simple Sorcerer
Try using functions somehow. there is a while for every function

I'm sure this way you won't lose your logic. but it depends more on the situation.

It can also be useful to simply think about how to avoid or simplify cycles.

No you can write a compiler in any language that produces a native executable.

My work is very boring.

How to make money in your spare time?

I have no creativity!

I only know how to program

For example?

Yeah but how do I think about simple solutions
Jose
Yeah but how do I think about simple solutions
Think about the 7+-2 rule:
The human brain at short span only can handle an average of 7 things.
If your code needs to store mentally 5 things, it's hard, but ok (don't think your coworker is Sheldon Cooper, think about a Ditto in front of a keyboard).
If your code needs to store mentally 7 things or more, your code needs to be modified as soon as possible.
Jose

A simple trick works for me is draw. Grab a pencil and start drawing boxes with simple responsabilities inside of them.
Do you need to open a file or do you need to store in RAM all your configuration file? The second one is not simpler than the first. In fact, the second one contains more than one responsability inside, for example.
(The GTA online bug root was like this, in short terms)

Or just use malloc

Guys how does the compiler sees passing functions as template arguments
𝔖𝔞𝔯𝔬
I looked at stack overflow but I had some isssues in understanding this concept
𝔖𝔞𝔯𝔬
Will the compiler actualy optimize it? Or it would compile it as a simple function pointer passed in as argument
Antonio
Antonio
But I was searching for list of exercises that gradually taught me the loops
Manav

Depends on how the argument is passed. The template instantiations happens before when compiling the translation unit.
Antonio

Its ok even if they are only logic problem, so without the need to code

You can actually see this in action by generating a map file from the linker.
Though i still don't fully understand your question

What happens when you make template<funcionType function>
void wrapper(){
function();
}
Jose

void wrapper(){
function();

Expand the example a bit, please
Manav

That depends on how you instantiate it

typedef void (*functype) (void);
void funcion(){
}
wrapper<function>()
Manav
typedef void (*functype) (void);
void funcion(){
}
wrapper<function>()
that's an incomplete example, gimme a sec
Manav
typedef void (*functype) (void);
void funcion(){
}
wrapper<function>()
void my_function() { std::cout << "Hello\n"; }
typedef void (*funtype) (void);
template <typename F> void fun() {
F f = my_function;
f();
}
template <typename F> void fun2(F f) { f(); }
int main()
{
fun<funtype>();
fun2(my_function);
}
consider this one
Manav
Look into main, how the two template functions are instantiated
Manav
Lemme generate a map file so you can see how the linker sees it.

I am writing from iPhone😭
I just had this little doubt it must be more complicated that i thought

Mangled names on my computer
??$fun2@P6AXXZ@@YAXP6AXXZ@Z

Manav
The function signatures are:
void fun2<void (*)()>(void (*)());
void fun<void (*)()>();
void my_function();
Manav
You can take a look at the function signature, for fun2,
The argument passed is void (*)(), function pointer
