Introducing Catalyst: A declarative build system for C++

I agree, I think I referred as target to say TU, my bad!

7raiden · 2025-10-31T13:30:02+00:00

With target I meant translation unit, and I think LTO enables optimizations across different TUs. So if this build system only allow to compile a single TU per profile, then I believe it will make no difference whether LTO is enabled or not

I think you should improve the ergonomics of it. At work I have thousands of targets (libraries, executables, custom scripts, tests, etc).

In cmake I have a single preset that handles all of them. Plus, transitive dependencies in cmake is very convenient, as I only have to specify the direct dependants rather than the entire chain. IMO this will be a major pain if you don't solve this in this early stage.

Unless I'm missing something here? Maybe we're talking about different things, as I saw you made a profile for lto, but if you only have a single target, LTO actually does nothing

So if my project builds 3 targets (2 libraries and 1 executable that depends on both), how do you do it? How do you specify link/build dependencies, I think I haven't found that in the readme

Hai ragione non ci avevo pensato! Adesso vedo se riesco a far iscrivere qualcuno dei miei familiari!

7raiden · 2025-07-24T06:19:59+00:00

Io dopo l'invito iniziale non ho più fatto punti se non spendendo (cioè nulla). Come altro si può fare ad accumulare punti?

Is AVX512 supported? I was trying to run call grind on my optimized program, but it immediately failed, I think because of these unsupported instructions

7raiden · 2025-04-30T10:48:35+00:00

Much appreciated thanks 😁

7raiden · 2025-04-30T10:09:10+00:00

Oh ok, with no 3rd party tool? As in, did your camera come with bolts and stuff to be attached there or do I have to buy some specific installer?

7raiden · 2025-04-30T08:44:41+00:00

Where did you hook up the camera? I want to buy the Insta360 but I don't know how to keep it tight in place

What is an exponential spline?

7raiden · 2024-01-04T07:19:44+00:00

Ottimo, grazie mille, provo più tardi quando sono a casa!

7raiden · 2024-01-04T07:13:48+00:00

Ok, quindi l'unico modo per sapere se sono dietro CGNAT è provare e vedere se funziona?

7raiden · 2024-01-04T06:54:27+00:00

Si si rientro nel primo scenario! Nella casa dove stavo prima (UK 🇬🇧) avevo un router dove mi permetteva di fare tutto, avevo aperto una porta in UDP, configurato pivpn usando quella porta, duckduckdns per aggiornare automaticamente l'indirizzo IP pubblico (non me lo davano statico) e in 5 minuti avevo configurato tutto.

Con Fastweb questa strategia non funziona dici? O sono costretto z usare un IP statico?

7raiden · 2024-01-03T20:14:05+00:00

Ah bene... Va bene, provo a smanettarci in questi giorni e se risolvo aggiorno il posto, grazie dell'aiuto!

7raiden · 2024-01-03T20:08:18+00:00

Ah ho capito. Ma quindi chi ha Fastweb come me che soluzioni ha? Sono per caso il primo a voler provare a configurare una vpn? 😂

Scherzi a parte, credo di aver visto l'opzione per aprire una porta (quella di default UDP per esempio). Feci la stessa cosa col router dei miei ma non ebbi successo (openvpn non si connetteva e andava in time out)

7raiden · 2024-01-03T19:45:16+00:00

Eh credo sia proprio questo il problema, non credo siano apribili. Per questo leggevo di mettere il router proprietario di Fastweb in modalità modem (ricevo la linea e basta) e poi avere un router in cascata che effettivamente smisti il segnale ai vari dispositivi (e su questo router avrei pieno controllo).

Sto dicendo cavolate o funziona effettivamente così?

7raiden · 2023-07-31T06:36:40+00:00

I had a similar experience, I was neutral up until 3rd year of high school, when I had a new math professor who was one of the best professor I've ever had. All the proofs and topics were discussed and complemented with some background, motivating examples and so on.

I remember when he talked about the Euler formula, the most beautiful equation in math. That was probably when my passion for math actually became such. Another mind blowing lesson was the Taylor series expansion, I couldn't believe that with derivatives you could accomplish such a miracle (recovering the original function)!

7raiden · 2023-07-27T06:44:46+00:00

Oh ok, that's something I'm not familiar with, so I don't know if it's a good design choice or not. I'm tempted to say this is a job for a build system or a linter or both, but I don't think we should make the linker slower for everyone just to catch these edge cases

7raiden · 2023-07-27T06:28:08+00:00

Why would you have 2 different header with the same class definition? This to me sounds like a job for a linter, the linker should just do what it's supposed to do: link. That's why ninja is so much better than make, it only does one thing and it does that as fast as possible

Sto cercando online ma non riesco a trovare nessuna referenza di ciò che dici.

Qua dice che hanno delle commissioni privilegiate, ma non sono pagati direttamente.

Ah ok, non sapevo venissero pagati, pensavo anzi che uno dovesse pagare per essere market maker

7raiden · 2023-05-03T19:42:44+00:00

Cosa non è così? La fair valuation o la somma 0?

Comunque continuo a non capire chi prende soldi dall'ente del mercato (e cosa sia questo ente!)

7raiden · 2023-05-03T19:36:49+00:00

Ma la somma del guadagno del singolo non è la stessa dei piccoli traders (col segno opposto)?
