i'm not completely helpless though i feel that way when i try a project from the web to compile under xcode. my projects have been "to the metal" with assembler, pascal, basic a touch of c and c++. i've used scripts and am passingly familiar with terminal commands (what i used to call DOS, no GUI). i've some udemy courses lined up and have seen the stanford ios. in the meantime i thought to practice by downloading some neat looking ones from the web. then i'm lost. compiling always starts with a signing error which leads to learning how to debug in xcode. BTW: as many tutorials as there are they haven't 'worked' for me. there's a step missing i'm supposed to know and don't. i need something simple. as an aside the best how to book i've ever read was "Assembly Lines" which was a compilation of articles written for BYTE magazine. It was so easy to learn assembler, then move on. anyway, take aircrack-ng a neat looking app. But the first it will say that BIGL.H is missing. There's a fix using an obscure GIT code to recurse the source as it's cloned. Unfortuantely i run into a problem in setting the location xcode expects to find the file. in the source it's <bigl/bigl.h>. I'm familiar with includes but t hat syntax for location is unfamiliar. It would help to get a reference to how to step through each error. I've stumbled into it and yet have to look through multiple tabs or screens to find the exact red shaded area. Before you say RTFM, no t he help is abysmal. So it's 1 - what directory structure should i use or how do i correct for a 'lost' file 2 - how do i switch between the gui and command line ? right now the path is command line but the script command "build" won't work 3 - how, step-by-step, do i follow each reported error Or where can i find a very direct debugging tutorial

I have a program that has the original script to call for "Build". In terminal it returns "unknown command". So I tried XCodeBuild and get this xcode-select: error: tool 'xcodeBuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance How do I do this ?

where can i post questions about containers ?I'm trying to understand the effect of addition OS container voumes within the container. For example to create a dual boot mojave/catalina how can i make sure that the same data directory is used for different version os ?

does anyone have 'besr practices' in creating dual boot with mojave ?with safe boot, createinstallmedia and security level prohibits boot8ng from external drive, i want to account for changes here. also keeoing directories from users in synch between finder versions.

Becoming a code developer after an ibookeloping a dual boot systs developer has been overwhelming. For instance developto either./ So who can we ask questions about being a developwer, installing the software, butnot code questionsing a dual boot systeml, then data migration. and permissions. Now tech support can't answer beta questions and seems the dev team doesn't care
