gbowne1 / programmernotes Goto Github PK

This set of notes really needs a web development section on:

• HTML5
• CSS3
• General web development notes
• design notes

I already started on a separate JavaScript note. Any notes on JavaScript will be only referred/referenced here.

Add a note on GCC compiler flags

-A needs an assertion
-B needs a argument
-D needs a macro name (Defines a macro with the specified name)
-F needs a path (Specifies a directory to search for header files)
-I needs a path ( Adds a directory to the list of directories to be searched for header files during preprocessing )
-J needs an argument
-L needs an argument (specifies the linking directory) (specify a directory to search for libraries during the linking phase)
-R needs an argument
-T needs an argument
-U needs a macro name (This flag is used to undefine a macro)
-d needs an argument
-e needs an argument
-g includes debug symbols
-h needs an argument
-l (lower case I) needs an argument
-o needs a file name (specifies the output files)
-l (lower case L) needs and argument (This flag is used to link against a specific library)
-u needs an argument (used in symbol linking)
-v is verbose?
-x needs an argument (used to specify the language of the input files)
-z needs an argument

Needs moar research.

Here is the launch.json as provided by IntelliSense. Also the document for launch json needs improving based on testing.

Need to add

• Importing python modules and libraries
• Python keywords
• how to run python
• Using the python repl
• Python program / app structure

I'm assuming that the linker ld is just getting confused here but I tried both capitalized flags and lowercase flags.

This is what it reports on my system.

ld -d says "no input files"
ld -g says "no input files"
ld -i says "no input files"
ld -m says "missing argument to m"
ld -n says "no input files"
ld -q says "no input files"
ld -r says "no input files"
ld -s says "no input files"
ld -t says "no input files"
ld -v reports the version
ld -x says "no input files"

ld -E says "no input files"
ld -G says "no input files"
ld -E says "no input files"
ld -M says "no input files"
ld -N says "no input files"
ld -Q says "no input files"
ld -S says "no input files"
ld -U says "no input files"
ld -V is the same as -v but reports the emulations
ld -X says "no input files"

things to document:

What uname -aimnoprsv will do in bash, and what doing those letters individually will do.

what ls -abcdfghiklmnopqrstuvx

ls -f prints only dotfiles
ls -p prints a / on directories

ls -ABCDFGHIJKLMNOPQRSTUVWXYZ works too.. somehow.

how to use find and whereis and which

how to use apt

There is a error in the description for the tasks.json file. It should look something like:

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
     "tasks": [

      "options": {},
      "problemMatcher": {

      },
      "group": "build",
      "presentation": {

        "panel": "shared"
      },
      "dependsOn": "",

   ],
 }

Make a introduction to using git and also using Git with GitHub
