Optimized bash script compilation of QB64 for Linux

[Coolman]

This script was located in this post : why the qb64 editor is slow under linux

to simplify the updates, I created this dedicated post.

after reading some information about gcc, i decided to use the -O3 compiler option. it's a good compromise between security and speed.

if this is your first installation of qb64, it is advised to run the script setup_lnx.sh to install the package dependencies necessary for qb64...

this script allows to insert the -O3 compiler option of gcc g++ to optimize qb64. the original files are saved. i removed some useless sections of the original script setup_lnx.sh. download the source code of qb64, unzip, put the script in the directory where is setup_lnx.sh, make it executable and run it. the processing is automatic. if the compilation was successful, the qb64 executable will be created:

compile_qb64.sh

Code: (Select All)

#!/bin/bash
# QB64 Installer
# Argument 1: If not blank, qb64 will not be started after compilation

dont_run="$1"

#This checks the currently installed packages for the one's QB64 needs
#And runs the package manager to install them if that is the case

#Make sure we're not running as root
if [ $EUID == "0" ]; then
  echo "You are trying to run this script as root. This is highly unrecommended."
  echo "This script will prompt you for your sudo password if needed to install packages."
  exit 1

note that this script is not compatible with version 0.7.x of qb64. i don't have time to modify it for the moment. i will continue to use version 0.5.0...
