Decimal BASIC for Linux (Intel)
We provide with an ISO Full BASIC language system that works on Gnu/Linux (x86).
This program implements almost all of the core module and the graphics module of ISO Full BASIC.
It has not been conformed with the standard, whereas there are very few differences.
All graphics commands prescribed in ANSI Full BASIC are implemented with slight incompatibility on behavior.
Most part of the modules module and the individual character input module for Full BASIC are implemented, too.
This page deals with Intel x86_64 or AMD64 based Linux.
For ARM based linux, use BASIC Generic.
Notice.
Do not confuze AMD64 with ARM64.
Decimal BASIC for Linux(x86_64) ver. 8.1.5.4 (64bit GTK2 Edition)
Download BASIC8154En_Linux64.tar.xz.
Gtk2 version requres gtk2. If basic does not launch, install gtk2.
In Fedora 41, type in the terminal
sudo dnf install gtk2
In Manjaro Linux Gnome, Type in the terminal
sudo pacman -S gtk2
Trouble Shooting
Start a terminal in the folder where basic is located and run
./basic
This may give you some information.
Known faults.
The Debug window may be able to be minimized or maximized in some environment.
Gtk2 version do not perform clipping for printer.
Decimal BASIC for Linux(x86_64) ver. 8.1.5.4 (64bit Qt5 Edition)
Download BASIC8154En_Linux64_Qt5.tar.xz .
Qt5 vesion requires Qt5Pas library.
To install Qt5Pas
do on the terminal
sudo dnf install qt5pas
on Fedora, or rpm based distributions.
do on the terminal
sudo apt install libqt5pas1
on Ubuntu, or deb based ditributions.
To launch BASIC, type on the terminal
cd BASIC81En
./basic --platform xcb
Trouble shooting
If it does not start or there is a problem, right-click in the BASICEn folder and select "Open in Terminal" or "Open in Console" to open a terminal and start it from the terminal with
./basic
and check the error message.
(1) undefined reference to `QGuiApplication_setFallbackSessionManagementEnabled'
or … undefined symbol: QPrinterInfo_availablePrinterNames
This may occur in Debian 12.
Get the latest version of Qt5Pas.
The latest version of Qt5Pas seems to be V1.2.16 in
davidbannon libqt5pas .
Click on “Show all 22 assets” in assets to find it.
The required Qt5pas library and installation method are the same as the Qt6 version below.
In the downloaded folder, run the following command from a terminal:
sudo apt install ./libqt5pas1_2.16-4_amd64.deb ( Ubuntu, Linux Mint, etc. Debian-based )
sudo dnf install ./libqt5pas-2.16-4.x86_64.rpm (Fedora, etc. RedHat-based )
(2) error while loading shared libraries: libQt5Pas.so.1: …
The Qt5Pas library is not installed properly.
(3) QSocketNotifier: Can only be used with threads started with QThread
In this case, run
./basic --platform xcb
from a terminal .
Or, when logging in, if a gear icon 
appears in the bottom right corner when entering the user name, select the side that includes “on Xorg”.

Known fault
In Fedora41, Ubuntu24.04, etc., the graphics window, debug window, etc. are not output in the specified position in case launched without "--platform xcb".
Decimal BASIC 8.1.5.4 (x86_64) Qt6 
Download BASIC8154En_Linux64_Qt6.tar.xz
Install Qt6PAS
On the terminal, type
sudo dnf install qt6pas on Fedora,
sudo apt install libqt6pas6 on Ubuntu,
sudo pacman -S qt6pas on Manjaro Linux (Xfce, Gnome) .
Otherwise,download the file needed for executing following,
Download LibQt6Pas Pre-Built Packages Assets，
Type on the terminal
on Ubuntu or Debian based distributins,
sudo apt install ./libqt6pas6_6.2.10-1_amd64.deb
on Fedora or RedHat based distributions,
sudo dnf linstall ./libqt6pas6-6.2.10-1.x86_64.rpm
(numerals 6.2.10-1 may be alterd in future).
To launch BASIC, type on the terminal
cd BASICEn
./basic --platform xcb
Known Fault
Graphics window or text window appears incorrect position, and they may hide behind existing windows in Fedora41, Ubuntu24.04 and so on, in case launched without "--platform xcb".
