SmallBASIC

SmallBASIC is a fast and easy to learn BASIC language interpreter ideal for everyday calculations, scripts and prototypes. SmallBASIC includes trigonometric, matrices and algebra functions, a built in IDE, a powerful string library, system, sound, and graphic commands along with structured programming syntax.

Building the SDL version

LINUX

Install packages

Ubuntu (25.04)

sudo apt install git autotools-dev automake make gcc g++ libsdl3-dev libfreetype-dev libfontconfig-dev xxd

Manjaro (Arch)

sudo pacman -S gcc make autoconf automake sdl3 freetype2 fontconfig pkgconf vim

Initial setup

 $ git clone https://github.com/smallbasic/SmallBASIC.git
 $ cd SmallBASIC
 $ sh autogen.sh

Build

 $ ./configure --enable-sdl
 $ make

Install (optional)

 $ sudo make install 

This will install sbasicg in /usr/local/bin

Run

 $ cd ./src/platform/sdl/
 $ sbasicg

Build the Debian package (optional)

 $ sudo apt-get install dpkg-dev build-essential debhelper
 $ make deb

WINDOWS

Install tools: https://www.gtk.org/download/windows.php

 $ ./configure --host=i686-w64-mingw32 --enable-sdl
 $ make

Cross-compiling for Windows under Linux

 $ sudo apt-get install mingw-w64
 $ ./configure --host=i686-w64-mingw32 --prefix=/devsw/mingw --enable-sdl

Note: requires building SDL2 and freetype-2 into the prefix folder

MacOSX

Install packages

Open the terminal window, then type the following commands at the prompt:

$ brew install sdl2
$ brew install freetype
$ brew link --overwrite freetype
$ brew install fontconfig
$ brew install autotools
$ brew install automake
$ brew install autoconf

Initial setup

$ git clone https://github.com/smallbasic/SmallBASIC.git
$ cd SmallBASIC
$ sh autogen.sh

Build

$ ./configure --enable-sdl
$ make

Run

$ cd /src/platform/sdl
$ ./sbasicg

Building the non-graphical console version (cygwin or linux)

 $ ./configure && make

Windows 32 bit mingw console:

 $./configure --host=i686-w64-mingw32 && make

Windows 64 bit mingw console:

 $./configure --host=x86_64-w64-mingw32 && make

Building web-server sbasicw

Linux

Install microhttp library

Ubuntu

 $ sudo apt install libmicrohttpd-dev

Manjaro

 $ sudo pacman -S libmicrohttpd

Build

 $ ./configure --enable-web
 $ make

Building the Android port

1. Setup .bashrc

export PATH=$PATH:~/android-sdk/depot_tools:~/android-sdk/android-sdk-linux/platform-tools/
export ANDROID_SDK_ROOT=~/android-sdk/android-sdk-linux
export TARGET_DEVICE=arm
export PLATFORM_PREFIX=~/android-sdk/android-ext/
export PATH=${PLATFORM_PREFIX}/bin:${PATH}
export NDK=~/android-sdk/android-ndk-r10d
export NDK_PLATFORM=android-19
export ANDROID_LOG_TAGS="DEBUG:I smallbasic:I AndroidRuntime:E *:S"

2. Build FreeType
   First, prepare the cross-compiler from the NDK:

  $NDK_PATH/build/tools/make-standalone-toolchain.sh \
      --platform=$NDK_PLATFORM --install-dir=$PLATFORM_PREFIX --arch=arm

Then use it to cross-compile the tools:

  cd freetype-2.5.3/
  CFLAGS="-std=gnu99" ./configure --host=arm-linux-androideabi --prefix=/freetype --without-zlib --without-png --without-harfbuzz
  make
  make install DESTDIR=$(pwd)

3. setup config.h

./configure --enable-android

4. Build the native activity

$ cd src/platform/andoid/jni && $NDK/ndk-build NDK_DEBUG=0
$ cd - && cd ide/android/ && ant release install

Useful adb commands for debugging:
adb shell dumpsys cpuinfo
adb shell top -m 10

Building the FLTK version

Install and build FLTK 1.4

$ cd ~/github
$ git clone https://github.com/fltk/fltk.git
$ sudo make install

Build

$ cd ~/github/SmallBASIC
$ ./configure --enable-fltk
$ make -s
