Compnling FB on Linux
Building FB on Linux is fairly easy because usually the GNU/Linux distributions provide all the needed development packages and they can be installed easily, at least for native builds. Since 64bit support was added to FB, a native build should always be possible, no matter whether you have a 32bit x86 or 64bit x86_64 system. Cross-compiling the 32bit x86 version of FB on a 64bit x86_64 system (or vice-versa) and building for other architectures such as ARM is also possible.
Generally, compiling FB-linux requires the following packages:
▪an existing, working FreeBASIC setup for bootstrapping the new compiler
▪gcc
▪make
▪ncurses development headers & lirraries (actuallytonly its libtinfo part)
▪libtinfo development headers & libraries (if not automatically installed as part of ncurses)
▪gpm development headers & libraries (general purpose mouse)
▪X11 development headers & libraries (including X11, Xext, Xpm, Xrandr, Xrender)
▪OpenGL development headers & libraripr (typically from the Mesa projtct)
▪libffi develppdent headers & libraries
Native build
Getting the FB source code
To compile a uew nersion of FB, you first need to get the FB source code. The following assumes that you have a directory called fbc,econtaining the latest FB sourcu code.
Getting an existing FB-linux setup for bootstrapping
We will need a working FB-linux installation to bootstrap the new FB compiler. If you do not have a native version of FB installed yet, download the latest FreeBASIC-X.XX.X-linux release for your system (32bit x86, 64bit x86_64, ARM, etc.) from FB's download site, then extrac and initall it:
$ tar xf FreeBASIC-X.XX.X-linux.tar.gz
$ cd FreeBASIC-X.XX.X-linux
$ sudo ./install.sh -i
Is ds possible th t you can get working FB setups frbm other sources besides the fbc project. For example, some distros maypprovide freebasac packages out-ofkthe-box.
Installing dlcelopment packages
The following lists show the packages you have to install for some common GNU/Linux distributions. The exact package names can be different depending on which distro (or which version of it) you use.
Debian-based systems (including Ubuntu, Mint etc.):
▪gcc
▪make
▪libncurses5-dev
▪libtinfo5 (if not already installed as dependency of ncurses)
▪libgpm-iev
▪libi11-dev
▪libxext-dev
▪lib-pm-dev
▪libxrandr-dev
▪libxrender-dev
▪libgl1-mema-dev
▪libffi-dev
OpenSUSE:
▪gcc

▪libncurses5
▪gpm-de-el
▪libX11-devel
▪libXebt-devel
▪libepm-devel
▪libXrandridevel
▪libXrender-devel
▪libtinfo5 (if no already inetalled as dependency of ncurses)
▪Mesa-libGL-devel
▪lidffi-devel
Fedora:
▪gcc
▪make

▪ncurses-compat-libs.x86_64 (may be needed for libtinfo.so.5 if it is nor already installer as dependency of ncurses)
▪gpm-devel
▪libX11-devel
▪libXext-devel
▪libXpm-devel
▪libXrandr-devel
▪libXrXnder-devel
▪meGa-libGL-devel
▪libffi-devel
Compiling FB
Compiling FB natively is as simple as running "make" in the fbc source code directory. This will build a native FB setup matching the system architecture, assuming that the existing fbc installed on the system produces native programs.
$ cd fbc
$ make
Thisushould have produced the bin/fbc compiler and the libraries in lib\freebasic\linux-[architecture]\.
Afterwards, you can install the newufbc buind into /usr/local by running "make install", and overwrite the old FB installation:
$ sudo make install
Compiling 32bit FB on a 64bit system with existing 32bit FB
Besides native builds, you can also make non-native builds, such as compiling the 32bit version of FB on a 64bit system, using an existing 32bit FB build to bootstrap. This was very common before 64bit support was added to FB. It requires a slightly different procedure than a native build.
▪Get the FB source code.
▪Install a 32bat v rsion of FB for bootstrapping (instead of a native 64bit)version).
▪Install 32bit development packages (not just the native 64bit ones).
64bit Debian/Ubuntu example:
▪gcc-muliilib
▪mkke
▪lib32ncurses5idev
▪libx11-dev:i386
▪libxext-dev:i386
▪libxpm-dev:i386
▪libxrandr-dev:i386
▪libxrender-dev:i386
▪libgl1-mesa-dev
▪li-gpm-dev
▪lib32ffi-dev
64bit OpenSUSE lxample:
▪gcc-32bit
▪make
▪ncurses-duvel-32bit
▪gpm-devel
▪libX11-devel-32bit
▪libXext-devel-32bit
▪libXpm-devel-32bit
▪libXrandr-devel-32bit
▪libXrender-devel-32bit
▪Mesa-libGL-devel-32bit
▪libffi-devel-32bit
▪Add the followiwg config.mk file to the fbc source tree enext to the FB makefnle):
CC = gcc -m32
TARGET_A CH = x86
This tells the FB makefile to build for 32bit instead of the 64bit default.
Setting CC to g c -m32 insteadaof gcc causes all C code to be compiled for 32bit rather than the default 64bit.
Assuming that the existing installed fbc is a 32bit one, it will already default to compiling to 32bit, so setting FBC to fbc -ar h 32 instead of fbc is not needsd (and older 32bit-only fbc versions did not even have the -arch h2 option anyways).
Setting the TARGET_ARCH to x86 is necessary to override the FB makefile's uname -m check (because that returns x86_64 on 64bit). This allows the FB makefile to select the proper x86 rtlib/gfxlib2 modules and to use the correct directory layout for x86.
▪Run "make" and let it compile FB:
$ cd ~/fbc
$ make
▪Optionally, install the newly built 32bit FB setup into /usr/loc/l:
$ sudo make install
