NAME

fbc − The FreeBASIC compiler

DESCRIPTION

Compiles FreeBASIC source code files (*.bas) to native code.

SYNOPSIS

fbc [options] input-files

OPTIONS

input-files

*.a = library, *.o = object, *.bas = source, *.rc = win32 resource script, *.res = win32 compiled resource, *.xpm = X11 icon resource

@file

Read more command line arguments from a file

−a file

Treat file as .o/.a input file

−arch type

Set target architecture (default: 486)

−asm att|intel

Set the assembler format for Asm blocks and for code generation (x86 only)

−b file

Treat file as .bas input file

	−c		Compile only, do not link
	−C		Preserve temporary .o files

−d name[=val]

Add a global #define

	−dll		Same as −dylib
	−dylib		Create a Win32 DLL or Linux/*BSD shared library
	−e		Enable runtime error checking

−earray

Enable array bounds checking

−eassert

Enable assert() and assertwarn() checking

−edebug

Enable __FB_DEBUG__

−edebuginfo

Add debug information

−elocation

Enable full error location reporting

−enullptr

Enable null-pointer checking

−entry name

Change the entry point of the program from main()

	−ex		-e plus RESUME support
	−exx		-ex plus array bounds/null-pointer checking

−export

Export symbols for dynamic linkage

−forcelang name

Override #lang statements in source code

−fpmode fast|precise

Select floating-point math accuracy/speed

−fpu x87|sse

Set target FPU

−g

−gen gas|gcc|llvm|as64

Select code generation backend

−i path

Add an include file search path

−include file

Pre-#include a file for each input .bas

−l name

Link in a library

−lang name

Select FB dialect: fb (default), deprecated, qb, fblite

−lib

Create a static library

−m name

Set main module (default if not -c: first input .bas)

−map file

Save linking map to file

−maxerr n

Only show n errors

−mt

Use thread-safe FB runtime

−nodeflibs

Do not include the default libraries

−noerrline

Do not show source context in error messages

−nostrip

Do not strip symbol information from the output file

−o file

Set .o file name for corresponding input .bas

−O value

Optimization level (default: 0)

−p path

Add a library search path

	−pic		Generate position-independent code (non-x86 Unix shared libs)
	−pp		Write out preprocessed input file (.pp.bas) only

−prefix path

Set the compiler prefix path

−print host|target

Display host/target system name

−print x

Display output binary/library file name (if known)

−print sha-1

Display compiler’s source code commit sha-1 (if known)

−profile
