FreeBASIC Build Options

Set the build date for the compilation. See SOURCE_DATE_EPOCH Specification. The SOURCE_DATE_EPOCH environment variable specifies a build time constant (a decimal unsigned integer in unix time format) to be used during the build process. Setting this variable sets the values to be returned by __DATE__, __TIME__, and __DATE_ISO__ built-in macros when a source is compiled. This in turn affects the values returned by __FB_BUILD_DATE__ and __FB_BUILD_DATE_ISO__ when fbc compiler itself is built.

to set -g -exx etc. for the compiler build and/or link

same for the rtlib and gfxlib2 build

install/uninstall directory, default: /usr/local

GNU triplet for cross-compiling

"32", "64" or empty for cross-compiling using a gcc multilib toolchain

fbc, gcc, ar programs (TARGET may be prefixed to CC/AR)

to see full command lines

build source tree into self-contained FB installation

use "-d ENABLE_PREFIX=$(prefix)" to hard-code the prefix into fbc

append a string like "-0.24" to fbc/FB dir names, and use "-d ENABLE_SUFFIX=$(ENABLE_SUFFIX)" (non-standalone only)

use prefix/lib64/ instead of prefix/lib/ for 64bit libs (non-standalone only)

use "-d ENABLE_STRIPALL" with all targets

disable "-d ENABLE_STRIPALL" with all targets

determine the sha-1 of the current commit in repo and store it in the compiler

explicitly indicate the sha-1 to store in the compiler

bindist: The package/archive file name without path or extension

bindist: Allows adding a custom suffix to the normal package name (and the toplevel dir in the archive)

bindist: The manifest file name without path or extension

bindist/gitdist: FB version number

bindist: Don't package readme/changelog/manpage/examples

automatically set depending on the target but can override for special builds where the build tools have different file naming than the target to build (i.e. cross compiling)

use "-d DISABLE_GAS64_DEBUG" (see below)

Tells fbc to not search for some libstdc/libc depending on target platform

Sets default x86 cpu type to one of FB_CPU_TYPE
For example make compiler DEFAULT_CPUTYPE_X86=FB_CPUTYPE_386

Sets default arm cpu type to one of FB_CPUTYPE
make compiler DEFAULT_CPUTYPE_ARM=FB_CPUTYPE_ARM7A_FP

build for a self-contained installation

assume FB's lib dir uses the given suffix (non-standalone only)

hard-code specific $(prefix) into fbc

use prefix/lib64/ instead of prefix/lib/ for 64bit libs (non-standalone only)

configure fbc to pass down '--strip-all' to linker by default

store 'some-sha-1' in the compiler for version information

disable gas64 debugging comments in asm files even if FB_DEBUG is defined (-g)

tells fbc to not search for some libstdc/libc depending on target platform

This make the compiler set default x86 cpu type to one of FB_CPUTYPE

This make the compiler set default arm cpu type to one of FB_CPUTYPE

override the library directory - default is set depending on TARGET

override object file directory - default is set depending on TARGET

override compiler object directory - default is set depending on TARGET

override the compiler flags when building fbrt library

override the linker flags then building fbrt library

build without X11 headers (disables X11 gfx driver)

build without gpm.h (disables GetMouse in the Linux terminal (TERM=linux), although the TERM=xterm variant keeps working)

build without ffi.h (disables ThreadCall)

build without OpenGL headers (disables OpenGL gfx drivers)

build without Linux framebuffer device headers (disables Linux fbdev gfx driver)

build without DirectX 10 driver (disable D2D driver in windows)

build without libtinfo or ncurses (disables console commands)

build without locale info (affects Unix only; makes no difference unless you call setlocale() manually). Does not remove setlocale(LC_CTYPE, "") call.

build without wchar_t type or functions. wstring becomes ASCII only (fbc needs to match this).
