Binaries
ELF binaries and ISO images can be downloaded on the releases page.
Dependencies
- NASM, with support for
elf32
output format - Linker capable of emulating
elf_i386
genisoimage
(from cdrkit) ormkisofs
(from cdrtools)
If the system linker does not support emulating elf_i386
, a cross-linker can
be built from GNU binutils. Use ./configure --target i386-elf
,
then set LD = i386-elf-ld
.
To use mkisofs
instead of genisoimage
, set GENISOIMAGE = mkisofs
.
Make variables can be set on the command line or in config.mk
.
Build
make
This will assemble and link a multiboot ELF file, tetrasm.elf
.
The default build is debug
, which includes debug symbols and runtime debug
functions. The release
build excludes these.
make BUILD=release
There is also a test build, which features tests of the core functions rather than the game.
make BUILD=test
ISO
make iso
This will create a bootable ISO using GRUB Legacy, tetrasm.iso
.
Emulation
make qemu BUILD=release
This will boot tetrasm.elf
in QEMU using multiboot.
If run in the debug build, waits for a debugger to attach.
make qemu-iso BUILD=release
This will boot tetrasm.iso
in QEMU.
Debugging
make gdb
This will attach GDB to QEMU started from make qemu
.
