## Per-language overrides: `[build.c]`, `[build.cxx]`, `[build.asm]`, `[build.llvm_ir]`
|
||
|
||
Each language can have its own table that overrides the flat `[build]` settings:
|
||
|
||
```toml
|
||
[build]
|
||
compiler = "clang"
|
||
standard = "c11"
|
||
|
||
[build.c]
|
||
standard = "c23"
|
||
compiler = "gcc"
|
||
|
||
[build.cxx]
|
||
standard = "c++23"
|
||
compiler = "g++"
|
||
|
||
[build.asm]
|
||
compiler = "nasm"
|
||
flags = ["-felf64"]
|
||
|
||
[build.llvm_ir]
|
||
compiler = "llc"
|
||
```
|
||
|
||
The flat `[build]` acts as fallback; per-language tables take precedence for their language.
|
||
|
||
Пример:
|
||
|
||
```toml
|
||
[build]
|
||
language = ["cpp", "c"]
|
||
standard = "c17"
|
||
standard = "c23"
|
||
cxx_standard = "c++23"
|
||
compiler = "clang"
|
||
kind = "sharedlib"
|
||
cflags = ["-Wall", "-Wextra"]
|
||
pkg_config = ["sdl2", "gl"]
|
||
```
|
||
|
||
## [набор инструментов]
|
||
|
||
```toml
|
||
[toolchain]
|
||
cc = "/usr/bin/clang"
|
||
cxx = "/usr/bin/clang++"
|
||
as = "/usr/bin/as"
|
||
ar = "/usr/bin/ar"
|
||
ld = "/usr/bin/ld.lld"
|
||
uic = "/usr/bin/uic" # Qt
|
||
moc = "/usr/bin/moc" # Qt
|
||
rcc = "/usr/bin/rcc" # Qt
|
||
```
|
||
|
||
Raw config также поддерживает `uic`, `moc` и `rcc` для генерации кода Qt.
|
||
|
||
## [зависимости]
|
||
|
||
См. [dependencies](/docs/reference/dependencies).
|
||
|
||
## [запустить]
|
||
|
||
```toml
|
||
[запустить]
|
||
cmd = "./target/{profile}/{name}"
|
||
```
|
||
|
||
Подстановки:
|
||
|
||
* `{version}` — версия из [package]
|
||
* `pkg_config`
|
||
* `{profile}` — отладочная / релизная версия
|
||
* `{name}` — имя из [package]
|
||
|
||
По умолчанию `cmd` вычисляется как `./target/{profile}/{name}`.
|
||
|
||
## [рабочая область]
|
||
|
||
См. [workspaces](/docs/reference/workspaces).
|
||
|
||
## [archive]
|
||
|
||
Optional post-build step: format a FAT volume and copy built artifacts into a disk image. Runs after a successful package build (and after workspace member builds that define `[archive]`).
|
||
|
||
| Field | Required | Description |
|
||
| ------------ | -------- | ------------------------------------------------------------------------------------------- |
|
||
| `output` | yes | Image path relative to project root (`{profile}` allowed) |
|
||
| `format` | yes | `fat12`, `fat16`, or `fat32` |
|
||
| `size` | no | Image size: bytes or `K`/`KB`/`M`/`MB`/`G`/`GB` (default `1474560` ≈ 1.44 MiB) |
|
||
| `offset` | no | Byte offset of the FAT volume inside the image (default `0`) |
|
||
| `label` | no | Volume label (max 11 chars, default `VOLUME`) |
|
||
| `bootsector` | no | Path to a 512-byte boot sector written at offset 0 when `offset` is 0 (`{profile}` allowed) |
|
||
| `layout` | no | List of `{ from, to }` entries (files or globs → path inside the volume) |
|
||
|
||
```toml
|
||
[archive]
|
||
output = "target/{profile}/disk.img"
|
||
format = "fat12"
|
||
size = "1440K"
|
||
label = "MYOS"
|
||
bootsector = "target/{profile}/boot.bin"
|
||
|
||
[[archive.layout]]
|
||
from = "target/{profile}/kernel.bin"
|
||
to = "KERNEL.BIN"
|
||
|
||
[[archive.layout]]
|
||
from = "assets/*"
|
||
to = "/"
|
||
```
|
||
|
||
Typical pairing with `kind = "flat-bin"` (NASM `-f bin`) for bootloaders and pure-ASM OS images.
|
||
|
||
## `flat-bin` (kind)
|
||
|
||
Produces a raw binary (default extension `bin`) for boot sectors, kernels, and freestanding payloads.
|
||
|
||
### Assemblers
|
||
|
||
| Tool | Language / compiler | How flat-bin is produced |
|
||
| ---- | ------------------------------------------ | -------------------------------------------- |
|
||
| NASM | `language = "asm"`, `compiler = "nasm"` | `-f bin` → `\<stem>.bin` |
|
||
| FASM | `compiler = "fasm"` | direct write (use `format binary` in source) |
|
||
| GAS | `compiler = "as"` / `"gas"` | assemble → `objcopy -O binary` |
|
||
| MASM | `compiler = "ml"` / `"ml64"` | assemble → `objcopy -O binary` |
|
||
| LLC | `language = "llvm_ir"`, `compiler = "llc"` | `-filetype=obj` → `objcopy -O binary` |
|
||
|
||
```toml
|
||
[build]
|
||
language = "asm"
|
||
compiler = "nasm"
|
||
kind = "flat-bin"
|
||
extension = "bin"
|
||
roots = ["src/boot.asm"]
|
||
```
|
||
|
||
### C / C++
|
||
|
||
Compile all sources, link with `-nostdlib -static` (plus your `ldflags` / `ldscript`), then convert the intermediate ELF/PE with `objcopy -O binary` to `\<filename|name>.bin`.
|
||
|
||
```toml
|
||
[build]
|
||
language = "c"
|
||
compiler = "clang"
|
||
kind = "flat-bin"
|
||
freestanding = true
|
||
filename = "kernel"
|
||
extension = "bin"
|
||
ldscript = "linker.ld"
|
||
ldflags = ["-T", "linker.ld"]
|
||
```
|
||
|
||
Notes:
|
||
|
||
* Multi-file **ASM** packages emit one `\<stem>.bin` per source; **C/C++** emit a single project binary.
|
||
* `objcopy` tools tried in order: `llvm-objcopy`, `objcopy`, `gobjcopy`.
|
||
* Incompatible with `build.qt = true`.
|
||
* `dcr run` rejects `flat-bin` (not a host executable).
