# AGB ABI Library (agbabi)
## Quick Start Guide
Link with `libagbabi.a` via the normal means for your build environment (eg: `-Lagbabi` for GCC and Clang), and add the `include` directory via the normal means for your build environment (eg: `-Iagbabi/include`).
Linking will implicitly activate the `armeabi` library.
Include the `armeabi.h` and `agbabi.h` headers to access the `armeabi` and `agbabi` C functions.
```c
#include
#include
#include /* POSIX context switching */
int main() {
unsigned int a = __aeabi_uidiv(9u, 3u);
int b = __agbabi_sqrt(25u);
ucontext_t c;
getcontext(&c);
return 0;
}
```
## API Reference
- [Arm Standard Compiler Helper Function Library (aeabi)](docs/aeabi.md)
- [AGB Support Library (agbabi)](docs/agbabi.md)
- [POSIX Support Library](docs/posix.md)
## Building
Requires `gcc-arm-none-eabi` cross compiler, and either `cmake` or `meson` for configuration.
### CMake 3.18+
To cross-build `libagbabi.a` in directory `build/`:
```shell
cmake -S . -B build --toolchain=cross/agb.cmake
cmake --build build
```
### Meson 0.56.2+
To cross-build `libagbabi.a` in directory `build/`:
```shell
meson setup build --cross-file=cross/agb.ini
meson compile -C build
```
