Normally you don't use gint directly, instead the fxSDK provides project
templates that are set up to use gint. Please see the
[fxSDK README file](/Lephenixnoir/fxsdk) for details.
## Building and installing manually
You will need a couple of tools:
* A suitable GCC toolchain in the `PATH`. You can absolutely *not* build gint
with your system compiler!
* The tutorial on Planète Casio builds an `sh-elf` that works everywhere
* For fx-9860G II, `sh3eb-elf` is strongly advised
* For fx-CG 50, `sh4eb-elf` (with `-m4-nofpu`) is slightly better but
`sh3eb-elf` is completely fine
* The [fxSDK](/Lephenixnoir/fxsdk) installed and available in the PATH.
gint is built using the [fxSDK](/Lephenixnoir/fxsdk), which provides a suitable
CMake environment for the calculator. gint is always installed in the
compiler's install path (as given by `sh-elf-gcc --print-search-dirs`) which is
detected automatically, so normally you don't need to set the install prefix.
fx-CG 50 developers probably want a g3a wrapper as well; the reference
implementation is Tari's [mkg3a](https://gitlab.com/taricorp/mkg3a). This is

gint is built with CMake; the fxSDK provides CMake modules to target the
calculator, as well as a couple of utilities. gint is always installed in the

## Linking with gint manually
## Using in CMake-based add-ins
Find the `Gint` module and link against `Gint::Gint`.
```cmake
find_module(Gint 2.1 REQUIRED)
target_link_libraries(<target_name> Gint::Gint)
```
## Using in Makefile-based add-ins
Projects created with the fxSDK link with gint out-of-the-box. If you're not
using the fxSDK, you will need to:
