## Building

different compilers you will need to install it twice. The dependencies are:

* A GCC cross-compiler for a SuperH architecture
* The [gint kernel](/Lephenixnoir/gint)

By default `sh-elf` is used to build; you can override this by setting the
`target` variable.
```sh
% make target=sh4eb-elf
```
Install as usual:
```sh
% make install
# or
% make install target=sh4eb-elf
```
If you have the older setup with two toolchains (`sh3eb-elf` and `sh4eb-elf`),

will need to make and install twice.
## Basic use
To access the library, include the `<libprof.h>` header file.
