# Soft-FP sh3eb port of OpenLibm
|
|
|
|
This is a fork of [OpenLibm](https://github.com/JuliaMath/openlibm) with
|
|
support for the sh3eb architecture, intended for add-in programming on fx-9860G
|
|
and fx-CG 50.
|
|
|
|
## Building
|
|
|
|
You will need a GCC toolchain built with `--target=sh3eb-elf`, such as the
|
|
`sh-elf-gcc` commonly used on Planète Casio.
|
|
|
|
First locate the compiler's install directory. This is normally the
|
|
`lib/gcc/sh3eb-elf/<version>/` folder inside the install path of the compiler.
|
|
|
|
```
|
|
% PREFIX=$(sh-elf-gcc --print-search-dirs | grep install | sed 's/install: //')
|
|
```
|
|
|
|
You can then build and install the static `libopenlibm.a` archive and the headers.
|
|
|
|
```
|
|
% make USEGCC=1 TOOLPREFIX=sh-elf- libdir="$PREFIX" includedir="$PREFIX/include" install-static install-headers
|
|
```
|
|
|
|
## Using in a program
|
|
|
|
Simply link with `-lopenlibm` as you would do with `-lm`.
