# vxOpenLibM
|
||||
|
||||
This is a fork of OpenLibm with the support of the sh3eb architecture, intended
|
||||
for the Vhex kernel project.
|
||||
|
||||
This work will directly patch the current openlibm sources code and use a
|
||||
custom build system based on CMake instead of the Makefile mess used in the
|
||||
original project.
|
||||
|
||||
## Installing
|
||||
|
||||
You can use the `scripts/install.sh --help` to see manual installation of the
|
||||
project. But, since the compiler used for this repository is "sh-elf-vhex"
|
||||
which automatically install this project as a own dependency you theorically do
|
||||
not need to install this project.
|
||||
|
||||
## README and Licensing
|
||||
|
||||
See the original
|
||||
[REAME file](https://github.com/JuliaMath/openlibm/blob/master/README.md) of
|
||||
the openlibm project for futher information.
|
||||
Note that Openlibm contains code covered by various licenses, see

|

* - a definition, and the corresponding external symbol, for FE_DFL_ENV
