These steps (adapted from [0]) might be of help for you to build a
mini-OS application using the NEC sysml repo [1]:

1) You would need to build the legacy toolchain [2] basically only for
newlib and lwip:

<toolchain-clone> $ MINIOS_ROOT=<path_to_minios> make all

This will generate a subdirectory called <arch>-root/<arch>-xen-elf
(e.g. x86_64-root/x86_64-xen-elf) which will contain the libraries.


2) When using sysml mini-os repo, building applications is a bit
different. The applications are maintained in a different repo [3] which
you would have to clone. You will have there 3 apps and a template. On
'noxs' branch you will also have the daytime application that's in
mini-OS upstream. If for example you're choosing the 'idle' application
you should run the following commands:

<miniapps-clone> $ cd idle
<miniapps-clone> $ make XEN_ROOT=... \
       MINIOS_ROOT=<minios-sysml-clone> \
       NEWLIB_ROOT=<toolchain-clone>/x86_64-root/x86_64-xen-elf \
       LWIP_ROOT=<toolchain-clone>/x86_64-root/x86_64-xen-elf

For XEN_ROOT I believe it should work with any version >= 4.8.
