Building Git head version of "zello_sysman.cpp" fails
While latest release version (23.05.25593.9) works fine, building Git head version of zello_sysman:
g++ -O2 -Wall -o zello_sysman zello_sysman.cpp -lze_loader -locloc
Fails to following errors:

Note: as this is very useful tool for testing Sysman implementation, I'm building it against release version of L0, not against Git head version. Others can do the same, as this tool has been mentioned in different public Sysman related tickets (not in just this project).
Hi @eero-t Please ensure you have level zero headers in version that is pointed in manifest of neo repo as of commit you are building on https://github.com/intel/compute-runtime/blob/master/manifests/manifest.yml#L51
Ok, so it requires the latest L0 v1.9.9 release, released 10 days ago. I assume it should work also with newer versions?
Because this tools is of general use, also with distro versions of L0 & compute-runtime, I think it would be good to have better warning when L0 versions is too old, something like this in the code:
#if !defined(L0_HEADER_VERSION) || L0_HEADER_VERSION < 10909
# error "v1.9.9 or newer L0 headers required"
#endif
However, L0 headers seem to be missing defines that could be used for such check. I've added ticket https://github.com/oneapi-src/level-zero/issues/111 for that. Let's keep this open until that is resolved.
After such defines are provided by L0, zello_sysman could also use suitable ifdefs to build support for newer L0 features only when system L0 version (headers) support them.
This would require occasionally removing older ifdefs [1] to keep code maintainable, so it might be too much effort compared to just updating required L0_HEADER_VERSION error check.
[1] E.g. when distros upgrade their L0 versions against which zello_sysman might get compiled against.
Ok, so it requires the latest L0 v1.9.9 release, released 10 days ago. I assume it should work also with newer versions?
When checking the L0 APIs more carefully, spec version 1.5.0, added in L0 frontend v1.9, should actually suffice.
Based on that, and info from https://github.com/oneapi-src/level-zero/issues/111, adding something like this (untested):
#if ZE_API_VERSION_CURRENT < ZE_MAKE_VERSION( 1, 5 )
# error "zello_sysman.cpp requires L0 API >= v1.5"
#endif
to zello_systman.cpp would be enough to fix this ticket (no additional L0 API extension version checks are needed).
PS. Intel repos apparently have still only v1.8.x frontend version (as I was using those when I got this issue), as does Debian: https://salsa.debian.org/debian/level-zero/-/blob/master/debian/changelog
Whereas latest Fedora has already v1.9.x L0 frontend in F37 and newer: https://src.fedoraproject.org/rpms/oneapi-level-zero
