[libfabric-users] CXI libraries present but can not be compiled

[Marc Caubet Serrabou]

Hi,

I already opened a ticked to ofiwg at lists.openfabrics.org, but I also try 
here in the user list, in case that somebody found a similar issue and 
has an answer to it.

I am trying to compile libfabrics 1.22.0 with CXI provider support. 
Despite the expected CXI provider header files are present, as well as 
the CXI library, I get the following errors:

configure: WARNING: The EFA provider requires rdma-core v31 or newer.

The libraries are the following and come from Cray, and are in the 
standard directories (/usr for include files, /usr/lib64 for libraries)

🔥 
[caubet_m at login001:~/git/buildblocks/Libraries/libfabric(ofi_1.22.0)]# 
rpm -qf /usr/include/uapi/misc/cxi.h /usr/include/cxi_prov_hw.h 
/usr/lib64/libcxi.so

cray-libcxi-0.9-SSHOT2.1.3_20240529150829_3d1dc9246116.x86_64

The configure options are the simplest ones, which should enforce CXI only:

/var/tmp/caubet_m/libfabric-1.22.0/src/configure 
--prefix=/opt/psi/Libraries/libfabric/1.22.0/ --enable-cxi

What am I missing, and how shall I proceed? Is the compilation expecting 
a different set (or version) of CXI libraries?

Thanks a lot,

Marc
