It appears there is a compatibility issue with the current version of the amd_hsmp.h header file. https://github.com/amd/amd_hsmp/blob/master/amd_hsmp.h To resolve this, could you please try replacing the existing version with an older amd_hsmp.h header file? This should allow the build process to work with the older kernels. > > > + > > +The library requires CMake (v3.5.0) to be built. > > + > > +As a reference, the following table shows a mapping between the DPDK > > +versions and the E-SMI library and kernel version supported by them: > > + > > +.. table:: DPDK and E-SMI library and kernel version compatibility > > + > > + ============== ============== ===================== > > + DPDK version E-SMI version Linux Kernel version > > + ============== ============== ===================== > > + 24.11+ 4.0.0 6.7+ > > + ============== ============== ===================== > >
