I did a small test to check clang vs clang-cl, the compiled binary and the PDB file from the Clang-cl seems working fine in WinDbg. The problem we have that the meson.build files are not compatible with clang-cl, and the meson build command is failing. This is the first error: config\x86\meson.build:23:1: ERROR: Problem encountered: SSE4.2 instruction set is required for DPDK. Please set the machine type to "nehalem" or "corei7" or higher value /Adham
