Any help is appreciated.
Ubuntu 18.04 has MinGW-w64 5.0.4, while 6.0.0 is required (note: MinGW-w64
version is not the same as GCC version). I've certainly hit this issue with
older MinGW.
Got it, thank you! FWIW, documentation [1] doesn’t mention about the 6.0.0
requirement
[1] https://doc.dpdk.org/guides/windows_gsg/build_dpdk.html
While we're at this, we should also update this with the minimum
required version of the Clang compiler.
