Err, we decided to pin to 0.47.1 as it is the documented minimal supported version. https://nam06.safelinks.protection.outlook.com/?url=http%3A%2F%2Finbox.dpdk.org%2Fdev%2F20200108110251.20916-1-david.marchand%40redhat.com%2F&data=02%7C01%7CNarcisa.Vasile%40microsoft.com%7C3a156299509a4e20c63108d7aa7e5cf0%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637165332017516796&sdata=361djaQtaBeKN%2B9Fjg5IjuQ2dhfjCg0eMlHBVZA3aqw%3D&reserved=0 So the CI is stuck to the 0.47.1 version, not 0.52. Do you need something from a newer meson for Windows support? That would have to be documented. My bad, can't tell why I decided that 0.52 was pinned. I verified building with Meson 0.47.1, both cross and native, and it works well. Apologies to Narcisa for misguidance. No worries, I also cross-compiled using both 0.47.1 and 0.52.0. I was able to generate the helloworld executable and ran it successfully. Thanks! I did have to apply your patch "eal/windows: refine public interface" before applying the "MinGW-w64 support" patch set, to avoid the errors caused by including "Windows.h" in rte_os.h. So, I guess this patch needs to come first and then the patchset for mingw can be applied.
