I applied your v2 patch and I did a native build on windows 10. Hit an error showing ../lib/librte_eal/windows/eal/eal_lcore.c:54:2: error: 'for' loop initial declarations are only allowed in C99 mode for (unsigned int socket = 0; socket < ^ ../lib/librte_eal/windows/eal/eal_lcore.c:54:2: note: use option -std=c99 or -std=gnu99 to compile your code Then I fixed them by having separate declaration out side for loop. then $ ninja -C build works However the output looks weird: C:\dpdk\build\examples>dpdk-helloworld.exe EAL: Detected 2 lcore(s) EAL: Detected 1 NUMA nodes hehello fllo frorom cm core 1 ore 0 Regards, William --- more detailed --- C:\dpdk>meson -v 0.53.999 C:\dpdk>gcc -v Reading specs from c:/mingw-w64/bin/../lib64/gcc/x86_64-w64-mingw32/4.8.3/specs COLLECT_GCC=gcc C:\dpdk>meson --reconfigure -Dexamples=helloworld build The Meson build system Version: 0.53.999 Source dir: C:\dpdk Build dir: C:\dpdk\build Build type: native build Program cat found: NO Program more found: YES (C:\WINDOWS\system32\more.COM) Project name: DPDK Project version: 20.02.0-rc2 C compiler for the host machine: cc (gcc 4.8.3 "cc (GCC) 4.8.3") C linker for the host machine: cc GNU ld.bfd 2.24 Host machine cpu family: x86_64 Host machine cpu: x86_64 Program cat found: NO Program more found: YES (C:\WINDOWS\system32\more.COM) Program ../buildtools/symlink-drivers-solibs.sh found: YES (sh C:\dpdk\config\../buildtools/symlink-drivers-so libs.sh) Checking for size of "void *" : 8 Library m found: YES Library numa found: NO Found pkg-config: C:\mingw-w64\bin\pkg-config.EXE (0.25)
