Re: [dpdk-dev] [EXTERNAL] [PATCH 0/6] MinGW-w64 support

[Narcisa Ana Maria Vasile <Narcisa.Vasile@microsoft.com>]

Hi Dmitry, 

Thanks for the patches! I was able to compile and run natively, after applying the Meson patch that you mentioned.

I'm having some trouble with cross-compilation:

python3 meson.py -Dexamples=helloworld ../../dpdk/build ../../dpdk --cross-file ../../dpdk/meson_mingw.txt
The Meson build system
Version: 0.53.1
Source dir: /mnt/d/dpdk
Build dir: /mnt/d/dpdk/build
Build type: cross build
Program cat found: YES (/bin/cat)
Project name: DPDK
Project version: 20.02.0-rc1
C compiler for the build machine: cc (gcc 7.4.0 "cc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0")
C linker for the build machine: cc GNU ld.bfd 2.30

meson.build:4:0: ERROR: Unable to determine dynamic linker

Any ideas on how to fix this issue?

Thanks,
Narcisa Vasile

Subject: [EXTERNAL] [dpdk-dev] [PATCH 0/6] MinGW-w64 support

This patch series add support for building DPDK using MinGW-w64.

MinGW-w64 provides GNU toolchain and independent platform SDK on Windows. It also supports cross-compilation to Windows from POSIX systems by providing cross tollchains and libraries [0]. It does NOT emulate a full POSIX environment, like Cygwin or MSYS do.

There are advantages in using MinGW-w64 in addition to Clang:

1. Cross-compilation out-of-the-box. MinGW-w64 is provides a pthread
   implementation, GNU getopt, and Windows platform SDK.

2. Easier porting of POSIX applications using DPDK to Windows, because
   application code can use the same benefits as mentioned above.

3. Having both primary compilers enabled on Windows provides more
   diagnostics and generally prevents non-portable code.
