+Jeffrey, Manasi We will get the most traction from the Windows developer community if we use msvc. The only thing preventing that last time was GNU extensions used in DPDK source which were not ISO C standards compliant. We were also experimenting with Clang/LLVM running natively on Windows host but ran into a bunch of issues (maybe others made further progress?). GCC using Windows Subsystem for Linux (WSL) would be an interesting option and could be a secondary option for MSVC for Windows developers.

Much better than Cygwin type stuff. -----Original Message----- From: Thomas Monjalon <[email protected]> Sent: Wednesday, January 2, 2019 2:45 PM To: Jason Messer <[email protected]>; Harini Ramakrishnan <[email protected]>; Omar Cardona <[email protected]>; Ranjit Menon <[email protected]> Cc: Mattias Rönnblom <[email protected]>; Jeff Shaw <[email protected]>; [email protected]; [email protected] Subject: Compiler for Windows Hi, We need to gather inputs about the pros/cons of the C compilers available for Windows. Interesting criterias could be: - ease of use - availability - standards compliance - performance When the comparison will be complete, we should publish it in the doc/ directory, while porting DPDK to Windows. I start with few data: * gcc|clang on cygwin - not native * gcc/mingw * gcc/mingw-w64 * clang/mingw-w64 * clang --target=x86_64-windows-msvc * icc - not freely available * msvc - native - specific command line - not C99
