Can I compile libh2o under windows

There is a fair amount of work involved to port it cleanly to native WIN32. I spent a few afternoons on it to get a feel for it. That said I believe it builds in Cygwin...

I try to complie libh2o using mingw. but gnulib-tool can't support cmake.I failed to import <sys/socket.h> ... to the project under windows.

I just built libh2o via CYGWIN. There is only a minor change required:

$  cmake . -G"Unix Makefiles" -DWITH_BUNDLED_SSL=0 -DWITH_MRUBY=0 -DLIBUV_LIBRARIES=~/git/libuv/.libs/libuv.a -DLIBUV_INCLUDE_DIR=~/git/libuv/include -DLIBUV_VERSION=1.11.0
$ make examples-simple

I tried building the complete server today - it worked. Now I can use h2o on Windows. I think this should be submitted in a pull request.

This thread is now more than 3 years old. h2o has changed since then and the current sources no longer build or work as-is on MingW (if they ever did). I made a patch for h2o while porting Urbit to Windows that the h2o project might be interested in. Its scope is limited to what I needed for Urbit: only the libuv variant is built, and no fastcgi or memcached support. The biggest change by line count is caused by libuv uv_buf_t and h2o h2o_iovec_t declaring the two fields in reverse order: on MingW, libuv uses the WinSock order to avoid extra copying, whereas h2o uses the POSIX order. The patch swaps the fields in h2o_iovec_t if built on MingW.

@locpyl-tidnyd This patch doesn't apply on current h2o; could you rebase on current master and submit it as a pull request?

[jwinarske]

Sure.

[locpyl-tidnyd]

That was rather more work than I expected, but here it is: #2720 It shouldn't break anything outside MingW or require extra effort maintaining it beyond using the new H2O_IOVEC_XXX macros and h2o_iovec_init(base, len) instead of (h2o_iovec_t){base, len}, but it's not battle-tested by any means. I contribute it in the hope that somebody else will find it useful.
