I download libxml2 2.9.4 in here, when i ./configure; make
, i get following error:
nanohttp.c: In function ‘xmlNanoHTTPConnectHost’: nanohttp.c:1073:18: error: storage size of ‘hints’ isn’t known struct addrinfo hints, *res, *result; ^ nanohttp.c:1079:11: warning: implicit declaration of function ‘getaddrinfo’ [-Wimplicit-function-declaration] status = getaddrinfo (host, NULL, &hints, &result); ^ nanohttp.c:1079:2: warning: nested extern declaration of ‘getaddrinfo’ [-Wnested-externs] status = getaddrinfo (host, NULL, &hints, &result); ^ nanohttp.c:1085:35: error: dereferencing pointer to incomplete type ‘struct addrinfo’ for (res = result; res; res = res->ai_next) { ^ nanohttp.c:1089:7: warning: implicit declaration of function ‘freeaddrinfo’ [-Wimplicit-function-declaration] freeaddrinfo (result); ^ nanohttp.c:1089:7: warning: nested extern declaration of ‘freeaddrinfo’ [-Wnested-externs] nanohttp.c:1073:18: warning: unused variable ‘hints’ [-Wunused-variable] struct addrinfo hints, *res, *result; ^

Answer
I find the solution:
in nanohttp.c, the error line:
#if defined(HAVE_GETADDRINFO) && (defined(SUPPORT_IP6) || defined(_WIN32)) { int status; struct addrinfo hints, *res, *result;
so i can disable ipv6 to don’t compile this block code. I try following code will work:
./configure --enable-ipv6=no LIBS="-lpthread"; make
I find “–enable-ipv6” in “libxml2-src/configure”
