#850 can't support ipv6 when compile with mingw

[ir193]

hi,
apologize if i post duplicate. I'm new to sf.net

I'm using mingw32(gcc 4.3.3) and windows7sp1 to compile privoxy. have two problem:
1. got an error

jbsockets.c: In function ‘get_host_information’:
jbsockets.c:979:22: error: ‘NI_MAXSERV’ undeclared (first use in this function)
jbsockets.c:979:22: note: each undeclared identifier is reported only once for e
ach function it appears in
make: *** [jbsockets.o] Error 1

2. after edit the source:
#define NI_MAXSERV 32
i compile successfully. But it didin't support IPV6.

I wonder whether it a bug of configure or I miss some package

The missing NI_MAXSERV definition is a bug that is already worked around in CVS. Unfortunately it wasn't discovered until after the 3.0.19 release.

This should only be a problem when Privoxy is compiled on Windows without IPv6 support, though.

Are you configuring with --enable-mingw32?
Can you attach the configure output?

configure output

I think it's because getaddrinfo need _WIN32_WINNT >= 0x0501
and there is no _WIN32_WINNT defined when configure
you can work around this.

[Fabian Keil]

Strange. In the past setting WINVER seems to have been sufficient. Can you try adding _WIN32_WINNT?

Is this the workaround you were thinking of?

[ir193]

I'm really sorry. I installed a latest MSYS. The problem disappeared. It seems the older gcc cause the problem.

[Fabian Keil]

No problem. Thanks for letting us know.
