Qdnslookup_unix cross compilation error

edhana

Hi,

I'm trying to cross compile qt 5.3.0 from git to arm(IMX25) architecture, which I create a device configuration under mkspecs/devices, but I always get this message from the make command:

My configure command is:

Anyone knows how to fix it?

thanks in advance

I'm getting the same issue compiling for MIPS

kernel/qdnslookup_unix.cpp: In static member function 'static void QDnsLookupRunnable::query(int, const QByteArray&, const QHostAddress&, QDnsLookupReply*)':
kernel/qdnslookup_unix.cpp:165:27: error: 'struct __res_state::<anonymous union>::<anonymous>' has no member named 'nsmap'
state._u._ext.nsmap[0] = MAXNS + 1;

To get round this I made a change to:
qtsource/qtbase/src/network/kernel/qdnslookup_unix.cpp

I changed (line:152):
#if defined(Q_OS_LINUX)

To this:
#if 0

Not sure what I'm losing, but it go me building.
