<![CDATA[Compile error libxml2 with mingw]]>Hello,

I'm doing compile the open source library libxml2.
I have two different version of mingw.
But I compiled libxml2 with just one.

first. GCC 4.4.0 -> libxml2 installation OK

$ export CC=/c/QtSDK/mingw/bin/mingw32-gcc
$ export CXX=/c/QtSDK/mingw/bin/mingw32-g++
$ export PATH="/c/QtSDK/mingw/bin:$PATH"
$ export PATH="/c/program files (x86)/CMake/Bin:$PATH"
$ ./Configure --without-iconv --without-python --build=i686-pc-mingw32 --prefix=/c/libxml2
$ make
$ make install

second. GCC 5.3.0 -> libxml2 make error... OTL ...

$ export CC=/c/Qt/Qt5.7.0/Tools/mingw530_32/bin/gcc
$ export CXX=/c/Qt/Qt5.7.0/Tools/mingw530_32/bin/g++
$ export PATH="/c/Qt/Qt5.7.0/Tools/mingw530_32/bin:$PATH"
$ export PATH="/c/program files (x86)/CMake/Bin:$PATH"
$ ./Configure --without-iconv --without-python --build=i686-pc-mingw32 --prefix=/c/libxml2 --host=i686-pc-winnt
$ make

This is not a Qt problem.

The only relation to Qt is that you happen to use the MinGW compiler installed with Qt libraries. However, MinGW is not part of Qt either. It is from a separate open source project.

The problem is obviously that a routine closesocket is referenced (even the line is given in your post) but not found as a compiled module. As with any source you need to find out where it belongs to and why it is not compiled or part of a library you are using.
