How to fix this error with ws2tcpip.h is not compaitable with winsock.h Include winsock2.h instead
If I take away ws2tcpip.h, it will end up issue at netbase.cpp where its use parameter of ws2tcpip.h , anyone can help resolve this

Trying to build max coin window qt, but have this issue.

You should use one of the latest mingw-builds toolchains. See step 1.1 to get a working environment.

Can someone please help me with this issue, I don't know what I did before to fix it but I just installed win7 in a vm to give it a try on windows7 instead of windows 8 and I am back at to the following error. I have tried installing MinGW over I know someone said install msys over mingw but I have no clue what they are talking about as haven't clarrified t hemself when asked what they meant, so any help would be greatly appreciated. I have also checked my path variables and everything seems to be correct.

Compile leveldb in msys shell and ensure genleveldb commands are commented out in your project file before qmaking and making the project.
