Qt4 Network Module Build Error -- Your help appreciated

murthy

Hi

I am having a bit of a problem compiling Qt Network module (c:\qt\2010.05\qt\src\network\network.pro;
target: QtNetwork4.dll) on Windows Vista Home Edition.

I have given the mkspecs using set QMAKESPEC=c:\qt\2010.05\qt\mkspecs\win32-g++

My path is set PATH=%PATH%;c:\qt\2010.05\mingw\bin

I have run qmake to generate the Makefiles.

If I add to the defines QT_NO_HTTP in network.pro, the module
is built successfully.

Please advise how to fix the following error message as I need to have
HTTP functionality in the QtNetwork4.dll

Hm... I don't have a Windows box here to test it, I think it's a good idea to ask for help abut this issue in the #qt IRC channel, freenode server.

hi murthy, have built Qt a few times and never seen an issue with networking module ...

just want to confirm -- did you run configure before the build
also is qt\bin also in your path?

I've never had such issue either. Try the latest sources (git)
