Serial Port communication

So you didn't compile it. The build failed. It seems that you forgot to run qmake or something. Looks like the compiler tries to compile the unix version.

Hey i did run qmake. Hey this is what i did before i cud compile it in VS

qmake -project
qmake projectname.pro
nmake projectname.pro
qmake -tp vc projectname.pro

But no luck i keep getting this error. I even tried the pre compile version of qextserialport lib.

You shouldn't have issued "qmake -project". Go ahead and read the docs about what it does.
