How to build qt out of source

Question

I was searching a lot through Qt forums and Google for the last few days, but I could not find any obvious answer to this question.

I found the -prefix opti

Answer 1

I moved the shadow build out of my home folder to a folder in C: and it worked. I know it's weird, but that's what happened. I suspect it must be a bug in syncqt.

Answer 2

At least the problem with the missing include files (e.g. qscriptengine.h) may by solved by temporary adding \qt\4.5.2-sources\include\Qt to the include path.

Answer 3

IIRC on Windows, you have to do a sandbox install, you can't do the UNIX-typical "make install".

There are two options usually for building Qt, -prefix-install and -prefix /foo

You pick one, so if -prefix doesn't allow you to type make install, then I guess on Windows you have to use the -prefix-install route, which is a sandboxed install to the directory you extract Qt to.

I'm guessing you didn't try make install? So try that. It should install Qt to a separate directory away from the sources.

Answer 4

Basically, you just have to run configure.exe from your build directory. For example:

mkdir \qt\4.5.2-build
cd \qt\4.5.2-build
set PATH=%cd%\bin;%PATH%
\qt\4.5.2-sources\configure.exe -platform win32-msvc2005

Where sources are in \qt\4.5.2-sources, that would cause the build to go into \qt\4.5.2-build on the current drive.

Also, you must have perl in your PATH, ActiveState Perl is suggested.

I had not previously heard of this limitation where the build and source directories must be at the same level. If you hit this problem you could try working around it by creating a symbolic link (see mklink command).
