Building Qt 5.2.1 in latest Visual Studios
-
Qt is being built based on Makefiles (which are being normally read and executed by make on Unix and nmake on Windows). When you run "configure", it will do the following for you:
- bootstrap Qt tools (namely: create qmake binary, which is then used to generate Makefiles, create moc and friends)
- generate main Makefile
- generate a separate Makefile for every module
So. Standard Qt compilation instructions (the ones you have inked) instruct you to just run "nmake". This will run the main Makefile, which in turn runs all module Makefiles.
But you are not forced to do it: if you simply cd into any module and run nmake there, only that single module will be compiled.
All resulting libraries and binaries are always put into qtbase.
Having said all this, I still think that if you are a "mid-range" end user, you should not be concerned about all this: just grab the precompiled Qt installer, or compile the whole package without getting into advanced and custom configuration. You will probably waste much more time trying to compile Qt in your specific way (we are already talking for the whole day), especially on Windows where things tend to break every time Microsoft decides to bless us all with an update to their compiler.
Now, getting to that error. It seems to be coming from precompiled headers. I don't remember the dev consensus exactly, but it might be that headers are precompiled in the .zip package. I am no expert here, but they may not be compatible with MSVC 2k13 (MS has a habit of breaking the compatibility on a regular basis). In that case, you may have more luck checking out from git (but that will take a long time + pull the Perl dependency).

Ah, I didn't need to change dir to qtbase, there is no Makefile there. Actually it's in the <path/to/qt5>.
-
Configure done. Now jom is running. Coffee, movie...
-
I'd agree with the installer approach if I was the only end-user. We're supporting software across platforms, so need the flexibility to build it how we want across platforms.
I'm not sure how long the build runs (2 cores, 1 hour?), or if JOM is actually helping at all. At least it's building. We'll see...
-
Actually, the build was finishing just as I wrote that...
-
So... ~50 minutes, give or take. JOM helped a little? More cores, maybe a non factor. Not sure if I set the CL to /MP, now that I think about it. I'm sure it could be helped.
-
Okay, now what? I've got some includes to include, and some cmakes in CD to make?
Actually I see a bunch of promising output in qtbase/lib to go with the includes.
-
... So really we "just" need the includes and the output from the prefix PWD/qtbase? The harder part is establishing a strategy for maintenance, end-user consumption, etc.
-
Okay, I reconfigured, no prefix, "qtbase/lib" dropped "in place" alongside "qtbase/include". I set the CL environment variable and ran JOM; and the build that took nearly 1 hour before, took maybe 2 minutes (conservatively)! That's on an 8-core machine. I can hardly believe that. It sure does look like the DLLs and all are there. WOW,
-
If I could mark it as an answer I would. Thanks again for setting me straight.

Well, you don't need to build Qt for your end-users. For them, you just deploy the libraries you need ("link":http://qt-project.org/doc/qt-5/windows-deployment.html, there are guides like that for every platform). But of course, you know your situation better than I do.

That depends on what you want to achieve. If you want to use Qt Creator for development, then you just need to point it to your newly built qmake.exe, and it will configure itself automatically; no need to link or include anything by hand.
If you want to use Visual Studio - there is a plugin for that available on the downloads page.
If you want to run everything from command line, you need to add qtbase/bin to PATH.
[quote]So really we “just” need the includes and the output from the prefix PWD/qtbase?[/quote]
qtbase/bin, qtbase/includes, qtbase/mkspecs. You can automatically separate those if you perform an out of source build, like this:
@
// assuming Qt source code is in qt-src
mkdir qt-build
cd qt-build
..\qt-src\configure <your Qt flags> -prefix CD\qtbase
nmake
nmake install
@This will compile and install Qt to qt-build, leaving your Qt source code intact.
-
Right I understand re: developers and deployed binaries. The configure make system is a little foreign to me is all, and when I have used it a bit opaque if cumbersome. I'm sure not once you get used to it.
Anyhow, I expect there's some way to identify libs (and dlls or .sos) for linkage on the other side of their includes. Much of which is IDE specific.
The much harder part about our situation is mitigating cross platform risk factors, less technical and more geo-political in nature, coordinating the builds.
Thanks...
-
Yeah, cross-platform build servers are always problematic. Qt makes the compilation part quite easy (the same code works on all platforms without any changes), but there always are lots of other problems to solve ;)
OK, I hope I've helped you at least a bit. If there are more questions, please ask. Have fun! :)

I can build QT using VC++ 2013 without OpenSSL, but with OpenSSL I get the errors below.
Suggestions?

Research C4430? Possibly a language standard thing? I don't know the configure option(s), but could C++11 (or other) be specified?

I configured openssl like this:
perl Configure VC-WIN32 --prefix=c:\Qt\openssl-1.0.1f\openssl-1.0.1f\release
Qt5 like this:
configure -opensource -opengl desktop -nomake tests -openssl -I C:\qt\openssl-1.0.1f\openssl-1.0.1f\include
Also tried with C++11:
configure.exe -platform win32-msvc2012 -c++11 -opensource -openssl -I C:\qt\openssl-1.0.1f\openssl-1.0.1f\include
The error message points to this line of code:
SSL* createSsl();I can't see anything wrong with that. Error message below.
Ideas?

This was a forum about building Qt. Not openssl. Can I suggest start fresh so as not to confuse readers?
