error: #error qmetatype.h must be included before any header file that defines Bool

[akosmaroy]

Hi,

I'm trying to compile the code on ubuntu 14.10 with Qt 5.4 using Ninja, and I get the following:

                 from ../examples/cpp/common/qt/QtUtils.h:22,
                 from ../examples/cpp/common/Common.h:159,
                 from ../examples/cpp/common/opengl/Textures.cpp:20:
/home/akos/src/oculus/usr/Qt/5.4/gcc_64/include/QtCore/qmetatype.h:53:2: error: #error qmetatype.h must be included before any header file that defines Bool
 #error qmetatype.h must be included before any header file that defines Bool

and then a bunch of similar errors. I wonder what I'm doing wrong :(

I haven't tested on anything other than windows for a while. I'll do a
pass on making sure the OSX and Linux builds are unbroken this week.

thanks for looking. I had to make additional changes to make it compile on Linux (Ubuntu 14.10), please see my git diff pasted here (let me know if you need it in another form):

[akosmaroy]

after compiling with the above differences, I can run examples 2.1 and 2.2 fine (the tracker is found), but none of the examples that would want to display something work :( I wonder how one should debug this.

the 'official' oculus config app & the sample inside the config app work fine.

[akosmaroy]

an additional thing that is needed for compilation on Linux is to:

#define __stdcall

I'm not sure where to put this. I've put this into Config.h, but that seems to get re-generated

[jherico]

You can put it into Common.h or Platform.h. Common.h actually has most of
the platform specific defines. Platform.h is really just a header of
utility functions that mask a bunch of platform specific functionality.

.

[jherico]

I've applied most of the changes, or at least variations on them to get the build compiling on my Linux system. See the other issue you opened for status. Please re-open if this doesn't resolve the issues for you.

[akosmaroy]

I'd like to re-open this one (I'm not finding a way on how). after #58 is solved, I'm testing this on the jherico fork. I'm getting the same error as before, using Qt 5.4:

and then a zillion more errors

[jherico]

I've reproduced this on 12.04. It seems Qt is pretty finicky about other library headers. Initial attempts at reordering the headers hasn't produced great results yet, but I'm still investigating.

[jherico]

I've made some changes (in my fork) to get the compilation working on Linux. The library seems to compile fine now, although the shadertoy example (the only thing actually using Qt at the moment) is still failing to compile. I'll keep working on it to try to determine the problem.
