File does not exist - dependent error. Issue in building the open source application QCAD

Question

I am on Windows 10 - 64 bits.

Goal:

I am trying to build this Open Source application QCAD and following there Instructions in Compiling QCAD from Sources. Following "Windows" section, I have done this:

Installed MS SDK and .Net framework 4
Installed QT Unified Windows x86 2.0.1-1 with the MSVC2013 and MSVC2015 compilers

Problem:

Once I build in QT Creator as MSVC2013->Debug->Mainwindow, I get 8 duplicated errors:

D:\VisualStudio2015\VC\include\stdint.h:17: error: C2371: 'int8_t': redefinition; different basic types

If I search for int8_t I find bunch of its usage and couple of its definitions:

One in spatialindex\capi\sidx_config.h:

#if _MSC_VER <= 1500
typedef __int8 int8_t;
 //..
typedef unsigned __int8 uint8_t;
 //..
#endif

One in spatialindex\tools\tools.h

#if (defined _WIN32 || defined _WIN64 || defined WIN32 || defined WIN64) && !defined __GNUC__ && _MSC_VER!=1800 && _MSC_VER!=1600
typedef __int8 int8_t;
//..
typedef unsigned __int8 uint8_t;
// ..

Now if I comment out both statements in the second definition (In tools.h) I get some warnings and an error:

dependent '............\Q-CAD\src\3rdparty\qt-labs-qtscriptgenerator-5.5.0\generated_cpp\com_trolltech_qt_core\qtscript_Global.cpp' does not exist.

Attempts:

If I do what this guy did (He asks about the same error within the post), the dependent error persists.
I don't want to change any definitions like the answer in visual studio 2008 error C2371: 'int8_t' : redefinition; different basic types (http_parser.h).

Can you help me accomplish this?

EDIT:

"Now if I comment out both statements in the second definition" I just commented these couple lines in Tools.h: (No accidents occurred and if I un-comment them I get the previous error).

Who did the `#include `? You or the project? Users should not redefine Standard symbols & should update old projects to remove them. As you can edit the headers, commenting out its redefinitions is probably the best you can do unless/until you get a fixed version. ... **or** maybe this project expects you to compile with pre-C++11 settings to avoid the Standardised `int_t` types. About "if I comment out both statements in the second definition (In tools.h) I get some warning[s] and an error", that doesn't make sense, so probably you accidentally commented out an `#endif` or something — underscore_d, Aug 17 '16 at 15:12
@underscore_d Not me. I did not do anything in the code except the comment part. And regarding the comment part, see edited please. — Khalil Khalaf, Aug 17 '16 at 15:20

From the supported platforms, it only mentions msvc2010 and msvc2013; you are trying to build using msvc2015 which is not supported. Try to change the compiler and see if it works.

Good catch. I forgot to mention that I get the same error on both buildings `MSVC2013` and `MSVC2015`. I installed it just for QT Creator to configure it and for me to be able to upgrade easily later. But I am using MSVC2013 to build. – Khalil Khalaf Aug 17 '16 at 16:01
@FirstStep You did build your Qt using MSVC2013 too, right? – Kuba hasn't forgotten Monica Aug 17 '16 at 18:18
@KubaOber Correct. When I started the project, I configured as both MSVC2013 and MSVC2015 (select all) – Khalil Khalaf Aug 17 '16 at 18:42

If you built your own Qt, then there's no such thing as "select all". You'll have one installation/build of Qt for each compiler version. – Kuba hasn't forgotten Monica Aug 17 '16 at 19:11
@KubaOber see my answer. I do **not** know why it did "_not work_" first, now I do **not** know why "_it works_" :D – Khalil Khalaf Aug 18 '16 at 13:20

For some reason, when I un-checked the "Shadow Build" in Projects Settings of QT Creator on all: Debug, Profile and Release; and I ReBuilt All, It worked like a charm.

It took some time to ReBuild though.

Short version: QCAD's build configuration is broken. – Kuba hasn't forgotten Monica Aug 18 '16 at 15:37
I just tried checking back the _Shadow Build_ and ReBuild, it still works. I have no idea what is going on or what went wrong.. – Khalil Khalaf Aug 18 '16 at 15:39
It works because now your source folder is polluted with junk from the previous build. Of course it will work, but if you ever reinstall the source it'll stop working again. – Kuba hasn't forgotten Monica Aug 18 '16 at 15:41
But should not ReBuild be _cleaning_ junk before Building? and btw, when you first download the source and open it with QT Creator, yes you can "select all" compilers that you have (which I did select all (both) for MSVC 2013 and 15) and configure all files. @KubaOber – Khalil Khalaf Aug 18 '16 at 15:42
It'll clean junk in your build folder. Which is now a shadow folder, not the source folder. – Kuba hasn't forgotten Monica Aug 18 '16 at 15:43
To know that it works you must have an absolutely pristine QCAD source folder, and an empty build folder. It'll fail the same way it did before. – Kuba hasn't forgotten Monica Aug 18 '16 at 15:43
@KubaOber could you please take a look at this http://www.qcad.org/rsforum/viewtopic.php?f=33&t=4358&p=15834#p15834 Maybe you have some ideas? Thanks in advance – Khalil Khalaf Aug 19 '16 at 13:15
