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).

Answer 1

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.

Answer 2

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.
