Qt 5.2 VS2010 - ‘GLES2/gl2.h’: No such file or directory

TEDSON

bq. fatal error C1083: Cannot open include file: ‘GLES2/gl2.h’: No such file or directory

This is the error I get after trying to use QFileDialog.

Well I got some other QFileDialog unidentified errors first, but adding...
@#include <QtGUI>
#include <QFileDialog>@
...took care of them.

But now I have the above.

The file is present in this folder...
C:\Qt\Qt5.2.0\5.2.0\msvc2010\include\QtANGLE\GLES2
Which I have in my include directorie path, as well as just...
C:\Qt\Qt5.2.0\5.2.0\msvc2010\include\QtANGLE

The error comes from qopengl.h and is line 82...
@# include <GLES2/gl2.h>@

Any ideas on my mistake, and what I should try?

Hi,

Since you are building with ANGLE, did you install the Direct X sdk ?

TEDSON

I did not, I was unaware I needed it.
Thought I only needed that if I was compiling Qt sources.

I'd appreciate any advice or links you might offer.

SGaist

Indeed, sorry, I misunderstood your original post.

You should not have this problem then

As a workaround you can add

@$(QTDIR)\include\QtANGLE@

To your pro file

TEDSON

I'll try that, thanks.

First though, I'll have to figure out how to make a .pro file because there is not one (that I can see( in my solution explorer.

Thanks for the tip, I appreciate it.

TEDSON

From the Qt5 menu in VS I selected "create basic .pro file"

But something looks awry about the generated file.

@# ----------------------------------------------------

This file is generated by the Qt Visual Studio Add-in.

------------------------------------------------------

TEMPLATE = app
TARGET = QTGUIHELLOWORLD
DESTDIR = ../Win32/Debug
QT += core widgets gui
CONFIG += debug
DEFINES += WIN64 QT_DLL QT_WIDGETS_LIB
INCLUDEPATH += ./GeneratedFiles
.
./GeneratedFiles/Debug
DEPENDPATH += .
MOC_DIR += ./GeneratedFiles/debug
OBJECTS_DIR += debug
UI_DIR += ./GeneratedFiles
RCC_DIR += ./GeneratedFiles
include(QTGUIHELLOWORLD.pri)@

Most notably, the line "DEFINES += WIN64 QT_DLL QT_WIDGETS_LIB"

I'm very new to Qt but I definitely not using a 64bit windows, however my CPU (AMD) is 64 bit.

TEDSON

If I add this to my existing .pro

INCLUDEPATH += "C:/Qt/Qt5.2.0/5.2.0/msvc2010/include/QtANGLE/GLES2/gl2.h"

Intellisense still tells me it cannot find it, and my project will not compile.

If I add #include "C:/Qt/Qt5.2.0/5.2.0/msvc2010/include/QtANGLE/GLES2/gl2.h" to any of my project files, intellisense is happy, but project still will not compile because of same errors as above.

TEDSON

New info:

If I use QFileDialog in Qt Creator, everything is just fine, and it compiles and runs.

I'm sure though that it's still using the VS 2010 compiler.

TEDSON

Does this look correct, what I've added to vc++ directories -> include directories?...

"$(QTDIR)msvc2010\include\QtANGLE"

TEDSON

I downloaded and installed
Qt 5.2.0 for Windows 32-bit (VS 2010, 570 MB) (Info)

If I get rid of that and get
Qt 5.2.0 for Windows 32-bit (VS 2010, OpenGL, 569 MB) (Info)
Instead, do you think this error will go away?

SGaist

The OpenGL build will indeed not use ANGLE

TEDSON

Thanks, I'll keep it in mind if I cannot find the solution, to whatever it is I'm doing wrong.

Not sure if you still have the problem, but I had the same issue.

Simple do not include QtGui and everything works fine!

Adding $(QTDIR)\include\QtANGLE to Project Properties->C++->General->Additional Include Directories has solved the problem for me.
