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

• 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 ?

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

• Indeed, sorry, I misunderstood your original post.

You should not have this problem then

As a workaround you can add

@\$(QTDIR)\include\QtANGLE@

• 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.

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

But something looks awry about the generated file.

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

# ------------------------------------------------------

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.

• 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.

• 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.

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

"\$(QTDIR)msvc2010\include\QtANGLE"

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?

• The OpenGL build will indeed not use ANGLE

• 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.
