/MyFolder/../../../boost_1_42_0/boost/gil/extension/io/jpeg_io.hpp:29: In file included from ../../../boost_1_42_0/boost/gil/extension/io/jpeg_io.hpp:29, /MyFolder/../../../boost_1_42_0/boost/gil/extension/io/jpeg_dynamic_io.hpp:31: from ../../../boost_1_42_0/boost/gil/extension/io/jpeg_dynamic_io.hpp:31, /MyFolder/main.cpp:19: from main.cpp:19: /MyFolder/../../../jpeg-8a/jpeglib.h:25: error: jconfig.h: No such file or directory

 

 

 

 

 

Cause

 

IDE: Qt Creator 1.3.1

Project type: Qt4 Console Application

Selected required modules: QtCore

Compiler: G++ 4.4.1

Boost version: 1.42.0

Additional libraries: jpeg-8a from the Independent JPEG Group

 

The following code caused the error:

 

---

#include <boost/gil/extension/io/jpeg_dynamic_io.hpp>

 

The following project file was used:

 

---

#------------------------------------------------- # # Project created by QtCreator 2010-05-02T08:31:54 # #------------------------------------------------- QT -= gui TARGET = MyProjectName CONFIG += console CONFIG -= app_bundle INCLUDEPATH += ../../../boost_1_42_0 ../../../jpeg-8a TEMPLATE = app SOURCES += main.cpp

 

 

 

 

 

Solution

 

You need to build the the jpeg-8a library, as this will create the file jconfig.h. Go to the jpeg-8a library folder and read the install.txt file.

 

When using Ubuntu 10.04, the following commands worked for me:

---

./configure make make test sudo make install

 

You will probably need to add the following line to your project file:

 

---

LIBS += -L/usr/local/lib -ljpeg

 

 

 

 

 

Failed attempts

 

 

 

 

 

Remove the jpeg-8a library

 

Remove the jpeg-8a library from the INCLUDEPATH.

 

Then, you might then get the jpeglib.h: No such file or directory compile error.
