[solved] Glib libgpod mac os x Compile error

[KioR]

I am trying to include libgpod in my application so I can communicate with Ipods. I have compiled and installed libgpod-0.8.0 , then I got error that it requires Glib.

I installed Glib using brew install glib. However now when I try and compile it throws up error:

/usr/local/Cellar/glib/2.38.2/include/glib-2.0/glib/gtypes.h:34: error: 'glibconfig.h' file not found
#include <glibconfig.h>

Only thing I could find was that i need to include pkg-config --cflags glib-2.0 when compiling . Not sure how to do this though or if that is the problem?

In my pro file I have added :

@INCLUDEPATH += /usr/local/include/gpod-1.0/gpod
INCLUDEPATH += pkg-config --cflags glib-2.0
INCLUDEPATH += /usr/local/Cellar/glib/2.38.2/include/glib-2.0

LIBS += /usr/local/Cellar/glib/2.38.2/lib/libglib-2.0.dylib
LIBS += pkg-config --libs glib-2.0
@

my code in mainwindow is :

@Itdb_iTunesDB *db;@

I am running mac os x 10.9.1 and Qt Creator 2.8.1
Based on Qt 5.1.1 (Clang 3.1, 64 bit)

I have also tried comiling glib from source without homebrew , but same issue. It has been 3 days now I have been searching for a solution and cannot find anything on it.

Thanks

Hi and welcome to devnet,

You're not using pkg-config correctly with qmake
Try this
@
CONFIG += link_pkgconfig
PKGCONFIG += glib-2.0
@

Just to be sure, do you have pkg-config installed ?

[KioR]

Just tried adding the above into my .pro file and now get the follwing error:

:-1: error: Package glib-2.0 not found

Yes pkg-config is already installed using hombrew.

[SGaist]

then run

@pkg-config --list-all | grep glib@

To see whether it knows about any glib installed

[KioR]

from terminal I have ran pkg-config --listall which has glib-2.0 , so seems like qt is not seeing pkg-config?

[KioR]

Output of pkg-config --list-all | grep glib:

gio-unix-2.0 GIO unix specific APIs - unix specific headers for glib I/O library
taglib_c TagLib C Bindings - Audio meta-data library (C bindings)
gio-2.0 GIO - glib I/O library
glib-2.0 GLib - C Utility Library
taglib TagLib - Audio meta-data library

[SGaist]

So it's likely a path problem. What you can do is close Qt Creator, and call

@open your_project.pro@

from the command line, that should start Qt Creator with the additional paths setup you might have for your command line. If it doesn't work, remove the your_project.pro.user file after having closed Qt Creator, and call open again

[KioR]

Still the same issue. It cannot even parse the .pro file now. Below is my .pro file:

@QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = tesrre
TEMPLATE = app

SOURCES += main.cpp
mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui

CONFIG += link_pkgconfig
PKGCONFIG += glib-2.0

INCLUDEPATH += /usr/local/include/gpod-1.0/gpod
INCLUDEPATH += /usr/local/Cellar/glib/2.38.2/include/glib-2.0

LIBS += /usr/local/Cellar/glib/2.38.2/lib/libglib-2.0.dylib
LIBS +=/usr/local/lib/libgpod.4.dylib@

Tired adding PKG_CONFIG_PATH+=/usr/local/Cellar/pkg-config/0.28/bin
into qmake additional arguments, and also added a new variable under system environment but did not change anything.

[SGaist]

What do you mean by "It cannot even parse the pro file" ?
glib-2.0 should be handled by pkg-config so no need for any other setup.

@LIBS += -L /usr/local/lib -lgpod@

Is more likely for gpod

[KioR]

I mean that I cannot click the green build and run icon, as it says it cannot parse .pro file.

gpod was fine before the way i had added it and if i comment out :

@CONFIG += link_pkgconfig
PKGCONFIG += glib-2.0@

then it parses fine. But I have commented out the gpod bit for now just to make sure, and still the same.

All I have added to the .pro file now is:

@CONFIG += link_pkgconfig
PKGCONFIG += glib-2.0@

If I open in qt creator 3. then it still has the parse issue , but says:

Project ERROR: Package glib-2.0 not found

[SGaist]

Do you have several Qt Creator installed ?

[KioR]

Yeah I suppose. I have Qt5.1.1
Qt5.2.0 folders both in my user folder. Not sure why I have two, Should I try and remove one?

Qt5.1.1 has Qt creator 2.8

Qt5.2.0 has Qt creator 3.0.0

[SGaist]

Then you have your Qt 5.1.1 Qt Creator starting and this one can't handle 5.2.

Try calling open with -b /Path/to/Your/5.2/Qt Creator.app

[KioR]

I tried

open tesrre.pro -b /Users/tom/Qt5.2.0/QtCreator.app

And get:

LSGetApplicationForInfo() failed with error -10814 while trying to determine the application with bundle identifier /Users/tom/Qt5.2.0/QtCreator.app.

[SGaist]

Sorry, my bad, it's -a

[KioR]

I have uninstalled all versions of Qt , and reinstalled from the latest 5.2.1

Created a new application and tried again. Now it is asking me for glib2-development package.

Cannot find this on homebrew and no where to compile from source. So have just installed Macports and now installed glib2-devel. seems like it just installed the same files that were already present with the homebrew port, with some documentation.

Still not working and error saying:

Project ERROR: glib-2.0 development package not found

[SGaist]

You might need to add /opt/local/lib/pkgconfig to your PKG_CONFIG_PATH

[KioR]

I think the PKG_CONFIG_PATH is fine as it is now seeing glib-2.0 , but is now asking for development package.

After installing with macports doing pkg config --list-all shows the same as before , so think the development package has not installed.
Not really sure what I am supposed to see after installing it.
Do you know a better way of installing?

[SGaist]

Do you have something like

@export PKG_CONFIG_PATH=/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH@

in your .profile file ?

[KioR]

Yeah just added something similar to my .profile . It contains the following:

export PATH=/usr/local/bin:$PATH
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

Still the same. Tried launching from terminal again.

Funny, I have tried on a ubuntu install and it just works. Was amazed at how easy it was.
