[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.
