[solved] Glib libgpod mac os x Compile error

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.

SGaist

Did you source the file before testing ? Otherwise the changes won't take effect

KioR

No , I did not know about that. Just tried but the same.

Just found the follwing page, which has helped a bit:

"sing-pkg-config-with-qt-creator-qmake-on-mac-osx":http://stackoverflow.com/questions/16972066/using-pkg-config-with-qt-creator-qmake-on-mac-osx

Basically I have added the following to my .pro file:

@QT_CONFIG -= no-pkg-config@

So now I have :

@QT_CONFIG -= no-pkg-config
CONFIG += link_pkgconfig
PKGCONFIG += libgpod-1.0 taglib@

This however will only work if I launch the project from within terminal.
There are suggestions of fixes for Qt Creator , but none of them seem to work.

SGaist

I personally always start Qt Creator from the command line to ensure that it will have the environment set by .profile

KioR

Yeah , I will just live with it like this for now. Thanks for the prompt help SGaist.

Now to get the libs working in windows. That should be fun.

You might be interested by "this":http://stackoverflow.com/a/4567308 and "this":http://stackoverflow.com/a/7502061

KioR

Thanks for the above. I done the following:

sudo nano /etc/launchd.conf

added:
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

then:
grep -E "^setenv" /etc/launchd.conf | xargs -t -L 1 launchctl

Now when I launch Qt creator from dock , it find the libs fine.

Thanks , again.
