"Unable to read symbols" Problem

I am using QT4.7.0 (with QtCreator) on OSX 10.6.5.

I am getting the following errors when I debug:

Unable to read symbols for QtSql.framework/Versions/4/QtSql (file not found).
Unable to read symbols from "QtSql" (not yet mapped into memory).
Unable to read symbols for QtGui.framework/Versions/4/QtGui (file not found).
Unable to read symbols from "QtGui" (not yet mapped into memory).
Unable to read symbols for QtNetwork.framework/Versions/4/QtNetwork (file not found).
Unable to read symbols from "QtNetwork" (not yet mapped into memory).
Unable to read symbols for QtCore.framework/Versions/4/QtCore (file not found).
Unable to read symbols from "QtCore" (not yet mapped into memory).

I have checked and these files are found in the /Library/Frameworks directory. I edited the /etc/paths directory and now my path looks like this:


echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/trey/Bin:/Library/Frameworks:/usr/X11/bin

So the PATH looks like it is pointing to the directory; what am I missing here? Is there another variable I need to modify?

This is a raw install of QtCreator right from their site, add a single button to a form and then compile and debug. Is there a document that shows any extra steps for the mac?

The directory looks like this:

Bounce?

This happens when I run the file that was compiled under 'Debug' someone has to know what is going on.

Not being a Mac OS X user I cannot offer a concrete answer.

If the problem only appears when you compile your application in debug mode then I would hazard a guess and say that the debug libraries are not installed or not being found. The SDK on Windows installs a set of release mode Qt libraries to operate Qt Creator and a completely separate set of release and debug Qt libraries that are used to develop against. Does this happen on OS X? If so, which set is in /Library/Frameworks and where might the other ones be?

One of the things that I don't understand is that the error is "Unable to read symbols for QtSql.framework/Versions/4/QtSql (file not found)." The file is found here "/Library/Frameworks/QtSql.framework/Versions/4/QtSql". So how does Qt Know to use the "/Library/Frameworks" directory as a prefix? I tried setting up the path, but that did not fix it. I also tried to add this line to the .pro file, but that did not fix it either. "LIBS += /Library/Frameworks".

If I do a listing of that directory I get the following:

ll /Library/Frameworks/QtSql.framework/Versions/4
total 3216
drwxrwxr-x 61 root admin 2074 Dec 20 15:07 Headers
-rw-rw-r-- 1 root admin 591088 Sep 10 12:19 QtSql
-rw-rw-r-- 1 root admin 1049632 Sep 10 11:54 QtSql_debug

So you can see the file is there and a debug file is also found.

Did you ever solve this? I'm having the exact same problem

Was this ever solved? I have similar issue: When I run through debugger I get:
Debugging starts
Unable to read symbols for QtWebKit.framework/Versions/4/QtWebKit (file not found).
Unable to read symbols from "QtWebKit" (not yet mapped into memory).
Unable to read symbols for QtGui.framework/Versions/4/QtGui (file not found).
Unable to read symbols from "QtGui" (not yet mapped into memory).
Unable to read symbols for QtCore.framework/Versions/4/QtCore (file not found).
Unable to read symbols from "QtCore" (not yet mapped into memory).

Thanks!

The debugger cannot read debugging symbols from the libraries because they are not built with debugging symbols; probably because they are release libraries.

Thanks Guru for your reply. I am new to QT and Mac. The libraries are at /Library/Frameworks ... The project was actually built in Windows and I am testing if it works on Mac. Do you have any solution/fix for this?

rebuild the libs with debug symbols included.

Thanks Amleto!

As I mentioned before, I'm a newbie ... How can I "rebuild the libs with debug symbols included"? I've already completely rebuilt the project ...

rebuild Qt libs, not your project. The missing symbols are in qt binaries, not your application. There are tutorials online.
