No lines numbers shown here.

However what's the point in building and shipping the debug versions
as part of official releases when they are rather useless?

Isn't the issue that the debug symbols are not shipped in the first place?
They usually reside in the object files, or are extracted into a dsym archive, 
and neither are shipped with the binary installation.

So placing the sources at the original compiled path won't really help.

It's a known and, AFAIU, unfixable issue. That's just how the debug format 
stores the information.

I think it should show line numbers, but it can't find the source code because 
you don't have the source code at the same place as the debugging information 
expects it to be.

Not that I have tried this BUT in theory if you knew the exact paths that Digia 
used to build the Qt distribution and set up your sources in the same paths 
then the debug symbols might start working. At least that is the first thing I 
would try.

Is this a known issue or shall I create a bug report?

Seems that there is no such problem when using the debug version of a
self-compiled Qt library.

Is this an issue with the official release (5.6 beta Mac)?

Yes. Debug symbols in the pre-compiled builds do not work.

[Interest] Qt 5.6.0 beta / Mac / lldb / Debug Symbols

2016-01-14 Thread Nils Jeisecke via Interest 
Hi list,

I'm running into trouble trying to step into Qt's sources while debugging.

To select the debug version of Qt I'm using DYLD_IMAGE_SUFFIX=_debug
which according to the image names in the backtrace seems to work.

However I don't get lldb to display line numbers or show source code
for stack frames inside Qt.

I've installed Qt 5.6 for Mac OS X (clang64) beta using the official
installer, including Qt's source code.

This is an example backtrace:

(lldb) bt
* thread #1: tid = 0x5d27d2, 0x7fff93f71386
libsystem_kernel.dylib`mach_msg_trap + 10, queue =

frame #18: 0x7fff878695ad libdyld.dylib`start + 1
frame #19: 0x7fff878695ad libdyld.dylib`start + 1

Any ideas?
