installing gnuradio-devel with +debug option

[vamsi765]

I'm trying to install latest gnuradio developer edition with all related options

sudo port install gnuradio-devel +zeromq +ctrlport +performance_counters +debug

I run into the following error:

Error: Failed to extract gnuradio-devel: 

ERROR:
 In order to install this port as +debug,
Qt4 must also be installed with +debug.

By the way, rest of the options work:

sudo port install gnuradio-devel +zeromq +ctrlport +performance_counters

In the future, please use WikiFormatting and Cc the port maintainers (port info --maintainers gnuradio-devel).

Qt4 wants you to install it using +debug, in order to use its debug libraries with GNU Radio. This requirement seems a little over the top to me: Why not allows dependent ports to use the debug libraries if installed and not otherwise?

Can you do a test? Edit the file "$(port dir gnuradio)/../../_resources/port1.0group/qt4-1.0.tcl" (maybe with sudo), and remove the initial chunk of code:

# check for +debug variant of this port, and make sure Qt was
# installed with +debug as well; if not, error out.
platform darwin {
    pre-extract {
        if {[variant_exists debug] && \
            [variant_isset debug] && \
           ![info exists building_qt4]} {
            if {![file exists ${qt_frameworks_dir}/QtCore.framework/QtCore_debug]} {
                return -code error "\n\nERROR:\n\
In order to install this port as +debug,
Qt4 must also be installed with +debug.\n"
            }
        }
    }
}

Then try:

sudo port clean gnuradio-devel
sudo port install gnuradio-devel +debug

and see if that works.

what is the folder directory for GNURadio port? $(port dir gnuradio)

[michaelld (Michael Dickens)]

I don't know what the folder directory for the GNURadio port is. That's why I say to use $(port dir gnuradio) since it will always work.

[vamsi765]

Aah, okay. I thought you put that as place holder.
But I didn't find any file in that particular folder[the folder doesn't exist].

Sorry: port1.0group -> port1.0/group, so: $(port dir gnuradio)/../../_resources/port1.0/group/qt4-1.0.tcl

[vamsi765]

Got it. Now the port got installed.
What do you think is the right fix?

[michaelld (Michael Dickens)]

I think the right fix is to move the deleted code into the qmake 1.0 portgroup, since I think this is a QMake issue. It's not a CMake issue.

Does the installed GNU Radio +debug actually do anything useful for you -- i.e., can you use it for debugging using gdb or lldb?

[vamsi765]

The fix works. I see the instructions using lldb! Thanks!

[michaelld (Michael Dickens)]

Thanks for the feedback. I'll look into moving that script segment from qt4 to qmake. Seems like the way to go, at least on my first thinking about this.

[michaelld (Michael Dickens)]

Done.
