Forum: GNU Radio Error while running gr-modtool

Hello everyone,

I am learning about making new blocks in GNURadio.

I'm following the tutorial
http://gnuradio.org/redmine/projects/gnuradio/wiki...

I'm getting the following output on running gr_modtool

===============================================================================================

manu@sense:coding$ ~/install/bin/gr_modtool newmod howto
Traceback (most recent call last):
  File "/home/manu/install/bin/gr_modtool", line 41, in <module>

    modtool.setup()

options.srcdir)

    return _gnuradio_core_general.gr_prefs_get_string(self, *args, 
**kwargs)
TypeError: in method 'gr_prefs_get_string', argument 4 of type 
'std::string
const'

===============================================================================================

Where am I going wrong?
I have installed using the git clone I made about a week ago.


Thanks,
