I proceeded as follows
1. apt-get install  octave3.2-headers
2. git clone https://github.com/dac922/octave-instrument-control-toolbox.git
3. cd ~/octave-instrument-control-toolbox/usbtmc_tb
4. chmod +x  build.sh
5. ./build.sh
Unfortunately an error pops up as can be seen here below:

address@hidden:/home/student/octave-instrument-control-toolbox/usbtmc_tb#
./build.sh
usbtmc_tb.cc: In function ‘octave_value_list Fusbtmc_read(const
octave_value_list&, int)’:
usbtmc_tb.cc:122: error: call of overloaded ‘append(int&)’ is ambiguous
/usr/include/octave-3.2.4/octave/oct-obj.h:119: note: candidates are:
octave_value_list& octave_value_list::append(const octave_value&)
/usr/include/octave-3.2.4/octave/oct-obj.h:121: note:
octave_value_list& octave_value_list::append(const octave_value_list&)

Any idea how to work around this?

thanks
