Hi Biswas,
This seems that rtftr is not able to locate the octave shared libraries. You can see this by executing "ldd ./rtftr" which will show a list of libraries to which rtftr is dynamically linked to. You will see that alongside the listing for "liboctave.so", it will say that the library was not found. So you can try the following:

1. As you said that you followed the "UBUNTU 9.04 INSTALLATION INSTRUCTIONS", I assume that you have "octave-3.0.3" is installed at "/usr/lib/octave-3.0.3/". Could you please verify this by looking for octave shared libraries using
"ls /usr/lib/octave-3.0.3/lib*". If you octave library installation was successful, this should show a "liboctave.so" entry.

2. Could you verify that the "rtftr/configure" file in you rtftr source has the following entry in Line 934

# Added by TLM - June 26,2009
CPPFLAGS="`pkg-config --cflags gtk+-2.0` -I/usr/local/include -I/usr/include -I/usr/local/include/boost-1_37 -I/usr/include/octave-3.0.3 -I/usr/include/libxml2"
LDFLAGS="`pkg-config --libs gtk+-2.0` -L/usr/local/lib -L/usr/lib -L/usr/lib/octave-3.0.3"
CXXFLAGS="-O2 -g0 -fopenmp"


If you don't find these lines, download the configure file from http://rtftr.svn.sourceforge.net/viewvc/rtftr/trunk/rtftr/configure?revision=204
I hope this helps.

Best wishes

Abhishek

I use Lenny (Debian 5.0.4) and I followed the "UBUNTU 9.04 INSTALLATION INSTRUCTIONS" in the INSTALL file.
I got an error while executing the instruction 8.b  :

./rtftr: error while loading shared libraries: liboctave.so: cannot open shared object file: No such file or directory

I can't figure out why I am getting this.
