I am quite new to unix as well as GNU radio, but after practising with the
different modules and reading alot about it in papers and tutorials I've
been able to understand how to use some of its functions. Presently I am
trying to make a block in GNU Radio Companion from a C shared library file
generated from Matlab. 

I've been following the tutorial on how to create a signal processing block
and I believe my files are ready, also I have edited most of the scripts as
per requirements. However, when I try to do "make"/"sudo make" after
./bootstrap and ./configure, the compiler is unable to build because it
cannot find one of the matlab libraries that are a dependency for my .h and
.cc file. I've tried looking everywhere on forums for a solution but there
is no information regarding this. The library files in question are the
mclmcrrt.h and mclcppclass.h. Matlab used them to compile the shared library
so the path I set for them in bashrc seems correct. When I do "locate" I can
find the libraries as well.

Following error is generated and then it says that all subsequent functions
being used in the .cc file being not initialized and stops.
In file included from ./howto_square_ff.h:26,
                 from howto_square_ff.cc:32:
./libmyfunc.h:14:22: error: mclmcrrt.h: No such file or directory
./libmyfunc.h:15:25: error: mclcppclass.h: No such file or directory

I'm on Ubuntu 9.10 - the Karmic Koala release

Is there something specific that needs to be done for the "make" procedure
to read these libraries ? Any help in this regard will be highly
appreciated. This is my first time posting here, so I hope I was able to
convey as much information as possibly regarding the problem.
