Error compiling Octave 3.4.3

[bd satish]

Hi,

Octave 3.4.3 (on Debian x86_64) fails to compile because of missing  fftw3.h.

make[3]: Entering directory `/home/debian/foss/octave-3.4.3/src'
./DLD-FUNCTIONS/config-module.sh ..

The problem is that the "-I/path/to/fftw3"   flag is not added to the
above compilation statement (as you can see) even though I specified
explicitly during 'configure' and indeed 'configure' succeeded finding
it:


./configure --prefix=$HOME/foss/installed/octave --with-pic
--with-fftw3-includedir=/home/debian/foss/installed/fftw/include
--with-fftw3-libdir=/home/debian/foss/installed/fftw/lib
--disable-shared --disable-dl --enable-static
--with-blas="-L/home/debian/foss/installed/lapack -lblas"
--with-lapack="-L/home/debian/foss/installed/lapack -llapack"


I verified that the path mentioned in "--with-fftw3-includedir" is
indeed valid and fftw3.h exists in that directory but looks like this
is not added to CXXFLAGS ( or CPPFLAGS) and hence compilation fails.
