Hi all,

I'm trying to compile a simple c++ code with mkoctfile and I am getting some linkage problems

[Peter-Williamss-Computer:~/sources/octave] pjw% mkoctfile runsum.cpp
ld: can't locate file for: -ldfftw

Anyone seen this problem??

Here are the details of my setup

[Peter-Williamss-Computer:~/sources/octave] pjw% gcc -v
Reading specs from /usr/libexec/gcc/darwin/ppc/3.1/specs
Thread model: posix
Apple Computer, Inc. GCC version 1175, based on gcc version 3.1 20020420 (prerelease)

octave version 2.1.46 (unmodified binary fink install)

from mkoctfile

${FFTW_LIBS="-L/sw/lib -ldfftw"}

listing of /sw/lib/ directory

[Peter-Williamss-Computer:~/sources/octave] pjw% ls /sw/lib/libdfftw*
/sw/lib/libdfftw.2.0.5.dylib /sw/lib/libdfftw_threads.2.0.5.dylib /sw/lib/libdfftw.2.dylib /sw/lib/libdfftw_threads.2.dylib

Thanks for any advice you may have to offer,

Pete Williams
