Everything else compiles fine. This is what I get:

I’ve reinstalled fftw-2.1.5 and the dev. It’s late and I can’t make my eyes stop from blurring. I’m obviously missing an include or something. *yawn* Let me know if anything jumps out as a solution. Thanks.

Where do you have your fftw includes and libs, are they in /usr/local or ?

I use the YaST installer. /usr/local/include
Plus, I can change it using “ccmake .” and manually changing it.  I just don’t understand which path isn’t being included where.

Did you test if there is libfftw.a under /usr/local/lib ?
I had similar errors with dependencies, it could be
for example that you have libfftw2.a or somthing
in wich case you would just put a simlink to it.
(this is shoot in the dark)

Okay, now this is starting to piss me off. WTF?

I’m narrowing the problem down to fftw(2.1.5) not being properly configured somewhere. There are so many f***ing configuration files in Linux that you never know what the f***ing problem is. :( It’s looking more and more like crappy linking to demo_smoke.

I’m using here fftw-2.1.5-r3 and btw. fftw doesn’t have any configuration files, my smoke app gives me the folowing deps:

It looks like problem of fftw, it’s acting as if it didn’t get -lfftw -L/usr/local/lib (can’t find it’s own lib calls) and that’s rather
strange because cmake files works perfectly here, and I’m on a bleeding edge testing machine (everything .. well almost anyway,
is coming out from cvs,svn and git repositories)
Another shoot in the darkness, can you verify if your demos/smoke/CmakeFiles/smoke.dir/build.make contain
-lfftw -lrfftw (in my config its on line 208) and paste that line here ?

cd /usr/src/multitouch/demos/smoke && /usr/bin/c++ -fPIC $(smoke_OBJECTS) $(smoke_EXTERNAL_OBJECTS) -o smoke -rdynamic -L/usr/src/multitouch/src -L/usr/src/multitouch/tinyxml -L/usr/local/lib -Wl,-Bstatic -ltouchlib -ltinyxml -Wl,-Bdynamic -lGLU -lGL -lSM -lICE -lX11 -lXext -lglut -lXmu -lXi -lcv -lcxcore -lcvaux -lhighgui -Wl,-Bstatic -lfftw -lrfftw -Wl,-Bdynamic -Wl,-rpath,/usr/src/multitouch/src:/usr/src/multitouch/tinyxml:/usr/local/lib

That’s it for line 208 of build.make of the demo_smoke app. After various type of wiping and reinstalling I am left with this:

Okay, so using YaST doesn’t do crap. Nothing gets placed in /usr/local/lib at all even though it says it’s installed it.  Making fftw manually doesn’t do anything except the error listed in the previous post above.  Manual or automatic doesn’t work. WTF am I left with? I did a search for ‘libfftw.a’ and got nothing.

I see that suse has 2 fftw packages, are you sure you didn’t install just fftw3?
anyway here I attached my version of libdfftw.a compiled with gcc (GCC) 4.2.2
on a 32 system (version of fftw is 2.1.5-r3) I hope it works out.

libdfftw.a

I’m not such a noob that I installed fftw3 by accident. 

*** No rule to make target `/usr/local/lib/libfftw.a’, needed by `demos/smoke/smoke’.

This is all I get.

Sorry, didn’t want to offend you, It happened to me, many times to overlook something. Anyway if you take a look you can see that
naming is different (I guess It’s an suse issue), while on my machine library is called libdfftw.a at yours it’s called libfftw.a (without D).
Aside that after googlin around I found following: http://www.novell.com/products/linuxpackages/opensuse102/fftw-devel.html
which includes /usr/lib/libdfftw.a so I would try to symlink it to libfftw.a and see If that helps. I guess the problem lies in following:
#define USE_FFTWF or #define USE_FFTWD (Use double precision FFTW if found) .. (build environment of suse which seems that has flaws)
This is one of the biggest reason that I’m using gentoo .. every binary distro has similar issues (dependencies, naming conventions etc)

Fixing the symbolic links worked. Just a distro thing like usual. *yawn*
