/usr/bin/ld error

[bruce.labitt at autoliv.com]

The fun never ends...

My make file compiles everything, using the compiler of choice ( using 
brute force, not using elegance ).  However, ld fails to find -lfftw3. The 
error is:

/usr/bin/ld: skipping incompatible /usr/local/lib/libfftw3.so when 
searching for -lfftw3
/usr/bin/ld: skipping incompatible /usr/local/lib/libfftw3.a when 
searching for -lfftw3
/usr/bin/ld: skipping incompatible /usr/local/lib/libfftw3.so when 
searching for -lfftw3
/usr/bin/ld: skipping incompatible /usr/local/lib/libfftw3.a when 
searching for -lfftw3
/usr/bin/ld: cannot find -lfftw3
collect2: ld returned 1 exit status
make: *** [server] Error 1

Now, having lived through this once before, I made sure that 
/etc/ld.so.conf.d contained a file called fftw.conf

$cat fftw.conf
/usr/local/lib

In the file /etc/ld.so.conf is:
include ld.so.conf.d/*.conf

ldconfig shows:

# ldconfig -v 
ldconfig: Path `/usr/local/lib' given more than once
/usr/local/lib:
        stuff
        libfftw3.so.3 -> libfftw3.so.3.2.3

In the above make file the CCOPTS= -O3 -m64 -mcpu=970 -mtune=970 
-D_FILE_OFFSET_BITS=64 -fopenmp -Wall -Wcast-qual

Previously, I have linked another project to FFTW using the same options 
as above.  So far, the only difference is that with the previous project I 
made my own script that compiled everything and linked it in one line... I 
wanted to use a make file this time around, the compile times are longer 
now...

Any suggestions?  I have not touched fftw since April.  Haven't updated 
compilers either...
