Hi, I'm running into some issues linking against libraries. I'm running a
"console-image" Angstrom on the Beagleboad and I've been adding packages as
necessary to support compiling code directly on the board.
To support building packages on the BB, I bitbaked "package-native-sdk" and
"pkg-config" and installed those packages with all the other dependencies as
indicated by opkg: gcc, libgcc, automake, perl, .... etc.
Now I'm trying to compile a program natively that links against fftw3 library
so I bitbaked and installed the fftw3 library: the libfftw3, fftw3, and
fftw3-dev. Now to link to fftw3 I added the "-L /usr/lib -lfftw3" flags for
link but i would get the error message
cannot find -lfftw3
collect2: ld returned 1 exit status
I also tried using "pkg-config --libs fftw3" in my Makefile and I still get the
same error message. I don't know why GCC can't seem to find the library
especially that pkg-config and ldconfig have links to the library. The
following are outputs from pkg-config and ldconfig
ldconfig -v | grep fftw
libfftw3.so.3 -> libfftw3.so.3.2.2
libfftw3f.so.3 -> libfftw3f.so.3.2.2
pkg-config --list-all
fftw3f FFTW - fast Fourier transform library
fftw FFTW - fast Fourier transform library
fftw3 FFTW - fast Fourier transform library
it seems to me that everything is in order but i'm probably missing something
... any help would be greatly appreciated. thanks
