Subject: Fw: Re: FFTW configure problem
Hi Miguel,
I went through the dialog between Miguel and Rhywek. Even i am in the same problem. I use gcc for C. I am on
Suse Linux 9.2 and tried all your options
./configure --enable-float --enable-prefix --with-gcc (I have tried with and without these options)
gmake clean && gmake all gmake install
I can find the files fftw.h rfftw.h sfftw.h srfftw.h in /usr/include. the library is in /usr/lib When i run a very small code:
#include<stdio.h>
#include<stdlib.h>
#include<sfftw.h>
int main()
{
int i, N;
fftw_complex in[]= {(1,1),(1,2),(1,1),(0,0)};
fftw_complex out[10];
fftw_plan plan;
printf("\n Enter array size\n");
scanf("%d",&N);
plan = fftw_create_plan(N,FFTW_FORWARD,FFTW_ESTIMATE);
fftw_one(plan,in,out);
fftw_destroy_plan(plan);
printf("DFT of input sequence is: \n");
for(i=0; i<4; i++){
printf("%f, %f\n",out[i]);}
return 0;
}
the errors are displayed below:
/tmp/ccgo2kIq.o(.text+0x5b): In function `main': /root/Desktop/test_fft.c:15: undefined reference
to `fftw_create_plan'
/tmp/ccgo2kIq.o(.text+0x70):/root/Desktop/test_fft.c:16:
undefined reference to `fftw_one'
/tmp/ccgo2kIq.o(.text+0x79):/root/Desktop/test_fft.c:17:
undefined reference to `fftw_destroy_plan'
collect2: ld returned 1 exit status
What would be the problem? If I have to re install
the library then do I need to use gmake distclean or anything
else?
Please suggest!
Naveen
