Problems with IBM compiler Date: 2005/10/28 06:32 Name: Sergey Dear Dr. Ozaki, I have a problem with compiling openMX code on IBM platform using xlc compiler. I got: xlc_r -I/usr/local/include -Dnompi -c Poisson.c "Poisson.c", line 179.11: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 180.11: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 197.31: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 198.31: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 224.11: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 225.11: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 242.31: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 243.31: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 397.11: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 398.11: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 415.31: 1506-019 (S) Expecting an array or a pointer to object type. "Poisson.c", line 416.31: 1506-019 (S) Expecting an array or a pointer to object type. Using gcc compilation is OK. Do you know how to solve this problem? Thanks, Sergey

Re: Problems with IBM compiler ( No.1 ) Date: 2005/10/29 13:46 Name: T.Ozaki Hi, The error arising lines are function call lines of FFTW3. Did you compile FFTW3 using xlc instead of gcc ? xlc compiler seems to require consistency for the compileration including libraries. Regards, T.Ozaki Re: Problems with IBM compiler ( No.2 ) Date: 2005/10/30 00:37 Name: Sergey Dear T. Ozaki, FFTW3 library was compiled using xlc compiler. What should I include else? Thanks, Sergey Re: Problems with IBM compiler ( No.3 ) Date: 2005/10/31 23:44 Name: T.Ozaki Hi, Though I am not sure what happened, if possible, I would like to appreciate what happens in case of FFTW2 instead of FFTW3. Regards, T.Ozaki Re: Problems with IBM compiler ( No.4 ) Date: 2005/11/02 01:58 Name: Sergey Dear Taisuke , Fortunately, nothing happened using FFTW2 - everything is compiled without problem. But I think FFTW3 works much faster than FFTW2. Thanks, Sergey Re: Problems with IBM compiler ( No.5 ) Date: 2005/11/02 08:37 Name: T.Ozaki Hi, There is almost no difference between FFTW2 and FFTW3 in computational time, since only a simple one-dimensional FFT is called in OpenMX.
