<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>I read with interest a recent (11/11) posting regarding an error message seen when installing Gromacs 3.2.1 on Mac OSX:<BR>
<BR>
“checking for sfftw.h... no<BR>
checking for fftw.h... no<BR>
configure: error: Cannot find any single precision sfftw.h or fftw.h<BR>
Do you have single precision FFTW installed?...(remainder of longer error message)”<BR>
<BR>
I am getting the same message. I have installed FFTW 3.0.1 using the —enable-float flag, and since I am setting it up in a different location, I have also set the CPPFLAGS and LDFLAGS to point at the new location. There’s a couple of interesting things that I have observed. First, if I go to the directory where I installed FFTW, I find the files “fftw3.f” and “fftw3.h” from the FFTW installation. Since the file names did not appear to be what Gromacs was seeking, I simply copied the “fftw3.h” file into two renamed files “sfftw.h” and “fftw.h”. When the configure command is entered, the error message changes slightly:<BR>
<BR>
“checking for sfftw.h... yes<BR>
checking for fftw.h... yes<BR>
configure: error: Cannot find any single precision sfftw.h or fftw.h<BR>
Do you have single precision FFTW installed?...( remainder of longer error message)”<BR>
<BR>
Thus, the flags appear to be working since the configuration sees the file names in the proper location, but it looks like the required files are not being recognized. I am trying to install on Mac Powerbook G4, OS 10.3.6, using the Apple developer tools that are bundled with the software.<BR>
<BR>
Full disclosure: I am by no means a Unix expert, thus, I am hoping that the pros on the list will recognize something simple that I have overlooked.<BR>
<BR>
Thanks for any help.<BR>
