<title>Gromacs installation on Mac OSX, again</title>
<font face="Verdana, Helvetica, Arial"><span style="font-size: 12px;">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>
