[gmx-users] Re: fftw & enable-float

[Bo Yang]

Hello, Lianqing:

Yes, I did. 

Here is how I did:

----

[:~/fftw/fftw-2.1.5] bo% make distclean

--

[:~/fftw/fftw-2.1.5] bo% ./configure -enable-float

checking for a BSD-compatible install...
/usr/bin/install -c
checking whether build environment is sane... yes
---
---

[:~/fftw/fftw-2.1.5] bo% ./configure
--prefix=/Users/bo/fftw/fftw-2.1.5
checking for a BSD-compatible install...
/usr/bin/install -c
checking whether build environment is sane... yes

[:~/fftw/fftw-2.1.5] bo% make install
Making install in fftw
/bin/sh ../mkinstalldirs /Users/bo/fftw/fftw-2.1.5/lib

---

Libraries have been installed in:
   /Users/bo/fftw/fftw-2.1.5/lib


-----end 'fftw'



This time, the 'fftw' seems to be installed. Then I
switch to 'Gromacs'. Here is how I did:

[:~/gromacs-3.2.1] bo% setenv CPPFLAGS
-I/Users/bo/fftw/fftw-2.1.5/include

[:~/gromacs-3.2.1] bo% setenv LDFLAGS 
-L/Users/bo/fftw/fftw-2.1.5/lib 

[:~/gromacs-3.2.1] bo% ./configure 

---
---
configure: error: Cannot find any single precision
sfftw.h or fftw.h
Do you have single precision FFTW installed? If you
are using packages,
note that you also need fftw-devel to compile GROMACS.
You can find the
software at www.fftw.org, and detailed instructions at
www.gromacs.org.

---- end of Gromacs

Thank you for any comments.

Bo
