[gmx-users] Gromacs Installation Error on Powerbook G$ Running OS 10.5.8

[Matthew Bick]

Dear Gromacs community.  I am attempting to install the latest version
of Gromcs (4.5.4) on my Mac Powerbook G4 (1.67 MHz, OS 10.5.8).  I
have successfully installed FFTW following the instructions provided
on the Gromacs installation page.

"./configure --with-fft=fftw3" appears to work properly, but when I
perform  "Make" I get the following errors:

ld: symbol(s) not found
collect2: ld returned 1 exit status
make[4]: *** [libgmx.la] Error 1
make[3]: *** [all-recursive] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all] Error 2
make: *** [all-recursive] Error 1

I did configure my shell (bash) environment, as per the Gromacs
installation instructions.  "Make" runs for about 10 minutes before I
get these errors.  I have searched the mailing list, and have seen
people report problems similar to mine, but couldn't determine how
those problems were resolved.  Also from the mailing list, I
understand that the errors I've listed above aren't that informative.
If it helps, I repeatedly get the following warnings during "Make":

../../../../include/types/../thread_mpi/atomic/gcc_intrinsics.h: In
function ‘tMPI_Atomic_add_return’:
../../../../include/types/../thread_mpi/atomic/gcc_intrinsics.h:46:
warning: implicit declaration of function ‘__sync_add_and_fetch’
../../../../include/types/../thread_mpi/atomic/gcc_intrinsics.h: In

function ‘tMPI_Atomic_cas’:
../../../../include/types/../thread_mpi/atomic/gcc_intrinsics.h:57:

‘__sync_bool_compare_and_swap’

If anyone has any suggestions, they would be greatly appreciated.
Thanks.
