Hi,
I came across a strange problem when building parallel amber connected to
building fftw-2.1.5. When I configure via:
./configure -mpi intel (openmpi 1.5.1 installed and MPI_HOME defined)
the script succeeds on all counts. Following make clean in both src/ dirs
and make install in the Amber/src dir, the compilation dies, amusingly
with a fork bomb 'Resource temporarily unavailable' error. The infinite
recursion of forks is caused by the libtool script in
AmberTools/src/fftw-2.1.5/ which defines a variable ECHO and calls it
$echo later on in l.449. Renaming the variable to $ECHO fixes the problem
and Amber compiles.
Since libtool is built automatically and the error appears novel, this
must be some strange system-dependent setting, where the automatic
configure script fails. My machine is pretty standard in most respects
(Fedora11, ifort/icc 11.1, recent amber checkout), so I wonder if Im the
first to see this behaviour?
fftw2 config log is attached...
Kind Regards,
Thomas
