I would like to use my own FFTW in OpenFOAM-v2206. Following the instructions in etc/config.sh/FFTW:


# For central installations not located under ThirdParty:
# 1. use fftw-system
# 2. and provide full path for FFTW_ARCH_PATH



I set


fftw_version=fftw-system
export FFTW_ARCH_PATH=<full path to my intallation>


where


> ls $FFTW_ARCH_PATH
cmake libfftw3f.la libfftw3f.so.3.6.10 libfftw3.so.3
libfftw3.a libfftw3f.so libfftw3.la libfftw3.so.3.6.10
libfftw3f.a libfftw3f.so.3 libfftw3.so pkgconfig


Yet when I build, the fft is not found (and so some components are skipped).


What have I missed?

Not sure.

Do you observe linking with the FFTW libraries that you provide during the build?

Does "nm -g <executable-name>" provide valuable information?

In the log file:


Using none/system (skip ThirdParty build of FFTW)


and later:


==> skip randomProcesses library (no FFTW)


As an aside, I have built OpenFOAM with my Boost (and GMP and MPFR):


# Use my Boost...

CGAL=$WM_PROJECT_DIR/etc/config.sh/CGAL
cp -ip $CGAL $CGAL.0
sed -i "s/^\(boost_version\)=.*$/\1=boost-system/" $CGAL
sed -i "s|^\(export BOOST_ARCH_PATH\)=.*$|\1=$PROJECT/opt/gnu/lib/$BOOST|" $CGAL

# ...Use my GMP and MPFR

sed -i "s|^# \(export GMP_ARCH_PATH\)=.*$|\1=$PROJECT/lib/gmp-6.2.1|" $CGAL
sed -i "s|^# \(export MPFR_ARCH_PATH\)=.*$|\1=$PROJECT/lib/mpfr-4.1.0|" $CGAL

and this worked---CGAL was successfully built. In simpler terms, I only had to set BOOST_ARCH_PATH, GMP_ARCH_PATH, and MPFR_ARCH_PATH appropriately; yet the same does not appear to work for the FFTW.

Default SOLVED/possible dependency error

Evidently there may be a dependency error in the build, for I found that while Vandermonde.o was compiled, the link for libvandermonde.so did not find this object. Somehow this resulted in the build not executing $WM_PROJECT_DIR/wmake/scripts/have_fftw and consequently neither FFTW_INC_DIR nor FFTW_LIB_DIR were set, with outcome (for example)


==> skip randomProcesses library (no FFTW)


By simply running Allwmake again (in the same environment), everything was built, moreover the FFTW I had specified via $WM_PROJECT_DIR/etc/config.sh/FFTW by FFTW_ARCH_PATH was used:


ldd librandomProcesses.so | grep fftw
libfftw3.so.3 => /home/maxd/GNU/opt/gnu/lib/fftw-3.3.10_gcc-12.1.0/lib/libfftw3.so.3 (0x00007fd63bb67000)


Is such a dependency error deserving of a bug report?
