Compilation Order and Single Precision Issues

gocarts · October 13, 2009, 10:14

I just tried compiling the latest git version of OpenFOAM 1.6.x

commit 99d4b831e6f25f3fba273a1fb517aea65e704acd
Author: henry <henry>
Date: Mon Oct 12 13:52:36 2009 +0100

from scratch on Linux and encountered a few minor problems:

1) libfvMotionSolver.so now depends on libforces.so, so during compilation src/postProcessing needs to compile prior to src/fvMotionSolver and src/engine and be reflected in src/Allwmake. Something like:

Code:

.
.
postProcessing/Allwmake
conversion/Allwmake

# Depends on postProcessing/functionsObjects/forces
wmake libso fvMotionSolver
wmake libso engine
.
.

2) Within the new solver applications/solvers/multiphase/interMixingFoam in alphaEqns.H and threePhaseInterfaceProperties/threePhaseInterfaceProperties.[H|C] there are numerous uses of max(...,0.0) whereas for successful compilation for single precision max(..., scalar(0.0)) is required

Hope this is helpful.

Thanks for the bug reports, the fixes are now in our OpenFOAM-1.6.x git repository.
