Hi all,

I try to use the log(scalar) operation in pre processing utility but I have the following error message:

~/OpenFOAM/ag74290-1.6.x/applications/utilities/preProcessing/vit_cond_init_4t_rand$ wmake
SOURCE=vit_cond_init_4t_rand.C ;  g++ -m64 -Dlinux64 -DWM_DP -Wall -Wno-strict-aliasing -Wextra -Wno-unused-parameter -Wold-style-cast -Wnon-virtual-dtor -O3  -DNoRepository -ftemplate-depth-40 -I/home/ag74290/OpenFOAM/OpenFOAM-1.6.x/src/finiteVolume/lnInclude -IlnInclude -I. -I/home/ag74290/OpenFOAM/OpenFOAM-1.6.x/src/OpenFOAM/lnInclude -I/home/ag74290/OpenFOAM/OpenFOAM-1.6.x/src/OSspecific/POSIX/lnInclude   -fPIC -c $SOURCE -o Make/linux64GccDPOpt/vit_cond_init_4t_rand.o

make: *** [Make/linux64GccDPOpt/vit_cond_init_4t_rand.o] Error 1
I can use it in simple C++ code but not in OpenFOAM 1.6.x
Any advice?

Hello Pascal,

you may try it this way:

scalar logTest = Foam::log(scalar(42));
