I have tried to build the correct versions of dependencies m4 and bison for installing swak4Foam but for some reason both of these show errors while executing the make command. I am using OpenFOAM version 2012 in Ubuntu 20.04. And I have m4 version 1.4.18 already installed in the system but the one required to be built is 1.4.17. And the version of bison required is 2.7.


The error encountered after the make command of m4:
gcc -I. -g -O2 -MT freadahead.o -MD -MP -MF $depbase.Tpo -c -o freadahead.o freadahead.c &&\
mv -f $depbase.Tpo $depbase.Po
