I am trying to compile swak4Foam with OpenFOAM 2.3.0. I am using bison in version 3.0.2 and I set the environmental variable for new bison in the command line. gcc is 4.8.2. I am using the mercurial swak4Foam and I switch to 2.0.x branch as the wiki page suggests.
The output from Allwmake is attached. It seems that at some stage certain files are not found. Please advise.
OK. Have a look at the output. There it says:
Bison is version 3.0.2
swak4Foam only confirmed to work with Bison 2.x
Maybe this should be a bit stronger: swak4Foam does not compile with Bison 3.x
I had a look and it seems that the changes required to make the grammar work with 3.x will break 2.x and as the majority of the systems still has 2.x I decided to stay with this for the time being.
May I ask which Linux-distro you are using (because it seems that it also uses Python3 as the default python)
Until there is time to make swak work with bison 3.x: let the Allwmake-script fail with incompatible bison-versions. Add the possibility to add a "private" bison compiled from sources (for users where bison is provided by the system)
Thanks. I am using Arch Linux. They are very progressive which sometimes gets in the way. I should have checked it first - it seems I still have the capability to downgrade to bison 2.7. I'll give it a try but providing separate bison together with swak sounds like a great idea.
Just pushed the possibility for a private bison installation to the mercurial repository. If the version of bion doesn't fit the requirements a message how to install it is advertised.
For the time being I'll stick with bison 2.x. 3.x doesn't seem to have that big benefits and most Linux-distros that are used for "work" still have 2.x
