Alright I have slogged through a lot of compile issue so far but there is one I can't figure out.

The build dies with the following

I'm compiling in 64 bit mode on Gentoo 2007.0 with gcc-4.1.2 , flex-2.5.33-r2 , and m4-1.4.8 if thats relevant

I found the problem. My version of flex doesn't like "]]" in the .L files . I needed to change all occurrences to "] ]" (just add a space in between them) and it worked fine. I needed to do this for several .L files.

Thanks for reporting what solved your problem!

[lakeat]

I put a space between "]]", but the results is still the same

And it doesn't work.

I suggest installing the sunrise overlay using layman and then emerge openfoam, it works, just be mindful of the openfoam env settings, it overwrites your clags, so only source the openfoam bashrc when using openfoam.

Thank you, Dewald.
I am determined to give up ubuntu, and turn back to OpenSUSE.
However, "warning: use of old-style cast" is still there. How to fix it?

Daniel

[dewaldpietersegmailcom]

Honestly I don't know, the answer for that will have to come from more knowledgeable in terms of the code, however what version of gcc do you have? With openfoam I would suggest usign the latest available in the ~amd64 tree. Gentoo "unstable" is a bit of a misnomer, my complete system runs ~amd64.
I am running gcc 4.2.3.

Daniel,
Warnings don't prevent your compilation from proceeding. It's just the Errors that you have to worry about.

I believe this particular warning came about with the transition from gcc 4.1.x to 4.2.x. I guess they were cleaning up the code and some old methods were altered such that it produces a warning. I'm not sure on this, however. Likely a google search of the warning text will give you a more satisfactory answer.

Regards,
Mike J.

Yup, the rest of the compilation is well though the warning during compiling src/trisurface *.L files is quite annoying.

And I will move on.

Here's another problem I found in running liftDrag. Has anyone tried it already?
