Hi,

Using gcc-4.4, there's a compilation error with the following errors:

triSurface/surfaceFeatures/surfaceFeatures.C:770: error: conflicting declaration 'Foam::octreeDataPoint samples'
triSurface/surfaceFeatures/surfaceFeatures.C:769: error: 'samples' has a previous declaration as 'Foam::treeBoundBox samples'
triSurface/surfaceFeatures/surfaceFeatures.C: In member function 'Foam::Map<int> Foam::surfaceFeatures::nearestSamples(const
Foam::labelList&, const Foam::pointField&, const Foam::scalarField&, const Foam::scalarField&, Foam::scalar) const':
triSurface/surfaceFeatures/surfaceFeatures.C:871: error: conflicting declaration 'Foam::octreeDataPoint samples'
triSurface/surfaceFeatures/surfaceFeatures.C:870: error: 'samples' has a previous declaration as 'Foam::treeBoundBox samples'

Any clue what's going on and the possible remedy?

I found the problem.

Basically, the compiler picks the wrong treeBoundBox's constructor.

The triSurface/surfaceFeatures/surfaceFeatures.C calls a 1-parameter constructor treeBoundBox(UList<...>). However, due to some reason, gcc-4.4 resolves this to the inlined treeBoundBox(boundBox) -- also a 1-parameter constructor.

My quick-n-dirty solution is to dynamic cast the PointField samples into its ancestor (UList). That is, from

octree<octreeDataPoint> ppTree (
    treeBoundBox(samples),
    ...
);

to

octree<octreeDataPoint> ppTree (
    treeBoundBox(dynamic_cast<const UList<point>&>(samples)),
    ...
);

Hello everybody,
I just want to say that the 'dirty work around' suggested by Verdi helped me to compile OpenFOAM-1.5-dev on a newly installed Fedora 11.
Due to the fact that it comes with gcc 4.4.0 I ended up with the same problem, but of course with the same solution.
One extra problem was that I had to add

#include "stdint.h"

in /home/dragos/OpenFOAM/OpenFOAM-1.5-dev/src/OSspecific/Unix/signals/sigFpe.C because the type uint64_t was undefined, which in turn generated a compiler error.

I hope this is helpful,
Dragos

Hi, I was able to get OF-1.6 compiled on Ubuntu and gcc-4.4 using your solution. I was able to find out meshTools had some problem but your post really helped fixing the issue. Thanks .

I have both problems mentioned above with OF 1.5.x on Fedora 11,gcc 4.4.1. I suggest the developers check those and commit it if it is necessary.

On gentoo linux with gcc-4.4.1 you will need also to include

#include <stdio.h>

into chemkinLexer.L, ansysToFoam.L and gambitToFoam.L for OpenFOAM-1.6

You will find the complete patch at: http://sources.gentoo.org/viewcvs.py...ch?view=markup

On Ubuntu 9.10 with OpenFOAM-1.5-dev svn 1562 I managed to compile using the system compile (4.4.x) after making two changes proposed above.

Namely,

  #include "stdint.h"

in /home/dragos/OpenFOAM/OpenFOAM-1.5-dev/src/OSspecific/Unix/signals/sigFpe.C because the type uint64_t was undefined, which in turn generated a compiler error.

and, in meshTools, replacing the two occurances of

Hi guys and girls

I have just replied to this thread and the comments by wyldckat:

http://www.cfd-online.com/Forums/ope...tml#post242123

He guides us here and I see that b_k has got openfoam 1.6 installed and working on Ubuntu..although, what version isn't mentioned. I am on Ubuntu Karmic!

Can someone give some help with this ....PLEASE!

i have also started this thread at the Ubuntu Forum explaining what I have done so far:

Thanks a bunch folks!

Greetings bookie56,

Well, by what I remember you'll be needing posts number 2, 3 and 6.
I used (K)Ubuntu 9.04 32 and 64 bit. Haven't tried in Ubuntu 9.10, but there is a thread (this one) that is giving some support on how to build OpenFOAM 1.6.x in Ubuntu 9.04 and 9.10 (32 ad 64bit).

I would suggest that you follow that thread and use Mads script, because the other choice I see for you is taking a step back to Ubuntu 9.04 and use the pre-built binaries of OpenFOAM

In case you still want to be with the recent Ubuntu and older OpenFOAM, and can't figure out how to implement post 2,3 and 6, than I suggest you follow the chapter 5 (here), only points 1 and 2, of the wiki page I posted a while back (for cross-compiling OpenFOAM in Linux for Windows). Than you should be able to follow the user manual. Those patches shouldn't disable the capability of building the Linux version of OpenFOAM.

Best regards,
Bruno

Hi wyldckat

I really appreciate your prompt reply and I will have a look at your info and let you know how I get on a bit later....

Thanks again!
