Sorry for asking a stupid ques
Sorry for asking a stupid question, perhaps nobody understood it. But since openfoam is open source, I really expected that someone could be helpful enough to explain why debug information is missing from this path:

/home/dm2/henry/OpenFOAM/linuxSrc/gcc-4.1.0/build/i686-pc-linux-gnu/libstdc++-v3 /include/bits/basic_string.h

I know you don't get paid for answering me, but isn't this so simple that it only takes 2 seconds to answer it?

I guess there are still some .
I guess there are still some .o or .so files lingering around which were built on Henry Wellers machine and not properly touched by your Allwmake. Use the find-command to find all .o and .so files in your OpenFOAM-installation that were created BEFORE your own building session and remove them. Then rebuild.

About that's part of the standard-C++-library: I think it's highly unlikely that problems with your programs stem from that.

This looks like a problenm with compiler relocation. I usually build mine into /usr/tmp, which makes it easier, but you should be able to easily build your own compiler. You can download gcc-4.1.1 source from one of the gcc sites. Then, remove the compiler from ~/OpenFOAM/linux/gcc-4.1.1 (just delete the directory + I am assuming you're using linux) and build your own using the following steps:

cd ~/OpenFOAM
mkdir linuxSrc
cd linuxSrc

Copy the compiler tar pack here (if you cannot find it, pls let me know and I will leave one for you somewhere convenient).

tar xzf gcc-4.1.1.tar.gz
mkdir gcc-4.1.1-obj
cd gcc-4.1.1-obj
../gcc-4.1.1/configure --prefix=~/OpenFOAM/linux/gcc-4.1.1 --enable-languages=c,c++ --enable-shared

Now build it:

gmake bootstrap

and install it:

gmake install

You can now delete the directories in ~/OpenFOAM/linuxSrc

As for the clean, OpenFOAM gives you a few scripts to clean the whole lot:

wcleanAll - cleans all the machines
wcleanMachile <build> - only cleans the named build, e.g. linuxGcc4DPDebug

Thanks Bernhard and Hrv, 1)
Thanks Bernhard and Hrv,

1) The first solution seems to be the easiest, but I'm afraid of deleting something that I shouldn't... I guess the first solution requires something like:

a) cd ~/OpenFOAM/OpenFOAM-1.3/ instead of cd ~/OpenFOAM ?

b) find . \( -iname *.so -o -iname _.o \) ! -newer ~/OpenFOAM/OpenFOAM-1.3/lib/linuxGcc4DPDebug -exec rm (or similar?)

2) The second solution is much more difficult to understand, but at least I don't think I'll delete something I need. I don't know what "compiler relocation" means, but if I type "which gcc" I get:

/home/martin/OpenFOAM/linux/gcc-4.1.0/bin/gcc, so I would expect that everything was okay as it uses the gcc-binary "associated" with OF.

I followed the steps to create linuxSrc and downloaded gcc-4.1.1.tar.bz2 which is a 38 KB file. It was unzipped with tar -xvjf (filename) and put into OpenFOAM/linux. It made a lot of files into ~/OpenFOAM/linux/gcc-4.1.1

I then created ~/OpenFOAM/linuxSrc/gcc-4.1.1-obj and inside that directory I did:

../../ (path to linux/gcc-4.1.1).../configure --prefix=/home/martin/OpenFOAM/linux/gcc-4.1.1 --enable-languages=c,c++ --enable-shared

Compilation seem to take pretty long - my 2 GHz laptop is compiling right now at this moment.... I wonder what it might be doing in all that time....

I also want to disable compiler optimization so I can better debug into the OpenFOAM source-code without "jumping" like when optimization was enabled in some other windows source code I have tried... How to get rid of that -O2 option in my next step, where I'll make some new linuxGcc4DPDebug-files... ?

I'll let you know whether I succeed or not in this task (I really hope I do) :-)

Oooh, damn... This is what
Oooh, damn...

This is what I did:

martin@laptop:~/OpenFOAM/linuxSrc/gcc-4.1.1-obj> ../../linux/gcc-4.1.1/configure --prefix=/home/martin/OpenFOAM/linux/gcc-4.1.1 --enable-languages=c,c++ --enable-shared

... followed by: "gmake bootstrap"

This is the last couple of lines from the above command:

............then mv -f ".deps/mf-runtime.Tpo" ".deps/mf-runtime.Plo"; else rm -f ".deps/mf-runtime.Tpo"; exit 1; fi

This is really really bad: if
This is really really bad: if your machine cannot compile gcc (one of the most standard and basic installations), you are likely to have more trouble later. I have seen something like this with some dodgy versions of RedHat Enterprise Edition, and they require additional packages to get them to work. I would suggest searching the web for help on compiling gcc.

This kind of thing should really just work with a decent version of linux.

I have suse 10.1, which I think is decent... But I must have screwed something up, somewhere in this process...

How about solution number 1? Is that possible?

If everything fails, I think I eventually will remove OpenFOAM and try to experiment by starting from scratch again and give it a couple of more shots again... Perhaps it'll work if I outcomment the OF-stuff that sets environment variables in bashrc, so it'll compile using the gcc binary in /usr/bin or wherever it is normally, instead of having a PATH environment that finds /home/martin/OpenFOAM/linux/gcc-4.1.0/bin/gcc

I'll try to see what I can come up with...

Hi Foamers,

I now got through the entire process and I don't think I got any serious errors... I think what might have caused me errors was that I probably forgot to remove the compiler from ~/OpenFOAM/linux/gcc-4.1.0 before starting out and the other thing I did was to compile as root (not sure if necessary though).

../gcc-4.1.1/configure --prefix=/home/martin/OpenFOAM/linux/gcc-4.1.1 --enable-languages=c,c++ --enable-shared

I now have gcc-4.1.1 in ~/OpenFOAM/linux, but many places (in path-environment) OF was looking for gcc-4.1.0 so since I didn't knew where to change that and be sure of having changed everything I did a "dirty" solution and created a symbolic/soft link in ~/OpenFOAM/linux: gcc-4.1.0 -> gcc-4.1.1

Then I did ./Allwmake and I think it worked...


Next problem: ParaFOAM won't start. It seems like some files are not compiled:

martin@laptop:~/OpenFOAM/martin-1.3/run/tutorials/icoFoam> paraFoam . cavity &

Okay, let's see if we can find module "":

martin@laptop:~/OpenFOAM> pwd

martin@laptop:~/OpenFOAM> find . -iname ""

Damn.... It only exists in the optimized compilation.

martin@laptop:~/OpenFOAM> pwd
martin@laptop:~/OpenFOAM> cd OpenFOAM-1.3/lib
martin@laptop:~/OpenFOAM/OpenFOAM-1.3/lib> ls -l linuxGcc4DPOpt | wc
57 450 3985
martin@laptop:~/OpenFOAM/OpenFOAM-1.3/lib> ls -l linuxGcc4DPDebug | wc
55 434 3953

Okay, it seems to me like 2 files are missing... What did I do in the first place?
In /home/martin/OpenFOAM/OpenFOAM-1.3/.OpenFOAM-1.3
I changed the file to this:

# Compilation options (default precision, optimised, debug or profiling)
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~


export WM_JAVAC_OPTION=Debug


What now? How to get ParaFOAM to work? I guess it wasn't necessary to make WM_JAVAC_OPTION=Debug but I thought why not...


unoder August 24, 2006 01:41

Hrv? Perhaps I should add t

Perhaps I should add that after running wcleanMachine linuxGcc4DPDebug and running the Allwmake-script, sometimes I got a message like this:

`/home/martin/OpenFOAM/OpenFOAM-1.3/lib/linuxGcc4DPDebug/' is up to date.

So I need "" - how to get it, if the Allwmake script doesn't make it?
