Dear Community,
I'm trying to build from sources foam-extended 3.1.
Platform: Fedora 20, x86_64
ThirdParties were properly downloaded by Allwmake.firstinstall but I had to set up all env-vars and compile them manually.
I'm stuck with such an error:
...

+ wmake libso multiSolver
+ wmake libso solidModels
+ wmake libso dbns
+ wmake all solvers

full log file in attachments. Can anyone send me a clue how to solve this problem ?

Greetings Michal,

I wanted to have a look into this myself, but I simply didn't manage to get enough time to test it.
Can you please detail the instructions you've followed and the steps you've taken to go around the problem you mentioned? Namely this one:

I ask this because the error messages you're getting are really strange and my feeling is that you might have installed something that is interfering with the usual installation set-up.

edit: I've tested this now in a virtual machine with Fedora 20 and was not able to reproduce the same error.

Best regards,
Bruno

Greetings Bruno,
It must be something wrong with dependencies OF-ext requires installed on my Fedora 20. Maybe imcompatible version.
I have downloaded rpm package from https://openfoamwiki.net/index.php/I...oam-extend-3.1
and successfully installed it with
sudo yum localinstall foam-extend-3.1-3.1-1.fc20.x86_64.rpm.

I needed postCalc.o file, so I cd to my foam-extended dir installed with rpm package, and run ./Allwmake. Unfortunately the same problem happens as in logs above. I bet it is something wrong with version of utilities OF-ext requires, not thirdparties of OF-ext.

Hi Michal,

This is indeed really strange. Perhaps your shell environment has loaded other OpenFOAM environments or even some other shell environment for another software toolbox?

By the way, what does the following command give you?

ls -l /etc/alternatives/ld

Does it give you a link to "/usr/bin/ld.bfd"?

Best regards,
Bruno

[kotu]

Hi Bruno,
Yes, it does.

/etc/alternatives/ld -> /usr/bin/ld.bfd

I don't know whether it had any sense but I ldd both libs ( ldd libfoam.so) (this build from source and
this from rpm package) and outputs are exactly the same.
Best regards
Michal

Hi Michal,

OK, then when in doubt, check where all pieces are coming from and which versions they are:

gcc --version
g++ --version
ld --version

which gcc
which g++
which ld

ls -l $(which gcc)
ls -l $(which g++)
ls -l $(which ld)

In addition, have you fully updated your Fedora 20 installation? I mean security updates and so on; I am not referring to an upgrade to Fedora 21 .

Best regards,
Bruno

Here's output:

Pretty standard I think.

Hi Michal,

Uhm, you didn't answer my last question, namely:

Dear Bruno,
I think yes. I perform every update instantly when OS gives me notification about.
Best regards

Hi Michal,

OK, then it's time to do some more hard-core debugging on this issue. Please run the following commands:

cd $FOAM_SRC/OSspecific/POSIX

wmake libo

SOURCE=regExp.C ;  g++ -m64 -Dlinux64 -DWM_DP -Wall -Wextra -Wno-unused-parameter -Wold-style-cast -Wnon-virtual-dtor -O3  -DNoRepository -ftemplate-depth-200  -IlnInclude -I. -I$FOAM_SRC/foam/lnInclude -I$FOAM_SRC/OSspecific/POSIX/lnInclude   -fPIC -c $SOURCE -o regExp.E -E

The last command will have created a new file named "regExp.E". Now the problem is how you'll get this file to me, because the one I've gotten, even when compressed with bzip2, was larger than the allowed maximum file size of 100kB for attachments here on the forum... Ah, OK, run the following commands:

split -b 500K regExp.E regExp.E_
gzip regExp.E_*

pwd

The location of the compressed files is given by the last command.
Then attach to your next post the files "regExp.E_aa.gz", "regExp.E_ab.gz" and other similar ones.

Best regards,
Bruno
