Hi,

I believe the ulimit issue is due to copying and pasting from the code from the wikipage (which is not plain text). If you do this, you won't be able to save the bashrc the file in the "Western (Mac OS Roman)" format and it will force you to save as "Unicode (UTF-6)", or something like that. You need to just type in the two line of code manually and then you'll be good.

Hi dsh5400 and welcome to the forum!

Thanks for the input! I've updated the wiki page to reflect your feedback: http://openfoamwiki.net/index.php/Ho...hes_and_tweaks

Best regards,

After building openfoam, I got this message " Target `application' not remade because of errors.".
building took more than 24 hrs....

make.log.tar.gz

Greetings Heba and welcome to the forum!

Did you read and follow to the letter what is written here: http://openfoamwiki.net/index.php/Ho...enFOAM_v21_Mac

Because the errors that I could see in your log file indicate two or more problems:

• Incorrect gcc version - the instructions show that you should have 4.6.
• The file system being used isn't case sensitive. It's pointless to move an unpacked OpenFOAM folder from a case insensitive to a case sensitive file system.
• ThirdParty folder not found.

Good luck!
Bruno

Yes I followed all instructions....
but when I type 'gcc -v' it indicates the version is 4.2.1 and when I type 'gcc-mp-4.6 -v' it indicates the version is 4.6
sorry if it seem to be stupid
Thanks

Hi Heba,

Sorry about that, I don't have a Mac to proof-test the instructions and only after your log file did I make the connection. The instructions were missing an important step - http://openfoamwiki.net/index.php/Ho...hes_and_tweaks :

Open the file "OpenFOAM-2.1.0/etc/bashrc" with a text editor, e. g. Text Wrangler, pico or nano and:

1. Find this line:
   

   export WM_COMPILER=Gcc

   And change to this:
   

   export WM_COMPILER=Gcc46

Best regards,
Bruno

Thank you for replaying...I will rebuild it again..but not now because while building I cannot interact with my laptop and it takes more than 24 hrs...is that normal ?

If you don't have much memory (<2Gig) and an old Laptop this is possible (some of the templated code takes a lot of memory to compile especially if you're using -O3 - check with a top in another terminal).

Also make sure that WM_NCOMPPROCS is not set. If 2 or more compilers run in parallel on a Single-core then the problem gets worse ("the swap of death")

Starting the compilation with

nice ./Allwmake

should also make it ... nicer

[heba]

well, how can I test that WM_NCOMPPROCS is not set ?

1. Check how many cores your machine has:

   sysctl -n hw.ncpu

   If it says 4, then you can either use 2 or 3 and still have enough CPU power for some other activities. Like Bernhard said, you should also take into account the amount of RAM your machine has free. The task manager or system monitor or whatever it's called on a MAC can tell you how much RAM is available.
   My rule of thumb (on Linux) is that around 1.7 GB is enough for using 4 cores; 1.3GB is the bare minimum for single-core, at least a few years ago.
2. Edit the file "OpenFOAM-2.1.0/etc/bashrc" once again and go to the end of the file and edit the line with "export WM_NCOMPPROCS=..." and place a suitable value at "...". For example:

   export WM_NCOMPPROCS=2

3. Start a new terminal window, just to make 100% certain that you're starting with a clean shell environment. Then do this step: Source bashrc
4. To check what value is set for "WM_NCOMPPROCS" run:

   echo $WM_NCOMPPROCS

5. To turn it off:

   unset WM_NCOMPPROCS

Good luck!
Bruno

Hi,
I have that error when applying the patch of ThirdParty

Hunk #1 FAILED at 1.
1 out of 1 hunk FAILED -- saving rejects to file scotch_5.1.11/src/Makefile.inc.rej

Whats in that file? Because that says "I can't apply THESE changes because the original file is different from what I'm expecting"

Seems like the line

../../etc/wmakeFiles/scotch/Makefile.inc.i686_pc_linux2.shlib-OpenFOAM-64

Is no longer in the file. Look for a similar line and replace it with

./../etc/wmakeFiles/scotch/Makefile.inc.i686_mac_darwin.shlib-OpenFOAM

That's just a symbolic link reference. It will be automatically re-generated by Allwmake, so I think that error can be ignored

Thanks guys!

I've a problem, I have installed openmpi via port but when I source etc/bashrc I can run openmpi anymore. Is this a problem?

My compilation has crashed after 3 hours.

[wyldckat]

Greetings Theo and welcome to the forum!

There is a subsection on what to do when things go wrong See here: 2.6.1 Diagnosing problems

If you want to do parallel runs: yes

I used to have similar problems with 10.6 because the preinstalled openmpi clashed with the MacPorts-version. Which OS-version do you have

What do you mean with crash? Or do you mean it reports some errors in the end? (depends on the errors whether this is a problem)

[theoenderest]

I have Lion 10.7. I got allot of error 2 messages. I threw the whole partition away out of anger. Also the first instance when running the patch-Mac-gcc46 it gave errors.

I'm trying to install it on a memory stick not on a partition on the hard drive do you think this could be the problem? (it is partitioned journaled case sensitive.)

I'm going to get some rest first tonight and maybe try tomorrow again. :P I've done all the step 3 times now without success. :P I'll post my logs tomorrow, I'm sorry I didn't post it, but this is very new for me, I'm just learning.
