Hi everyone.
I have a problem installing Openfoam-v1912 (in mac-catalina) from source through the following link:https://www.openfoam.com/download/install-source.php

I have followed the steps as given in the above link, that is:
I have installed the necessary .tgz:
mkdir $HOME/OpenFOAM && tar -xzf OpenFOAM-v1912.tgz -C $HOME/OpenFOAM && tar -xzf ThirdParty-v1912.tgz -C $HOME/OpenFOAM

but I get the following flag when I am sourcing the OpenFoam environment: (source ~/OpenFOAM/OpenFOAM-v1912/etc/bashrc)
Darwin support is clang/llvm only

Hence, I installed both the clang and llvm: (below I give the proof for that)

============
clang --version
Apple clang version 11.0.0 (clang-1100.0.33.17)
Target: x86_64-apple-darwin19.3.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

brew info llvm
lvm: stable 9.0.1 (bottled), HEAD [keg-only]
.....
build -error: 0 (30 days)
===============

But I still get the same flag.
As a result, I get the folllowing error when I test the system readiness in the Compilation section of the guide: https://www.openfoam.com/code/build-guide.php

================
foamSystemCheck

Checking basic system...
-----------------------------------------------------------------------
Shell: /bin/bash
Host: Kotsioss-MacBook-Pro.local

Your system is not currently compatible with OpenFOAM installation
requirements. Review the error messages and consult the documentation

Any advice?

Hi,

You can try to ignore the error Since foamSystemCheck utility is not adapted for macOS installations (maybe you should submit a bug report):

# check os
OSTYPE=$(uname -s)
case "$OSTYPE" in
Linux | LinuxAMD64 | SunOS )
    echo "$(fixlen OS: $WIDTH) $OSTYPE version $(uname -r)"
    ;;
*)
    echo "ERROR: Incompatible operating system \"$OSTYPE\"."
    echo "       OpenFOAM $WM_PROJECT_VERSION is currently available for "
    echo "       Linux, LinuxAMD64 and SunOS only."
    echo
    fatalError=true
    ;;
esac

Do you have case-sensitive file system in your home folder?

UPD. There is compilation problem, so you can not, in fact, install this version without patching.

[madgeogr]

Hi alexeym,
thanks for the advice. I will consider installing another version.
In the process, I have also encountered another issue, related to Catalina version (again).
In particular, "Apple has changed the default shell to zsh. Therefore you have to rename your configuration files. .bashrc is now .zshrc and .bash_profile is now .zprofile."
https://stackoverflow.com/questions/...ed-by-my-shell
I have created a .zshrc file, but I am confused on how to move forward from there.

[alexeym]

Hi,

Modification, necessary to fix compilation, is quite small, in fact. Clang can't resolve certain templates, so call to std::max_element produces an error. Another error, which can be ignored, is in cfMesh and is related to OpenMP.

So ad-hoc fix is something like (later HashTable::iterator code should be fixed)

diff -r a/src/OpenFOAM/containers/Bits/bitSet/bitSetTemplates.C b/src/OpenFOAM/containers/Bits/bitSet/bitSetTemplates.C
78c78,85
<     const auto max = std::max_element(first, last);
---
> #ifdef __APPLE__
>     auto max = first;
>     for(; first != last; ++first)
>         if (*max < *first) max = first;
> #else
>     auto const max = std::max_element(locations.begin(), locations.end());
> #endif
>     // const auto max = std::max_element(first, last);
diff -r a/src/OpenFOAM/containers/HashTables/HashOps/HashOps.C b/src/OpenFOAM/containers/HashTables/HashOps/HashOps.C
82a83,89
> #ifdef __APPLE__
>     labelHashSet::const_iterator first = std::begin(locations);
>     labelHashSet::const_iterator last = std::end(locations);
>     labelHashSet::const_iterator max = first;
>     for(; first != last; ++first)
>         if (*max < *first) max = first;
> #else
83a91
> #endif

There was no such error in v1812. Did not try v1906.

Concerning zsh, you can add

export BASH_SILENCE_DEPRECATION_WARNING=1

to your .bash_profile (or .profile) to remove warning and continue to use bash. Also IIRC zsh was quite happy to source OpenFOAM's bashrc.

[madgeogr]

Hi,
thanks for your help.
I follow your advice, meaning that I included the additional code in the .C files,
and I also added "export BASH_SILENCE_DEPRECATION_WARNING=1" in the
.bash_profile at the home directory. Then I sourced the environment. But when I use ./Allwmake, I got the following:

Hi,

As it was said in warning during "source etc/bashrc" step, currently there are build rules only for Clang on macOS. Yet, for some reason you are trying to access Gcc build rules:

...
.../OpenFOAM-v1912/wmake/rules/General/general:33: .../OpenFOAM-v1912/wmake/rules/darwin64Gcc/general: No such file or directory
...

Could you post output of

export | grep WM_

after you sourced etc/bashrc?

[madgeogr]

Sure,
after I sourced the OpenFoam environment:

Kotsioss-MacBook-Pro:OpenFOAM-v1912 kotsios$ source etc/bashrc
Darwin support is clang/llvm only

I execute the following command:

Kotsioss-MacBook-Pro:OpenFOAM-v1912 kotsios$ export | grep WM_
declare -x WM_ARCH="darwin64"
declare -x WM_COMPILER="Gcc"
declare -x WM_COMPILER_TYPE="system"
declare -x WM_COMPILE_OPTION="Opt"
declare -x WM_DIR="/Users/kotsios/OpenFOAM/OpenFOAM-v1912/wmake"
declare -x WM_LABEL_OPTION="Int32"
declare -x WM_LABEL_SIZE="32"
declare -x WM_MPLIB="SYSTEMOPENMPI"
declare -x WM_OPTIONS="darwin64GccDPInt32Opt"
declare -x WM_PRECISION_OPTION="DP"
declare -x WM_PROJECT="OpenFOAM"
declare -x WM_PROJECT_DIR="/Users/kotsios/OpenFOAM/OpenFOAM-v1912"
declare -x WM_PROJECT_USER_DIR="/Users/kotsios/OpenFOAM/kotsios-v1912"
declare -x WM_PROJECT_VERSION="v1912"
declare -x WM_THIRD_PARTY_DIR="/Users/kotsios/OpenFOAM/ThirdParty-v1912"



Thanks again

[alexeym]

The problem is here:

WM_COMPILER="Gcc"

Som either you source bashrc like this:

WM_COMPILER="Clang" source etc/bashrc

or you create $HOME/.OpenFOAM/prefs.sh with corresponding export. Mine is like this:

WM_COMPILER=Clang
WM_COMPILE_OPTION=Opt
WM_MPLIB=SYSTEMOPENMPI
WM_PRECISION_OPTION=DP
WM_LABEL_SIZE=32
export WM_NCOMPPROCS=$(sysctl -n hw.ncpu)

[madgeogr]

Hi,
sorry again for bothering you, but it still does not work. I did as you said, meaning:
WM_COMPILER="Clang" source etc/bashrc

and I got again the following flag:
Darwin support is clang/llvm only

Then, I went into to the bashrc and I changed the compiler there from Gcc to clang:
# [WM_COMPILER] - Compiler:
# = Gcc | Gcc4[8-9] | Gcc5[1-5] | Gcc6[1-5] | Gcc7[1-4] | Gcc8[12] |
# Clang | Clang3[7-9] | Clang[4-6]0 | Icc | Cray | Arm | Pgi
export WM_COMPILER=Clang

but still nothing happened. Then, I created the prefs.sh in $HOME, and I paste inside
---------
WM_COMPILER=Clang
WM_COMPILE_OPTION=Opt
WM_MPLIB=SYSTEMOPENMPI
WM_PRECISION_OPTION=DP
WM_LABEL_SIZE=32
export WM_NCOMPPROCS=$(sysctl -n hw.ncpu)
---------

But nothing again. To be honest, I do not understand what I am doing. Do you recommend any other version of OpenFoam that I might avoid all these troubles?
And thank you very much again for your help, it is appreciated

[alexeym]

Hi,

Whole idea behind this forum is to bother people

It is not quite clear what do you expect. You will always get this message:

Darwin support is clang/llvm only

Since it is always displayed on macOS. Surely it would be nice if ESI adds WM_COMPILER variable reset for Darwin in future releases.

As soon as you have WM_COMPILER set to Clang you can try to compile software.

You choose OpenFOAM version according to required functionality. There are certain things only available in ESI's OpenFOAM. If you can not compile software, you can always use it inside Docker image (https://openfoam.com/download/install-binary-mac.php).

Personally I use Foundation's OpenFOAM flavour. You can easily find native build guide for macOS using preferred search engine.

[madgeogr]

Alexey,
I also changed the compiler to "Clang" in the cshrc file, I sourced the environment, and I "./Allwmake". The last five minutes the OpenFoam was compiling, until I got the following error:

/Library/Developer/CommandLineTools/usr/bin/../include/c++/v1/cstring:89:9: error: no member named 'strtok' in the global namespace
using ::strtok;
~~^
fatal error: too many errors emitted, stopping now [-ferror-limit=]
20 errors generated.
make: *** [/Users/kotsios/OpenFOAM/OpenFOAM-v1912/build/darwin64ClangDPInt32Opt/src/OSspecific/POSIX/POSIX.o] Error 1

At least there is progress i guess

Any further advice?


PS: Regarding docker: At first I installed docker, and the code worked fine. But I need to implement a turbulence model in the code, thus I needed the source code as well.

[madgeogr]

Alexey,
I show an another thread a similar issue as mine:
OpenFOAM 5.x (mrklein patch) and macOS High Sierra
in which the same error occurred:/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/cstring:89:9: error: no member named 'strtok' in the global namespace

It is mentioned that the problem was solved after a clean installation.
In order to do that, I found on the internet that I have to implement the follow steps:
$> cd $WM_PROJECT_DIR
• $> ./wcleanAll
• $> ./Allwmake

The problem is that I do not find wcleanAll (i found different "cleans" in wmake folder):
./wcleanAll
-bash: ./wcleanAll: No such file or directory

Any additional patches?

[alexeym]

And we have arrived to the question, I have asked in my first reply [1]: is your home folder located on a case-sensitive file system?

Usually on macOS it is case-preserving but case-insensitive. So, for example, string.h and string.H point to the same file (the reason for your error). string.h is a system header, string.H is OpenFOAM's header file. Later you will encounter errors due to time.h and Time.H name clash.

Guess, the way to proceed is to clean OpenFOAM folder. Create disk image with case-sensitive file system (you can find necessary commands here: https://github.com/mrklein/openfoam-os-x/wiki). Mount this disk image into $HOME/OpenFOAM and restart build process.

1. Problem installing OpenFoam-v1912 from source

[madgeogr]

Thanks Alexey,
I will try that.
Have a good night!

[madgeogr]

Hi Alexey,
I have a problem (again) when i am following the instructions as given in https://github.com/mrklein/openfoam-...ase-&-Homebrew
In particular, I have followed the steps without any problem until when I had to apply the patch with git:
git apply OpenFOAM-v1912.patch
When I opened the patch file, I show the flag: 404: Not Found. Where can I find the patch? When I visited your site, I show that you have patches for different versions of OpenFoam, but not for v1912.
If I download the most recent one, "OpenFOAM-7-0ebbff061.patch" and execute "git apply OpenFOAM-7-0ebbff061.patch" instead, do you think it will be OK?

[madgeogr]

Thanks Alexey,
I eventually used your patches for Openfoam 6 and now OF works properly. Thank you very much for your time!
