Hello,
Initially I reported this issue at [0003696: Build failure on Linux ARM64 for ThirdParty-dev - OpenFOAM Issue Tracking](https://bugs.openfoam.org/view.php?id=3696) but I’ve been recommended to discuss it here.
I am trying to build OpenFOAM on Ubuntu 20.04.2 ARM64.
The build fails for ThirdParty-dev, master branch.
I follow the instructions at [OpenFOAM Repo: 1. Software for Compilation | OpenFOAM](https://openfoam.org/download/source/software-for-compilation/)
1. sudo apt-get install build-essential flex bison git-core cmake zlib1g-dev
2. sudo apt-get install libqt5x11extras5-dev libxt-dev qt5-default qttools5-dev curl
3. git clone [GitHub - OpenFOAM/OpenFOAM-dev: OpenFOAM Foundation development repository](https://github.com/OpenFOAM/OpenFOAM-dev.git)
4. git clone [GitHub - OpenFOAM/ThirdParty-dev: OpenFOAM-dev third-party library compilation scripts](https://github.com/OpenFOAM/ThirdParty-dev.git) && cd ThirdParty-dev
5. source $HOME/OpenFOAM/OpenFOAM-dev/etc/bashrc
6. ./Allwmake
7. ./makeParaView
and here it breaks with:
…

The linked OpenFOAM issue shows that it is actually an error in OpenFOAM code and nothing to do with ParaView. Parallel builds with `make` usually need some scrolling to find the actual error message (`make -j1` will certainly stop at the “first” error at least).

Hi @ben.boeckel ,
In the OpenFOAM issue only the first entry is about ParaView (in their ThirdParty-dev repo there is `makeParaView script). I have copied the last part of its output here too.
The later comments are about OpenFOAM itself. There I use `-j` for `Allwmake` script.
Now I modified [ThirdParty-dev/ParaViewFunctions at 1ff0136d3279590bd2e1f2e408349e851b7d7e38 · OpenFOAM/ThirdParty-dev · GitHub](https://github.com/OpenFOAM/ThirdParty-dev/blob/1ff0136d3279590bd2e1f2e408349e851b7d7e38/etc/tools/ParaViewFunctions#L533) to use `make -j 1` when building ParaView and re-run it. I will copy the new error once it finishes.
Regards,
Martin

Here is the new error with `make -j 1`:

OpenFOAM uses ParaView 5.6.3, so this issue might have been already fixed!

Yes, that was fixed at some point already 🙂 . The fix is to go and dig into `png`'s headers and just mask out that NEON is supported at all by hacking up the processor detection routines.
