Is there an aarch64 version of EnergyPlus? Or how to compile the aarch64 version from the source code

Maybe start here? https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html

[eringold]

also see: #8664

[jmarrec]

Either checkout #8664 or do this: specificy CMAKE_OSX_ARCHITECTURES

cmake -DCMAKE_OSX_ARCHITECTURES=arm64 [...]

Alternatively, I think this should also prefill the CMAKE_OSX_ARCHITECTURES correctly

export ARCHFLAGS="-arch x86_64"
cmake

Once the arch is detected correctly, I can assure you that EnergyPlus builds and runs fine.

@fubingting I uploaded an aarch64 version on the release page: https://github.com/NREL/EnergyPlus/releases/tag/v9.5.0

EnergyPlus-9.5.0-de239b2e5f-Darwin-macOS11.2-arm64.dmg
EnergyPlus-9.5.0-de239b2e5f-Darwin-macOS11.2-arm64.tar.gz

Could you give it a shot?

Thank you very much. I'll try to install it.

After downloading and decompressing, I execute the three energyplus-9.5.0,EPMacro,ExpandObjects commands, and the following error occurs:

**./energyplus-9.5.0**
-bash: ./energyplus-9.5.0: cannot execute binary file: Exec format error
**file energyplus-9.5.0**
energyplus-9.5.0: Mach-O 64-bit arm64 executable, flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|WEAK_DEFINES|BINDS_TO_WEAK|PIE>

@fubingting what OS/Version are you using? This package is specifically for an M1 mac.

[fubingting]

platform：aarch64
os：centos8
Because you mentioned above

[jmarrec]

I assumed you were using an M1 mac incorrectly. The name of the installer mentions darwin-macos11.2-arm64 so I thought it was explicit that this would work on macOS only.

We do not have a centos aarch64 package no.

[jmarrec]

#8664 was merged, so you should try to compile it from source. https://github.com/NREL/EnergyPlus/wiki/Building-EnergyPlus

You'll need cmake and a C/CXX compiler, and that should pretty much be it as far as dependencies. I suggest a fortran compiler too so you can build the auxiliary programs such as ReadVarEso and ExpandObjects.

Hi @jmarrec, I tried to compile EP on M1, everything seems to work fine with binaries directly from the build folder. But after I installed the compiled package in the Applications folder, a few binaries do not work and give the error

zsh: killed     ReadVarsESO
zsh: killed     ExpandObjects
...

while bash gives

Killed: 9

I did not test all binaries exhaustively. Two I found working are energyplus and EPMacro. I tried compiling 9.6, also installing the precompiled 9.5 you attached above. Any ideas why this might be?

I can open a new issue if more appropriate.

[jmarrec]

I'm closing this issue as it works as intended. I'm moving @airallergy 's issue with M1 mac to #9303
