This is very strange.

Are you able to generate 1.0 FMUs from the latest version of E+ToFMU?

Do you have right permissions on that machine?

Thanks!

Hi, I´m learning PyFMI for co-simulating E+ and HVAC FMUs. I´ve been able to create FMU 1.0 from earlier E+toFMUs versions and do co-simulation using dymola as master. However, in PyFMI the master algorithm only supports 2.0 FMUs:
"pyfmi.fmi.FMUException: The Master algorithm currently only supports CS 2.0 FMUs"

E+toFMU V3.0 adds supports for the FMI for Co-Simulation version 2.0. However, when I try to generate the E+ FMU2.0 I got the following error:

""Failed to link "_london_office.dll"
ERROR from script file {utilManageCompileLink.pyc}
Failed to link object files into {_fmu_export_schedule.dll}""

Does anyone know why? Or why it´s allowing me to create 1.0 FMUs and not 2.0
I´m working in 64win, using VS 14.0
Thanks

Dear Thierry, yes, I´m able to create FMU 1.0 and make some tests with dymola as master.

But when I specify ""-a 2 "" for FMU 2.0 I receive an error. I think it has to be with the compiler or linker or maybe the code´s not identifying my system as x64 and thus, E+toFMU is choosing the win32 source code for generating the proper libraries...

""""Reading input and weather file for EnergyPlusToFMU program.

I tried VS 12.0, 14.0, v.2019, linking the respective .bat files in V3.0 scripts, and also switching to x64 dev prompt (as suggested by user:yapan in an earlier post in this group); however without success.

I will appreciate any insight. I'm currently using win x64, E+9.3.0/9.0.1, VS 2019, python 2.7

Thanks!

Hi Thierry,

Following this issue, I realized that I´ve had a preinstalled x86 version of python on my computer. I removed it and installed 2.7 x86-64 version

By doing that, I was finally able to generate an FMU 2.0 from E+ with its respective 64 binaries
