Question on compiling on Linux

[GuilleNM]

Hi, I am trying to install OpenFast ona Ubuntu virtual machine and I was following the intallation steps on the openfast.readthedocs guide and I keep getting this error which I cannot find a way to fix. When I try to compile eveything it starts to compile each item but it freezes at 85% and after a while it gives that error. I tried installing and updating all the other tools and libraries and they seem to be up to date. Any idea of how to fix this issue?

Hi @GuilleNM

Which version of gfortran are you using? And which branch/version of OpenFAST? How much memory do you have available on the virtual machine?

I suspect that gfortran runs out of memory during compilation and fails. The FAST_Types.f90 takes a lot of memory during compilation. If this is the actual cause, there are two possible solutions:

1. Increase the amount of memory in the virtual machine
2. reduce the optimization on the compilation of the FAST_Types.f90 file. Depending on exactly which branch or version of OpenFAST, this may already be reduced to -O2 for the Intel compiler suite, but may also be needed for the gfortran compiler you are using on this VM. This setting is in the modules/openfast-library/CMakeLists.txt file (lines 72:75). You can comment out the if statement so that the set_source_file_properties statement applies to all compilers, and see if this helps.

Hope this helps,
Andy

@GuilleNM Do you need to compile the code? Check out this section of the installation documentation: https://openfast.readthedocs.io/en/main/source/install/index.html#download-binaries
