compilation problems

[AlexWagnerGO]

Dear folks,

we have an issue compiling the code on a UBUNTU 20.04.
We are using a gcc 9.3 compiler and receive the error below. We tried compiling on several machines, the issue is always the same. We would appreciate some help.

Thanks,
Cheers,
Alexander from DLR Göttingen

Hi Alex,

Which D compiler are you using at the moment?

[AlexWagnerGO]

Hi Lachlan,

we are using Ldc version (1:1.20.1-1).
Cheers

[Whyborn]

What revision of the code are you using? The most recent version does not have these thermo update functions flagged as @nogc, so I don't think you should be seeing those errors. As for the isClose issue, try using a newer version of the LDC compiler. I think I remember having that problem when we switched from approxEqual to isClose. At the moment I can't replicate the issue you're having.

Hi Alex,
I'll echo Lachlan's advice: we recommend latest revision of the gdtk source code and latest revision of the ldc compiler. Our continuous integration bot gives us a high degree of confidence in clean builds with the latest revisions.
Cheers,
Rowan

Solved with your advice. Thank you very much folks!
