Here's a patch by Aleksei Nikiforov darktemplar@altlinux.org to make SimGear 2020.1.2 build against Boost 1.73.0 which misdetects "version" file for a header and tries to use it as such; see also http://git.altlinux.org/gears/S/SimGear.git?p=SimGear.git;a=commitdiff;h=12a55f903242a769b87b1021c23a1e2b8ba3112e
Merry Christmas!
2020.1 is an unsupported release, we'd recommend to use 2020.3 branch which is a long-term-supported version and the boost issue is already fixed. Does that work for you or do you need to stick with 2020.1 for some reason?
No need to stick, I was just a bit overloaded last year and managed to miss 2020.3 completely (only got down to these packages today and discovered the patch by my colleague and decided to upstream it); I'll take a look at the update; let's close this suggestion then, thank you!
Finally there, 2020.3.8 builds just fine, thank you!
