CFD Online Discussion Forums - Meson reconfigure issue with Autodiff enabled

Hello there,

I encountered the following error when I tried enabling the autodiff feature in SU2:

Code:

ninja: Entering directory `build'

[1/4] Generating 'SU2_PY/pySU2/_pysu2ad.so.p/pySU2ad.cxx'.

FAILED: SU2_PY/pySU2/_pysu2ad.so.p/pySU2ad.cxx

ninja: build stopped: subcommand failed.

I had no issue in setting up the directdiff feature. ninja builds it fine when only directdiff is enabled, similarly pysu2 also works fine, SU2 also works fine with mpi. I ran the Quickcase using a python script in parallel mode and it worked fine, I could also extract lift, drag and other values. But when I try enabling autodiff using meson and try to use ninja build, it fails completely and results in the error above:

Can someone comment on what's the issue here? I read somewhat similar issues in the github page (eg.: https://github.com/su2code/SU2/issues/1568 ) but my issue is slightly different I guess. Any help is much appreciated
