That function doesn't exist anymore, or even that file.  Care to try a newer version?

Indeed...

I've downloaded the version on gdcproject.org, but same result...

$ ./gdc --version

gdc (gdcproject.org 20161225-v2.068.2_gcc6) 6.3.0

$ ./gdc -m64 recast.d

recast.d:1:0: internal compiler error: in get_symbol_decl, at d/d-decls.cc:136

And couldn't install gdc via your PPA, it says there is not support for Xenial...

Please could you simply download the latest file from Github and compile locally with your own version of gdc.

https://github.com/senselogic/RECAST/blob/master/recast.d

If it compiles fine with your version, then I know it's just a compiler version problem, not a compiler bug, and this will eventually be solved once I will be able to use the same version as you :)

I initially got a link error, but when pushing out phobos 2.076 it worked fine.

The internal error in both places seem to suggest a bug in earlier versions of the front-end, in particular, a bogus Dsymbol was passed to the backend.

You're going to have to try multiple versions of dmd here, possible starting from 2.066 or 2.068, and noting any differences between versions.

What I expect you to find is, that 2.066 ICE'd, 2.071 works, 2.075 regressed and has linker errors, and 2.076 is fine again.

It works !!!

With the 2.076 version everything is all right now :)

Thank you so much Iain for all your efforts to help me solve this problem !!!

Closing, as there's no issue here.
