Dear Sam,
I have no experience with clang (I use gcc on Mac). May be, the add of
the "explicit" c++ keyword on the definition of the constructors for the
class
ga_workspace (lines 593 and 595 of src/getfem/getfem_generic_assembly.h)
could help.
Best regards,
Yves

Hello all,
I'm currently attempting to build getfem for Mac with the current
clang (LLVM 9.1.0) and am getting this error:

This seems to occur wherever a ga_workspace object is assigned from
using "=", for instance
local_workspace = gaf.local_workspace;
(from getfem_generic_assembly_functions_and_operators.cc, line 708).
I'm already way out of my depth here but haven't found anything
helpful just googling around, nor have I been able to replicate the
error from scratch. If anyone has dealt with this or understands what
clang is on about, I'd love to hear it!
Thanks,
Sam
