Calypso: Direct and full interfacing to C++

[Kelly via Digitalmars-d-announce]

Hello Elie,

Ok, I tried to build on OS X with the LLVM/Clang revisions from 
above and
the Calypso/LDC code from my github fork, but it is a no go.

Calypso compiles pretty easily, but there are issues with 
"vector" not being
found, so then I install libc++ so that clang easily picks up the 
correct
include directories.

Then "unistd.h" isn't found...ok it turns out XCode Command Line 
Tools needs
to be installed to get some gcc specific files, but the internal 
Calypso
call to clang needs to be modified.

Change Calypso to call 'xcrun --show-sdk-path`, because this 
seems to work
from the command line. Needs to be run from a shell...ugh. Etc, 
etc.

Run into problems with libc++ and libstdc++ colliding. Remove 
libc++. Ugh.

I finally just compile things by hand and get through to Calypso 
running
and producing a bunch of object files, but then gcc won't link in 
  some allocator code from stdc++?? Sheesh, not sure what is going 
on...I have
tried several different ways to fix this, to no avail.

Anyways, I am tired so I will just have to mess with this some 
more tomorrow
or the next day. Hopefully I can figure out what is going on as 
it seems
close to working.

There might be real issues with someone having libc++ and 
libstdc++
alongside XCode tools like I had.


Thanks,
Kelly

P.S. I try out Calypso from your github repo most days and the
vector/bitset/showcase examples weren't working with todays code 
-->
"Do not call _d_invariant on C++ class objects". Just to make 
sure you
are aware of it.
