Adding libcxx and libcxxabi to llvm?

Lenard Spencer · 02-13-2017, 11:27 AM

I just came across a program that requires libc++abi.so.1, and in checking into it I found that that library is from libcxxabi, which is a project of llvm. What are the pitfalls of adding libcxx and libcxxabi to the llvm package?

(The program in question is the X-Plane 11 installer.)

Thanks in advance.

UPDATE: In looking at the SB script for llvm, I came up with this patch. Maybe it could be incorporated into llvm?

The files needed are libcxx-3.x.x.src.tar.xz and libcxxabi-3.x.x.src.tar.xz. (3.8.0 for 14.2 and 3.9.1 for -current) The patch:

(note that the last line after 'rm -rf $PKG/usr/docs' is a single space with a return.)

So far it seems to work for me.
