[llvm-dev] Help building llvm on freebsd 8.4

Hi,

Thanks for the information.

Is it possible to compile LLVM 3.8 in FreeBSD 10.x and eventually use/run
it on 8.4.
Our production environment is running 8.4 and we cannot update it.

Thanks,
Sushil Pangeni

You can run FreeBSD 8 executables on FreeBSD 10, but not the other way around.

If you absolutely must use FreeBSD 8, I think your best shot is to install a gcc
port (at least version 4.8, since that is the first with reasonable C++11
support), and use that to compile llvm.  E.g. if you install the gcc48 port,
use:

cmake -DCMAKE_C_COMPILER=/usr/local/bin/gcc48
-DCMAKE_CXX_COMPILER=/usr/local/bin/g++48 $LLVM_SOURCE_DIR

Before attempting to do so, patch up your /usr/include/stdlib.h like this:

--- include/stdlib.h	2016/03/23 18:21:26	297211
+++ include/stdlib.h	2016/03/23 19:17:12	297212

You will most likely have to manually apply
https://svnweb.freebsd.org/base?view=revision&revision=297212 though, as I
have not merged that back to FreeBSD 8.

But what about a statically linked clang-3.x where x >= 5, and running that
on
FreeBSD 8?
