Which exact debian you're on? Our script installs llvm-dev package, which is default to 3.5 for Debian Jessie and it's 3.6 for Stretch and Sid.
You might try the following: - Use --ver-llvm=3.5 command line argument to force LLVM 3.5 to be used. This might result in C++11 issues i've mentioned above. - Use --force-llvm command line argument to force llvm-3.4 to be locally compiled and installed to /opt/lib. This will match the release environment in fact. On Fri, Mar 18, 2016 at 8:53 PM, Owen Hogarth II <[email protected]> wrote: > quick update > > I just received response from the OSL guys.
