Use libtool for liblxc.so This should allow proper filtering of build flags for libraries and make it easier to use PIE/PIC. Signed-off-by: Stéphane Graber <stgraber@ubuntu.com>

Use /usr/bin/env python3 instead of /usr/bin/python3 project-wide This fixes invocations of certain commands when python3 is installed in a nonstandard path (/usr/local/bin, for example). Signed-off-by: Fox Wilson <2016fwilson@tjhsst.edu>

build: Make setup.py run from srcdir to avoid distutils errors distutils can't handle paths to source files containing '..'. It will try to navigate away from the build directory and fail. To fix that, before building the python module, transform all the path variables then cd to the srcdir, and set the build directory manually. This is hopefully the last needed fix to use separate build and source diretories. Signed-off-by: Daniel Miranda <danielkza2@gmail.com> Acked-by: Stéphane Graber <stgraber@ubuntu.com>

build: Fix support for split build and source dirs Building LXC in a separate target directory, by running configure from outside the source tree, failed with multiple errors, mostly in the Python and Lua extensions, due to assuming the source dir and build dir are the same in a few places. To fix that: - Pre-process setup.py with the appropriate directories at configure time - Introduce the build dir as an include path in the Lua Makefile - Link the default container configuration file from the alternatives in the configure stage, instead of setting a variable and using it in the Makefile Signed-off-by: Daniel Miranda <danielkza2@gmail.com> Acked-by: Stéphane Graber <stgraber@ubuntu.com>
