If the superbuild created the lagom binary directory, it won't set
BUILD_LAGOM=ON in the CMake cache for that binary directory. Insert a
check into build_target() to make sure that if the user explicitly asks
for the lagom target, we have all our ducks in a row.
Direct build commands to the SuperBuild's binary directory, and
image/run commands to the Serenity binary directory.
As a side benefit, make the lagom target only build Lagom instead of the
entire OS alongside Lagom.
This environment variable is already widely used across our build
scripts and tooling, so serenity.sh should respect it as well.
It still uses i686 as the fallback.
This command copies the project's source tree to
/home/anon/Source/serenity in the built disk image.
This will be useful for working on serenity inside serenity :^)
This was brought up as something that would be useful by
`RealKC` on the discord, and I happened to agree that it
would be useful. Especially given the abundance of Toolchain
changes recently.
This change fixes two bugs:
1) If you run `serenity.sh` outside of your serenity git clone, the
`get_top_dir()` function won't be able to auto detect the serenity
root dir and we'll error out. By allowing the script to use an
existing $SERENITY_ROOT vlaue if it exists, we can solve
this problem.
2) If tried to run a command which ends up calling `build_toolchain()`
and you were outside of the root of the project, it should just
fail. Fix this by utilizing `$SERENITY_ROOT`.
I have this symlinked into ~/bin, when looking at the help/usage
it would previously print the fully qualified path to the script
making the help very difficult to read.
Running the tests will be moved to a separate test command which can
then leverage the availability of different targets and run either unit
tests on the host or the image in QEMU in self-test mode. :^)
- Only call ensure_toolchain for non-lagom targets
- Use host addr2line, we can't expect the i686 toolchain's addr2line to
support the host's binary executable format
- Don't export SERENITY_ARCH and TOOLCHAIN_DIR, don't need them anymore
