Globally linking to anything isn't a good thing to do and this doesn't
seem to be necessary. If it ends up breaking any platform it can be
readded as a specific link later.
Add GTK as a possible GUI framework alongside Qt on Linux. When the gtk
or qt vcpkg manifest feature is selected, the corresponding framework
dependencies are pulled in automatically.
Use mimalloc for Ladybird-owned allocations without overriding malloc().
Route kmalloc(), kcalloc(), krealloc(), and kfree() through mimalloc,
and put the embedded Rust crates on the same allocator via a shared
shim in AK/kmalloc.cpp.
This also lets us drop kfree_sized(), since it no longer used its size
argument. StringData, Utf16StringData, JS object storage, Rust error
strings, and the CoreAudio playback helpers can all free their AK-backed
storage with plain kfree().
Sanitizer builds still use the system allocator. LeakSanitizer does not
reliably trace references stored in mimalloc-managed AK containers, so
static caches and other long-lived roots can look leaked. Pass the old
size into the Rust realloc shim so aligned fallback reallocations can
move posix_memalign-backed blocks safely.
Static builds still need a little linker help. macOS app binaries need
the Rust allocator entry points forced in from liblagom-ak.a, while
static ELF links can pull in identical allocator shim definitions from
multiple Rust staticlibs. Keep the Apple -u flags and allow those
duplicate shim symbols for LibJS and LibRegex links on Linux and BSD.
This allows us to get rid of the annoying Build/.../Lagom directory
and helps to deduplicate a bunch of logic while also drastically
simplifying everything.
This is largely based of off the work done by Andrew Kaster in #5918.
Having this toggle makes much more sense, especially if there will be
more UIs in the future.

Root had identical copy of what was being done in Meta/Lagom
so now we ensure this is still included globally but is
isolated to its own cmake module to make sanitizer
config easier to discover
The implicit default CMAKE_OSX_SYSROOT was a workaround in CMake for
macOS ~10.8. As of CMake 4.x, CMake expects macOS host compilers to have
their own default sysroot detection logic. However, upstream llvm does
not actually do this, only Apple Clang does. To keep supporting homebrew
clang and manually compiled clang from llvm/llvm-project, we need to
set the sysroot explicitly.
The behavior difference and lack of default detection logic in the clang
driver is tracked at https://gitlab.kitware.com/cmake/cmake/-/issues/26863
Explicitly link final targets with OpenSSL to ensure that the vcpkg
version is loaded instead of the system one.
Before this change we would inherit `libcrypto.so` and `libssl.so` from
other dependencies, like Qt, that do not have their RPATH rewritten.
This would cause the loader to prefer the system libraries over the
vcpkg ones causing all sorts of version mismatch issues.
The effectiveness of this change can be verified with
`readelf -d ./bin/Ladybird` showing `libcrypto.so` and `libssl.so` as
direct dependencies, before they would not appear. Additionally, `ldd`
will show `libcrypto.so` and `libssl.so` pointing to the vcpkg builds.
We currently compile the Qt event loop files multiple times, for every
target which wants to use them. This patch moves these to LibWebView as
a central location to avoid this.
Override the vcpkg/scripts/detect_compiler behavior of always pulling
$CC and $CXX at the time that vcpkg install is determined to need called
by forcing $ENV{CXX} and $ENV{CC} to our CMake-determined compiler.
This prevents strange behavior such as running the following:
./Meta/ladybird.sh run
make changes...
ninja -C Build/ladybird
Where the second build step would be run without CC or CXX set in the
environment, causing a total cache miss from vcpkg and a full rebuild.
It also helps prevent full rebuilds when an IDE passes a slightly
different compiler to the build step than ladybird.sh.
This ensures that vcpkg downloads and builds all dependencies for
Android. We add it as a CMAKE_TOOLCHAIN_FILE that then chainloads the
Android NDK's toolchain file, as per the vcpkg documentation.
Also add a vcpkg command to ladybird.sh to ensure that vcpkg is setup,
and use a local binary cache for vcpkg build and install media to
avoid cluttering $XDG_CACHE_HOME.
We will use sqlite3 as a replacement for LibSQL. Using a tried-and-true
database will allow us to avoid maintaining our an incomplete, non-ACID,
and less performant implementation. It also means we do not have to
launch and manage the singleton SQLServer process.
Apart from bumping the toolchain Clang's and port's version, this commit
completely overhauls the way LLVM toolchain is built.
First, it gets rid of a complicated two-stage process of first compiling
clang and compiler-rt builtins and then building libunwind, libc++abi,
and libc++ -- it is possible to create a complete cross-compilation
toolchain in a single CMake invocation with a modern LLVM. Moreover, the
old method was inherently unsupported and subtly broken.
Next, it utilizes full potential of the Stubs "framework". Now we are
even able to compile Clang with -Wl,-z,defs which makes one of the
patches obsolete and the whole installation less error-prone. Note that
it comes at a cost of complicating the bootstrap process on a completely
novel architecture but this hopefully won't happen often.
Lastly, it fixes handling of the -no*lib* family of flags in the
Serenity LLVM driver and correctly uses -nostartfiles in conjunction
with stubs to make necessary CMake configure-time checks succeed.
