This is our first client of the new JSON GUI declaration thingy.
The skeleton of the TextEditor app GUI is now declared separately from
the C++ logic, and we use the Core::Object::name() of widgets to locate
them once they have been instantiated by the GUI builder.
I know, the tags don't actually matter. However, clang warns by default,
and instead of disabling the warning for clang I'd rather enable the warning
for gcc.
Concludes #3096.
Phew! From here on, build system and CI will ensure that all new code
defines compilation-unit-only code as 'static', and that dead code can
be found more easily. Also, this style encourages type checking
by suggesting that you put a proper declaration in a shared header.
It looks like PR #2986 mistakenly removed this from both the
Clang and GCC CXX_FLAGS, when the intention seems to have been
to only disable it for Clang.
Useful for sanitizer fuzzer builds.
clang doesn't have a -fconcepts switch (I'm guessing it just enables
concepts automatically with -std=c++2a, but I haven't checked),
and at least the version on my system doesn't understand
-Wno-deprecated-move, so pass these two flags only to gcc.
In return, disable -Woverloaded-virtual which fires in many places.
The preceding commits fixed the handful of -Wunused-private-field
warnings that clang emitted.
After running a build command, make by default stat()s the command's
output, and if it wasn't touched, then it cancels all build steps
that were scheduled only because this command was expected to change
the output.
Ninja has the same feature, but it's opt-in behind the per-command
"restat = 1" setting. However, CMake enables it by default for all
custom commands.
Use Meta/write-only-on-difference.sh to write the output to a temporary
file, and then copy the temporary file only to the final location if the
contents of the output have changed since last time.
write-only-on-difference.sh automatically creates the output's parent
directory, so stop doing that in CMake.
Reduces the number of build steps that run after touching a file
in LibCore from 522 to 312.
Since we now no longer trigger the CMake special case "If COMMAND
specifies an executable target name (created by the add_executable()
command), it will automatically be replaced by the location of the
executable created at build time", we now need to use qualified paths to
the generators.
Somewhat related to #2877.
Seems like we can build without these two flags now:
-Wno-sized-deallocation
-fno-sized-deallocation
I don't remember why they were needed in the first place.
This allows us to look up source file/line information from addresses
without bloating the build too much. It could probably be made smaller
with some tricks.
I tried setting it to Release, then noticed that it didn't build
due to gcc's optimizer-level dependent warnings and -Werror, then
started fixing the warnings for a bit (all false positives),
then looked at the global CMakeLists.txt and realized that the
default build is aleady using compiler optimizations. It looks like
people aren't supposed to change this, so make that explicit to
be friendly to people familiar with cmake but new to serenity.
The SDL port failed to build because the CMake toolchain filed pointed
to the old root. Now the toolchain file assumes that the Root is in
Build/Root.
Additionally, the AK/ and Kernel/ headers need to be installed in the
root too.
Make sure that userspace is always referencing "system" headers in a way
that would build on target :). This means removing the explicit
include_directories of Libraries/LibC in favor of having it export its
headers as SYSTEM. Also remove a redundant include_directories of
Libraries in the 'serenity build' part of the build script. It's already
set at the top.
This causes issues for the Kernel, and for crt0.o. These special cases
are handled individually.
This stopped working quite some time ago due to Clang losing track of
typestates for some reason and everything becoming "unknown".
Since we're primarily using GCC anyway, it doesn't seem worth it to try
and maintain this non-working experiment for a secondary compiler.
Also it doesn't look like the Clang team is actively maintaining this
flag anyway. So good-bye, -Wconsumed. :/
