I did a simple ./Meta/ladybird.sh run ladybird

[shlyakpavel]

AppleClang 15

I guess that's the reason

[alex4o]

I need a newer/older version?

[shlyakpavel]

@alex4o you need a newer version

[alex4o]

Oh thank you, I will revisit this when I update my mac

[alex4o]

You can close this issue then

[rmg-x]

You can view the build instructions/requirements here: BuildInstructionsLadybird.md

Qt6 development packages, nasm, additional build tools, and a C++23 capable compiler like g++-13 or clang-17 are required.

CMake 3.25 or newer must be available in $PATH.

[ADKaster]

This requirement for Xcode 16 is kind of new. I'll need to document it or work around older apple clang

[circl-lastname]

You can close this issue then

If this is resolved then you can close it manually

I have AppleClang 16 installed and I'm still running into issues building on macos. Not quite sure what I might be missing?

$ clang --version
Apple clang version 16.0.0 (clang-1600.0.26.4)
Target: arm64-apple-darwin24.1.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

$ cmake --version
cmake version 3.31.1

build command: ./Meta/ladybird.sh run

build error:

-- Building libvpx for Release
CMake Error at scripts/cmake/vcpkg_execute_required_process.cmake:127 (message):
    Command failed: /bin/bash --noprofile --norc -c "make -j9"

even if I run it with clang from brew I get the same error.

$ $(brew --prefix llvm)/bin/clang --version

[ADKaster]

Apple clang 16 from Xcode 16 is not too old. This seems to be a command line tools issue, someone else mentioned it in discord yesterday.

Presumably installing full Xcode.app will resolve the issue? Though we should figure out why just using the command line tools messes things up.

[shlyakpavel]

@ADKaster yesterday I learned that Qt requires Xcode standalone app to build Qt apps...

[13bdotdev]

@ADKaster thanks for the reply. I got help in the discord build channel. Looks like I needed to just rm my Build directory and start over. I'm guessing because I had tried to build initially but with incorrect versions of things, so once I updated everything it still had stuff cached. It's currently building now still, but taking awhile on my m1 macbook air.

[tristonarmstrong]

Can confirm it builds without issue on Mac (M1 Pro), first try, after following directions.

(unimportant side note): Does take a while. Took a little longer than terminal starwars, for reference.

(side comment): Wild its so alpha, its mind-blowing. In todays age where we expect a browser to behave a certain way, its strange to see a browser that doesn't, with a simple html page like Klectr.dev. Kind of humbling, to say the least. Feels.... good

[zhangzhuang15]

I have this issue too, and I take 2 steps to build successfully. Before list these steps, take a look at my environment:

1. M3 Pro MacBook Pro 16, 18GB mem, 512GB disk, 6 performance 6 efficiency cpu cores
2. clang 19.1.5, clang++ 19.1.5
3. cc 15.0.0 (just execute cc -v in my terminal)
4. macOS 14.3.1

Here 2 steps:

1. remove Build directory
2. execute CC=$(brew --prefix llvm)/bin/clang CXX=$(brew --prefix llvm)/bin/clang++ ./Meta/ladybird.sh run

When it successes, you can see Build/release/bin/Ladybird.app. Don't close your terminal, click Ladybird.app, there will be a window, you can type any url to take a test. But it seems that there are some unimplements, when I visit an url, terminal gives me some outputs which state that 1954925.446 WebContent(5982): FIXME: Unimplemented IDL interface: 'HTMLElementPrototype.showPopover'. We have made a big progress yet.
