Compile with xcode

[manishagarwal23]

I’m on macOS and trying to compile ThorVG for lottie support . The Meson build system doesn’t seem to be set up properly for mac. Is there a way to compile it using Xcode 16?

[hermet]

@manishagarwal23 Hello, doesn't useful? https://github.com/thorvg/thorvg.swift

[manishagarwal23]

we dont use swift in our build system . we are pure C++ app

[manishagarwal23]

@hermet is there any script which can generate xcode proj file for thorvg

[tinyjin]

Hello @manishagarwal23
It is not common to integrate Meson-Ninja directly within Xcode; instead, the typical approach is to perform build tasks via the terminal. If necessary, Xcode can be configured with an external build system or set up to run terminal build commands through scripts.

1. Setup meson build directory backed by xcode

meson setup build -Dexamples=true -Dloaders="all" -Dlog="true" -Dsavers="all"  --backend=xcode

2. Open generated xcode proj

3. Choose specific example you want

4. Click run button to show example

If there's anything that I can help for you, feel free to comment any time :)

i get following error on command line

`user@mac-user1 thorvg % rm -rf build
meson setup build -Dexamples=true -Dloaders=all -Dlog=true -Dsavers=all --backend=xcode

@tinyjin @hermet kindly guide

[hermet]

@manishagarwal23 Please try this:

Save the following to native.txt

[host_machine]
system = 'darwin'
cpu_family = 'aarch64'
cpu = 'apple-m1' # or just 'aarch64'
endian = 'little'

$meson setup build --native-file native.txt --backend=xcode -Dexamples=true -Dloaders=all -Dlog=true -Dsavers=all

[manishagarwal23]

at my collegues machine (as my machine is giving different issues )

@manishagarwal23 That machine looks to be x86 machine. This case shouldn't use native.txt that @hermet shared.

[hermet]

If it does, you can try with x86_64 but your machine is obviously aarch64. Whatever, fine if any solution works for you.

[tinyjin]

@manishagarwal23 Hello, there seem to be issue with latest meson version in use of xcode backend.

Please downgrade meson version less than v1.8.1 and try again. Note I am using meson v1.6.0. In my machine, it works well with your meson command. I'm attaching my setup log, hope it helps.

unfortunately this too is not working .

Even if we are able to create xcode proj will it be supported in future too as your output says

i have decided to use meson for building locally. so we can close this
