Success Stories?

[h0tw1r3]

osxcross is pretty much awesome sauce.

What do you think about adding a Wiki page of success stories.

[tpoechtrager]

I also thought about creating a wiki for OSXCross, but I haven't started one yet, it's all a lot of work as a one-man project maintainer...

Any help would be more than welcome!

a Wiki page of success stories.

Better not because of: https://github.com/tpoechtrager/osxcross/issues/4

So far Godot builds nicely with it, and it's a pretty complex codebase.

[purpleorangegames]

Hey reduz, is there a tutorial on how to use osxcross with godot?

[reduz]

it just works, install it as the page describes and then use the environment var OSXCROSS_ROOT to wherever you did the osxcross git checkout

We didn't have much success with iOS though, not quite sure I understand how to do it.. so help is appreciated.

That's an amazing response @tpoechtrager. Thank you very much for the detailed instructions :)

[ghost]

Hey @tpoechtrager, I really like your work! It's saved me loads of time :) Just thought I'd post this snippet for anyone who might have lost their symlinks in the SDK:

SDK=~/deps/SDK/MacOSX10.9.sdk
FRAMEWORKS=`find ${SDK} -name "*.framework" -type d`
for FRAMEWORK in $FRAMEWORKS; do
  if [ -d "${FRAMEWORK}/Headers" ]; then
    [ -d "${FRAMEWORK}/Versions/A/Headers" ] && ln -s ${FRAMEWORK}/Versions/A/Headers/* ${FRAMEWORK}/Headers/ 2> /dev/null
    [ -d "${FRAMEWORK}/Versions/B/Headers" ] && ln -s ${FRAMEWORK}/Versions/B/Headers/* ${FRAMEWORK}/Headers/ 2> /dev/null
    [ -d "${FRAMEWORK}/Versions/C/Headers" ] && ln -s ${FRAMEWORK}/Versions/C/Headers/* ${FRAMEWORK}/Headers/ 2> /dev/null
  fi
  if [ -d "${FRAMEWORK}/Frameworks" ]; then
    [ -d "${FRAMEWORK}/Versions/A/Frameworks" ] && ln -s ${FRAMEWORK}/Versions/A/Frameworks/* ${FRAMEWORK}/Frameworks/ 2> /dev/null
    [ -d "${FRAMEWORK}/Versions/B/Frameworks" ] && ln -s ${FRAMEWORK}/Versions/B/Frameworks/* ${FRAMEWORK}/Frameworks/ 2> /dev/null
    [ -d "${FRAMEWORK}/Versions/C/Frameworks" ] && ln -s ${FRAMEWORK}/Versions/C/Frameworks/* ${FRAMEWORK}/Frameworks/ 2> /dev/null
  fi
done

I finally got Qt 5.5 with qtwebkit to compile :) Thanks so much for all the effort @tpoechtrager :+1: It's nice being able to compile for linux, windows and osx from a single ubuntu machine :) We are probably moving over to travis-ci, but it was a really fun challenge getting all our dependencies to compile for mac from linux :P

[tpoechtrager]

@SDCDev @rynomster Glad to hear that! :-)

[fdelapena]

Thank you @tpoechtrager for the iOS explanation, it works like a charm!

Here is how we are cross building our apps with toolchains made with osxcross and cctools-port. Maybe you find useful which lines we are using. We are building static libraries such SDL2, libicu, expat, freetype, etc. Those prefixed with a "+" are the script commands:

OS X: https://ci.easyrpg.org/job/osx-toolchain/lastSuccessfulBuild/consoleFull https://ci.easyrpg.org/job/liblcf-osx/lastSuccessfulBuild/consoleFull https://ci.easyrpg.org/job/player-osx/lastSuccessfulBuild/consoleFull

iOS: https://ci.easyrpg.org/job/ios-toolchain/lastSuccessfulBuild/consoleFull https://ci.easyrpg.org/job/liblcf-ios/lastSuccessfulBuild/consoleFull https://ci.easyrpg.org/job/player-ios/lastSuccessfulBuild/consoleFull

iOS result demo video

Just a note for building latest SDL2 for iOS: you need to enable ARC (by passing -fobjc-arc, check the ios-toolchain link above) and clang will need to find an additional library (/usr/lib/llvm-3.5/lib/arc/libarclite_iphoneos.a in our debian host case) for the compiler test, which can be found in one of SDK folder. When the build fails with "cannot create executables", check the file SDL2 config.log to see which is the right path missing in your distro. This file is available when unpacking the SDK in Xcode/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphoneos.a. If you are using an older Xcode version, there is some related reference about this.

Hope this helps :+1:.

Hi there. I was glad to com across this thread, and across your work tpoechtrager ;-) I think that I may find some help so I ask my question here : I cross build llvm+clang for iOS8.4 (arm64) successfully, see here :

http://stackoverflow.com/questions/32808144/how-to-cross-compile-clang-llvm-3-7-0-for-ios8-x-on-ipad-mini-3

(i'm using XCode 7 to which I re-added the 8.4 sdk) for the whole story and now I have a linking "problem" --> I don't have any linker... ;-) So I naturally started to look for methods to build binutils for iOS8.4 (arm64), without much success, and came across your cctools port. I would like to build cctools for iOS8.4 (arm64), how could I do it ?

Thx in advance,

MEF

PS : sorry for this way of contacting you, btw... (did not have any other)

[tpoechtrager]

@MisesEnForce I answered your questions on StackOverflow.

@tpoechtrager Excellent work!

[Wohlstand]

@rynomster, can you tell me how you built Qt 5.5?

[tpoechtrager]

@fxfactorial: Thanks!

[rynomster]

@Wohlstand if you need ssl support, you'll need to first compile openssl. If you need to compile qtwebkit you need flex and icu, and to compile icu. I made a custom spec called macx-clang-linux. I've automated the process using gitian on lxc, you can checkout https://github.com/shadowproject/shadow/blob/master/contrib/gitian-descriptors/qt-osx.yml If you need help understanding it, let me know. Sorry about the late reply, I only saw my mail now.

[fxfactorial]

@tpoechtrager

I took this, built on it, and wrapped it up in nixpkgs !

Now all you need to do is:

nix-env -i clang ios-cross-compile

(some instructions will come up for the SDK, which of course I can't resdistribute) and you'll have the compiler installed.

[cprevallet]

@tpoechtrager

Thanks so much for this! It worked like a charm for my needs.

[sparker256]

@tpoechtrager

I have been looking for this solution for some time and glad it was brought to my attention. Xsaitekpanels (github.com/sparker256/xsaitekpanels) is now using osxcross so I can build the complete multiplatform package on my Ubuntu 16.04 LTS machine.

Thank you Bill

[rraallvv]

@rynomster did you enabled macOS builds on Linux for travis? Are there any issues regarding Apple SDK's license agreement?

[iTrooz]

New success story: we used osxcross to build ImHex for MacOS arm64 (M1) The package isn't properly signed for now, but it's probably an error with our build system rather than osxcross

For anyone interested: CI ImHex build Dockerfile oscross dockerfile available as a package here

[woct0rdho]

Just want to share that we've built a game made with Unity using xcbuild and osxcross, because I'm too lazy to copy it to a Mac

I've written a blog in Chinese, and I think Google Translate works well there: https://zhuanlan.zhihu.com/p/686139717

Most of the runtime is implemented by Unity and IL2CPP, and the iOS UI part is only a simplest full screen canvas, so it's relatively easy to use open source tools to finish the remaining building procedure
