"cannot invoke compiler!" on ios toolchain, and some questions about osxcross

[tpoechtrager]

Hi. I'm following the instructions here (provided by tpoechtrager) to compile Godot for iOS on our build server: #45 (comment) . After running "build.sh" for the toolchain, I get "cannot invoke compiler!" when I run bin/arm-apple-darwin11-clang++. What is it supposed to be running?

Clang must be installed and in PATH.

Also, will there be a different toolchain for each architecture? (on apple's toolchain we use -arch armv7 or -arch arm64 on the same I think). Fat binaries that include arm64 are required to publish on the app store, so that's what we're going for. What is the "root" of each toolchain, that I can pack and put on our build server?

No, you can build fat binaries with the "ios example toolchain" too, just pass the -arch option(s) to the compiler. Copying "target/*" onto the server after running build.sh should be enough.

Ok installing native clang worked, now I get the standard "no input files". Thanks!

So I run build.sh twice in the same place, one with "armv7", another with "arm64", and that should be able to use -arch with armv7 and arm64? or what is the purpose of that last parameter to build.sh?

[tpoechtrager]

You only need to build the toolchain once, the last parameter just sets the default architecture.

arm-apple-darwin11-clang++               # default arch

arm-apple-darwin11-clang++ -arch arm64   # arm64
arm-apple-darwin11-clang++ -arch armv7   # armv7
arm-apple-darwin11-clang++ -arch armv6   # armv6

arm-apple-darwin11-clang++ -arch armv7 -arch arm64  # armv7 and arm64

awesome, thanks

I'm getting this error when I compile with -arch arm64:

"clang: error: invalid arch name '-arch arm64'"

Using -arch armv7 and armv6 both work tho (the armv7 binary runs perfectly on an iphone) Do I need to do something to add arm64?

Thanks!

You need clang >= 3.5 for arm64.

With clang 3.6 I'm able to build with -arch armv7 -arch arm64. In fact, I was able to build Godot for iPhone on my Ubuntu machine.

@vnen: Thanks for letting me know. Does the 64-bit binary work? I haven't had the chance so far to test -arch arm64 properly.

I've been able to compile both architectures (with clang 3.6, thanks for
the tip George), and create the fat binary with arm-apple-darwin11-lipo, it
runs on the iphone 6. My next step is to submit a game to the app store,
see if they approve.
