[DEPRECATED] Experimental iOS port (LÖVE 0.9.2)

[slime]

I use a VM with XCode 3.2.6 on MacOSX 10.6.8.

It requires Xcode 4.3 and Mac OS 10.7+ or so to build, I think. Mac OS 10.9 is free, so you might be able to upgrade directly to that via the Mac App Store and get Xcode 5 too.

WOW, just WOW!

I'm going to test it ASAP.

One workflow enhancer would be to create a "player" version of the runtime that can get a .love file through wi-fi, that way you can cut the xcode part and also have windows/linux users develop for it (at least until they need to publish. Apple does not allow for that in the store)

Once everything works, you can easily create a fused version of the game for inclusion in the App Store.

Way to go!

Hm sadly not possible to update the vm with mac 10.9. The installation breaks my VM :-/. I need a mac .

I have a mac if you need me to test something.

I would assume so, since he said "you" when referring to me.

Only who can create an iOS version of Löve?

You have pressed "you" referring to "me". That is incorrect.

The correct answer is "you".

Mom, can we play outside? You know, away from the bear?


Keep it up! My hope is one day Löve can be on the iOS App Store with the ability to sync .love files right to the device and play them right on the iPad and iPhone with full touch API. (Alternatively, I would consider Jailbreaking my iPad when a full featured iOS Löve is available if not on the App Store.)

Someday..

Far in the future..

But hopefully not too far.

I get an error when I try to build the project:

Code: Select all

ld: warning: directory not found for option '-L/Users/alex/Documents/hg/love-experiments/platform/ios/libraries/SDL'
ld: warning: directory not found for option '-L/Users/alex/Documents/hg/love-experiments/platform/ios/libraries/lua'
ld: library not found for -lSDL2
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Built on OS X 10.9 with the Xcode 5.0.1 (I believe, it's the latest Xcode). The include and the libraries folder are inside the iOS folder.

EDIT:
And whenever I try to debug without building Xcode crashes.

Thanks, it looks like I accidentally made some paths absolute instead of relative.

[Ranguna259]

How would I change the paths ?
EDIT: Changed them, I had to go to: Build Settings - Search Paths - And changed Library Search Paths

Hi !

I just compiled this iOS port, and I'd like to share some modifications that I have to do or that you can do to simplify the configuration, mostly on the XCode project.
I build with Xcode 5.0.2 on OSX 10.9 .

* Replacing absolute path by relative path (or $(SRCROOT)/"the_relative_path") to find headers and libraries.
* Maybe check in /usr/local/include/"the_lib" for Header search path since it's usually the default destination of third-libraries installation (with makefile configuration). It can avoid to manually copy include directories.
* Add header guards for libraries/luasocket/libluasocket/lua.h (and maybe rename this file to avoid confusion)
* I didn't checked why, but I had to remove

Code: Select all

extern "C" { // Also called from luasocket
  int luax_typerror(lua_State *L, int narg, const char *tname);
}

from common/runtime.h, line 389

Boring pedantic mode :
* Replace "SDL" name/mentions to "SDL2" and maybe "lua" to "lua5.2" to avoid confusion (I still work with projects using SDL1.2 and lua5.1 ).
* Maybe replace all #include <lua.h> by #include "lua.h" for consistency since these libraries may not be copied in standard path (I don't know if there is default or standard path for iOS libraries) or the opposite since Xcode Header Path seems to work, or if you'll use the /usr/local/include/ path, the point is to use the same coding style :p
* I've got some warnings (unused variables and implicit cast), nothing grave

Thank you again for your work

I get an error when I try to build the project:

Fixed.

* Add header guards for libraries/luasocket/libluasocket/lua.h

Done.

* Replace "SDL" name/mentions to "SDL2" and maybe "lua" to "lua5.2" to avoid confusion (I still work with projects using SDL1.2 and lua5.1 ).

Well, LÖVE currently uses LuaJIT (or just Lua 5.1 in the iOS port for now, since I haven't built LuaJIT for iOS yet.)

* Maybe replace all #include <lua.h> by #include "lua.h" for consistency since these libraries may not be copied in standard path (I don't know if there is default or standard path for iOS libraries) or the opposite since Xcode Header Path seems to work, or if you'll use the /usr/local/include/ path, the point is to use the same coding style :p

The "lua.h" is only in the luasocket code (which we try not to modify if we don't have to.) In LÖVE's own code, everything compiled in src/ is #included with quotes, and external libraries are #included with angle-brackets. The #include "lua.h" in the luasocket code also has the benefit of making it a bit more clear that it's #including the local lua.h instead of the external one.

* I've got some warnings (unused variables and implicit cast), nothing grave

I fixed a couple of the warnings, but some of them are from libraries which I can't fix.
