[teamblubee]

When trying to compile godot for android from a mac, mac creates .dylib files that break when you try to load the android app.

I am researching to see how I can create a static library on mac but any additional help would be appreciated as well.

[reduz]

ah i think i know the problem...

open platform/android/detect.py

you will see an if:

if env['PLATFORM'] == 'win32':

import methods
env.Tool('gcc')
env['SPAWN'] = methods.win32_spawn
env['SHLIBSUFFIX'] = '.so'

you should add below, i think the following:

if env['PLATFORM'] == 'check which one is for the mac´ :

env['SHLIBSUFFIX'] = '.so'

and it will work

does it load on android if you rename it to .so?

Updating the code in detect.py the filename comes out as .so but still getting crash on android.

Brother:bin blubee$ otool -L libgodot.android.opt.debug.so
libgodot.android.opt.debug.so: is not an object file

[edit]
Seems the xcode gcc just doesn't support static libraries, I've read some reports that you can use the homebrew or macports gcc to build and that does support making .so files.
I will install that later and give it a shot.

[vkbsb]

If you compile for android , rename the .dynlib to .so and use it. This works i've tested this.

[akien-mga]

What's the status on this issue? There seems to be a need to enforce ".so" extension (for all platforms I guess?), but is it all that is needed to solve this?

[akien-mga]

For the official android templates for 2.0.1, we had them built on OSX as .dylib files, and indeed renaming them to .so before generating the apk on Linux seemed to do the trick.

So I guess the fix is just what @reduz mentioned above and what @vkbsb confirmed.
