Aubio ARMv7 / iOS about aubio

[piem]

yes, with the following command:

./waf clean configure --destdir aubio-arm --with-target-platform ios build install

i just updated the build system to use the 7.0 sdk (see ff75d60).

Maybe is

err: ld: building for MacOSX, but linking against dylib built for iOS Simulator file ?

[luca-bernardi]

Did you manage to fix that? It's seems a that waf isn't able to locate stdlib.h but in my case the header is in /usr/include

[loretoparisi]

After the last update I had

macbookproloreto:aubio loreto$ ./waf clean configure --destdir aubio-arm --with-target-platform ios build install
'clean' finished successfully (0.109s)

The configuration failed
(complete log in /Users/loreto/Projects/AUDIO/aubio/build/config.log)

I have the stdlib.h located at

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/stdlib.h

[loretoparisi]

I was looking at the wscript.

Here it seems to be ok

if Options.platform == 'ios':
DEVROOT="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer"
SDKROOT="%(DEVROOT)s/SDKs/iPhoneOS%(SDKVER)s.sdk" % locals()
ctx.env.CFLAGS += [ '-arch', 'armv7' ]
ctx.env.CFLAGS += [ '-arch', 'armv7s' ]
ctx.env.LINKFLAGS += ['-arch', 'armv7']
ctx.env.LINKFLAGS += ['-arch', 'armv7s']

[luca-bernardi]

Same here. Also, I thinks is worth to add arm64 to the other architectures.

Anyway, I thinks that probably it's easier to create an xcode target for a static library.

[piem]

Hi!

So what exactly isn't working here?

I just updated wscript to fix the build on darwin (macosx), but ios and iosimulator targets are building fine for me.

It might help to run ./waf distclean after a git pull.

[loretoparisi]

So what happens is

macbookproloreto:aubio loreto$ git pull

I confirm the same step and the same output.

[piem]

Hi!

please try again now :)

also, i have uploaded a universal framework for ios to test here:

http://aubio.org/beta/aubio-0.4.0~alpha+0c11dfa.ios_framework.zip

you should be able to just drag and drop it in your XCode ios project.

let me know how it goes!

thanks, piem

[luca-bernardi]

Now it works. I am able to build using waf and also use the provided .framework. Thanks for the help.

[loretoparisi]

The framework is ok. @lukabernardi how did you managed to compile via the waf ?

[luca-bernardi]

@loretoparisi Yes. The only gotcha is that firstly i run

 ./waf configure --with-target-platform iOS

and the the full command for the build otherwise the script complain that isn't configured.

[piem]

the following should now work:

    ./waf distclean
    ./waf configure --with-target-platform ios
    ./waf build
    ./waf install --destdir ./dist-ios

note it's ios, not iOS. you can try with iosimulator too.

cheers, paul

[loretoparisi]

Great guys, it works now. Let's close and roll!
