ANE - Xcode 7 and .tbd

[Aymeric-]

Hey,

I'm updating an ANE to the latest SDK change. For this new version, I need to add a new lib: libxml2.dylib

So in my platform-ios.xml I've:

<linkerOptions> <option>–lxml2</option> </linkerOptions>

I can compile the ANE, but when exporting on my iPhone I got:
Compilation failed while executing : ld64
Packaging output:
ld: file not found: –lxml2
ld: file not found: –lxml2

It seems the .dylib is no more available through Xcode 7 (El Captain) too, in favor of .tbd files. So how do we update our build file for this new format?

I tried to copy/paste the libxml2.dylib at several places (not sure if the final location changed with El Captain) but without success, still the same issue.

Any ideas?

In my ANE, I only use one .dylib, and my syntax is different:

<option>-weak_library /usr/lib/libsqlite3.dylib</option>

As a caveat, I'm not using Xcode 7, and I'm still on AIR SDK 16, so this may not help you.

Thanks for your answer. Well, if I do that, no error when compiling the ANE, but for the IPA:

Packaging failed!

Packaging error message:

Compilation failed while executing : ld64

Packaging output:

ld: warning: ignoring file /usr/lib/libxml2.dylib, missing required architecture armv7 in file /usr/lib/libxml2.dylib (2 slices)

sounds like it's missing the dylib at ipa compile time. Are you pointing flash builder to the location of the iOS SDK you're using?

Well, I'm using FDT. And at the moment, if I don't specify SDK, I don't know where it is looking for.

If I specify with this one: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.0.sdk I got:

Packaging failed!

Packaging error message:

Compilation failed while executing : ld64

Packaging output:

Warning: The path to platform sdk should end with iPhoneOSx.x or iPhoneSimulatorx.x format to avoid any unintended behavior.

ld: library not found for -lgcc_s.1

ld: library not found for -lSystem.B

Also, if I try to compile my IPA on windows I also get an ld: file not found: –lxml2

Everything seems related to El Captain 😕

[kheftel]

ugh. Sorry, I don't have experience with FDT or El Capitan. I'm still on Yosemite and Xcode 6.x . Wish I could be of more help!

Ok, I'd luck to give a try on an Yosemite Mac with AIR 19 and in fact I've the same problem. So it's not related to Xcode 7 and El Captain (which is good to know). For whatever reason I can't success to include the libxml2. I can compile the ANE, but I always get an error for the IPA whatever I tried.

[kheftel]

what is a .tbd file?
