Re: [CMake] Packaging dylibs into app bundles

[Harry Mallon]

Hi all,

Fixup_bundle works very well for app bundles and seems to be the way to go! The 
problem I was previously seeing was fixed by setting 
CMAKE_INSTALL_RPATH_USE_LINK_PATH to True. This fills in the rpath on the 
installed executable with enough paths to resolve all the dylibs.

I also added a merge request to cmake to fail more obviously if the file cannot 
be found as in previous message.

My next question is: Is there a way to do a fixup bundle without a bundle?

i.e. I want to fixup (copy required dylibs, fix otool ids and rpaths etc) a 
structure like this:

/usr/local/myapp/bin/myapp
/usr/local/myapp/lib/libA.dylib
/usr/local/myapp/lib/libB.dylib # etc


Is there a sensible way to do this without rewriting a lot of Bundle Utilities?

Best,
Harry

Hi,

I have been messing arounds with fixup_bundle (which seems to be the correct 
function). It worked for a small test case, but only if the dylibs required had 
otool ids of their full path. Ours currently have rpath based ones (e.g. 
@rpath/libcrypto.dylib). So I get a lot of:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/objdump:
 '@rpath/ libcrypto.dylib’: No such file or directory

Hmm, seems like the stuff is there somewhere to make this work…

Best,
Harry

Hi Harry,

I don't know how useful this will be, but the Instant Meshes application 
creates an app bundle that has always worked reliably for me. Looking at the 
code, it doesn't appear like there's much custom stuff going on either. It 
starts here

https://github.com/wjakob/instant-meshes/blob/011fa44ab72037cbc16535090a63ead41963c1e5/CMakeLists.txt#L151

And there's an if APPLE block below that appears to be the core.

Hope that is useful :) I've never actually done this for any of my own projects 
though. And I'm pretty sure them setting the underlying GUI library and TBB to 
be static (as opposed to shared) is skirting around the issue that you are 
trying to solve (dylib stuff)...

Re: [CMake] Packaging dylibs into app bundles

[Michael Jackson]

You need to pass in more paths to the “fixup_bundle()” method. Those paths are 
the paths where the libraries are located so CMake has somewhere else to look 
in case the absolute path is not encoded in the dylib itself. I could point you 
to our project but it is pretty scary in there. We use a custom generated CMake 
script that does a bunch of extra stuff that Qt requires (qt.conf) and stuff 
like that. Does work reliably for use once we got it setup.

 

https://github.com/BlueQuartzSoftware/CMP/tree/develop/OSX_Tools

https://github.com/BlueQuartzSoftware/CMP/blob/develop/OSX_Tools/CompleteBundle.cmake.in

https://github.com/BlueQuartzSoftware/CMP/blob/develop/OSX_Tools/MacOSXBundleInfo.plist.in

 

They probably are not an “exemplar” of how to do things as they were created 
when CMake 3.1 was new so there are probably better ways to get the same thing 
done but this works in our environment. I have a whole separate bash script 
that lets us create a signed .dmg file.
