CMake: iOS SDK not found (Xcode 4.3.3)

[aleroy]

I was attempting to build the latest 1.8 (from the current repo) and ran into an issue with CMake ... it's telling me it couldn't find the iOS SDK. This also prevents the Samples build files from being generated. Here's relevant part of the CMake log:

I built CMake from source myself. I know it works with other iOS projects. This wasn't an issue a few months ago ... but, I had the same issue when I ran the same SDK build script I used to build the binaries I'm using now (the sh script from the wiki article). So, possibly a result of one of the last two Xcode updates (4.3.2 or 4.3.3)?? Any ideas?

Normally, if I saw something like this, I would simply install whatever it wants ... but, in this case, I'm hesitant.

[masterfalcon]

Yes, this is a known issue with CMake 2.8.7 and before. You will need to use their latest trunk code where Xcode 4.3 is now supported. The issue is scheduled to be fixed in 2.8.8

[aleroy]

Thank you for the prompt response. Unfortunately, it does not resolve the issue I am having. As mentioned, I have already built and installed the latest code from the CMake repository. I did so again, just to be sure. I can confirm my CMake build is working with other projects using CMake---successfully generating Xcode 4.3.3 projects with MacOSX as well as iOS targets.

[aleroy]

Still trying to solve this. I'm really not sure why cmake is able to find my iOS SDK for another project (SOCI) but unable to find it for Ogre.

Anyways, I tried some things:

Code: Select all

xcode-select -print-path

/Applications/Xcode.app/Contents/Developer

Code: Select all

cmake -D OGRE_BUILD_PLATFORM_APPLE_IOS=1 -G Xcode ../build

As you can see, this is not the issue reference here: http://www.cmake.org/Bug/view.php?id=12621
But rather that the iOS SDK headers path and IOKit are not found. So, I looked at the CMake cache values:

Over at Apple Developer website, I found:

(http://developer.apple.com/library/ios/ ... works.html)

Each version of the iOS SDK includes a local copy of the dynamic shared libraries that are installed with the system. These copies are installed on your development system so that you can link to them from your Xcode projects. To see the list of libraries for a particular version of iOS, look in <Xcode>/Platforms/iPhoneOS.platform/Developer/SDKs/<iOS_SDK>/usr/lib, where <Xcode> is the path to your Xcode installation directory and <iOS_SDK> is the specific SDK version you are targeting. For example, the shared libraries for the iOS 4.2 SDK would be located in the /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/usr/lib directory, with the corresponding headers in /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/usr/include.

So, I tried setting iOSSDK_INCLUDE_DIR:PATH in the cmake command:

Code: Select all

cmake -D OGRE_BUILD_PLATFORM_APPLE_IOS=1 iOSSDK_INCLUDE_DIR:PATH=/Applications/Xcode.app/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/usr/include -G Xcode ../ogre

Which produced the same output as above.

Building the OgreMain target of the generated OGRE.xcodeproj fails (whether by command-line or Xcode) with errors:

Other things of note

Build Settings (target:OgreMain):
Base SDK = Latest iOS (iOS 5.1)
iOS Deployment Target = iOS 5.1

From "Build Phases": if I add "Link Binary with Libraries" and click the "+" to add a new entry, none of the iOS frameworks/libraries appear in list of choices ... also, the "Other" button isn't there to select a library manually.


Please, I am not a hobbiest playing at making a game for fun. I could really use some help here.

[masterfalcon]

Ok, I think I see your problem. Make sure that you are inside the build folder then your CMake line shouldn't be:

cmake -D OGRE_BUILD_PLATFORM_APPLE_IOS=1 -G Xcode ../build

but instead

cmake -D OGRE_BUILD_PLATFORM_APPLE_IOS=1 -G Xcode ..

[aleroy]

Oh, sorry, that was a typo. I actually have the folders setup as follows:

ogre_src_1.80
|--build
|--ogre

where ogre is the src pulled from the git repo. I'm calling the CMake command from the build folder:

cmake -D OGRE_BUILD_PLATFORM_APPLE_IOS=1 -G Xcode ../ogre

{EDIT: I just tried it with the build folder within the ogre folder (using the command you suggest) and had the same results}

[masterfalcon]

Check here: http://www.ogre3d.org/tikiwiki/Building ... e+-+iPhone. I suspect either a problem with xcode-select or command line tools not being installed.

[aleroy]

I found this: http://code.google.com/p/ios-cmake/

This project provides a simple iOS toolchain file that may be used with CMake to build libraries and setup applications. A couple of sample projects are included.

I'm checking it out now ... to see if, perhaps, it may shed some light on my problem.

...

Check here: http://www.ogre3d.org/tikiwiki/Building ... e+-+iPhone. I suspect either a problem with xcode-select or command line tools not being installed.

I'll look into xcode-select. I know that I have command line tools installed ... but I recall there was once an error during an update (it says [installed] in my preferences->downloads ... but I'll try uninstalling/reinstalling)

[AnotherBrian]

Alright.. I'm at the same place as you now. Getting the same error.

I got past my previous stuck point by using a checkout instead of the release candidate source for 1.8.

[AnotherBrian]

Looks like the cmake scripts are looking for the libraries in the old locations.

[masterfalcon]

Which cmake scripts, which libraries, which locations?

[AnotherBrian]

In ogre/CMake/Packages/FindiOSSDK.cmake, I changed the find_path line to find_path(iOSSDK_INCLUDE_DIR iPhoneOS.platform /Applications/Xcode.app/Contents/Developer/Platforms/)

I think FindIOKit.cmake might need a change as well.

I also had to rename the directories in iOSDependencies from Release and Debug to release and debug.

Currently it looks like my first error is "xcodebuild: error: The directory [user_path_stuff]/ogre/build/iOS does not contain an Xcode project."

Edit:.. ahh.. it's generating an xcode project, but it's not putting it in $BUILD

[masterfalcon]

I think there's something else going on locally with your setup. I just ran the script just fine(with a couple issues for lipo near the end). But otherwise, building is just fine. IOKit will not be searched for if you are configuring for iOS, that's the first red flag.

[AnotherBrian]

Do you still have libraries in /Developer?

[masterfalcon]

No.

I think you may have a messed up CMakeCache.txt in your build/iOS folder. delete the whole thing and start over.

[AnotherBrian]

Ah.. I was wondering how to clear that. Looks like it's getting farther now. Building a lot of things... Not sure if any of my changes were required.. I'll have to start from scratch again once I get it working to see.

Update: Got the template project running in the simulator! Building for the device i get a couple errors about copying InfoPlist.strings and one other thing... Looks like something related to this issue: http://www.ogre3d.org/forums/viewtopic.php?f=2&t=69170

Another update: Got the template app working on the device.. Had to fiddle with the build script some. Still get one error, but it runs.

in "ditto "$PROJECT_DIR/$PROJECT_NAME/media/" "$BUILT_PRODUCTS_DIR/Stereo.app/media/"
The first slash after media is incorrect I believe. Needs to be:
ditto "$PROJECT_DIR/$PROJECT_NAME/media" "$BUILT_PRODUCTS_DIR/Stereo.app/media/"

[aleroy]

In ogre/CMake/Packages/FindiOSSDK.cmake, I changed the find_path line to find_path(iOSSDK_INCLUDE_DIR iPhoneOS.platform /Applications/Xcode.app/Contents/Developer/Platforms/)

That did the trick! Thanks AnotherBrian; thanks masterfalcon.

[Arkiruthis]

In ogre/CMake/Packages/FindiOSSDK.cmake, I changed the find_path line to find_path(iOSSDK_INCLUDE_DIR iPhoneOS.platform /Applications/Xcode.app/Contents/Developer/Platforms/)

That did the trick! Thanks AnotherBrian; thanks masterfalcon.

Thank you! I had exactly the same issue as you guys and this fixed it for me. (building the latest cmake from git didn't seem to fix it for me, but maybe that's not the release candidate)

[Ogrergo]

Had the same problem.
