Android: odd entry in lib dir

[ibrown]

Hi, I'm trying to compile ogre latest 1.9 for android using a macosx Lion host.
The compile goes ok, but the sample fails to link because it cannot find the libraries:

Code: Select all

Linking CXX shared module ../../lib/libSampleBrowserDummy.so
Updated project.properties
Updated local.properties
Updated file /Users/ian/Android/Ogre/build/SampleBrowserNDK/proguard-project.txt
It seems that there are sub-projects. If you want to update them
please use the --subprojects parameter.
SharedLibrary  : libOgreSampleBrowser.so
/Users/ian/Android/android-ndk-r8d/toolchains/arm-linux-androideabi-4.6/prebuilt/darwin-x86/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: error: cannot find -lSample_CameraTrack

I looked in build/lib and saw there was a directory called $(PLATFORM_NAME) which seems wrong. In that directory are all the libs. Is anyone else seeing this? Where would I look for clues as to the issue?
A shell log showing what I mean is below:

Can anyone help?

Thanks,

I wonder whether this commit broke android?

https://bitbucket.org/sinbad/ogre/commi ... d6d6ecb35c

is anyone else seeing this issue with the latest 1.9?

[Wolfmanfx]

Compiling it right now

[masterfalcon]

It's entirely possible. I didn't think about the case where you'd be cross compiling for android on os x. i'll check on it too.

[masterfalcon]

Try applying this then reconfiguring with CMake.

I see the same on Windows 8Pro, so I don't think it is anything to do with macosx as the host...

[Wolfmanfx]

Yep same happen on windows too "C:\Development\OGRE\AndroidBuild\lib\$(PLATFORM_NAME)"

[masterfalcon]

Ok, try that patch on windows too. it should work

[Wolfmanfx]

The patch will work inneed (you guys posted during i wrote my post)

[masterfalcon]

If you guys give it a thumbs up I'll commit it ASAP.

[ibrown]

I won't have time to test it tonight, but it looks good from a code reading point of view. Of course whether it sill works with iOS is another question

[Wolfmanfx]

So i rerun the build with the patch included and the linking works again - thumbs up!

[ibrown]

Hi Guys, thanks for the quick response on this issue. I just tried it again on the Mac and it fails in a different way ... I think it is due to the recent GL3 changes though and not the issue above:

Ah, I'm on it. Did you enable the GLES3 support in CMake? If not, reconfigure. Since there is a new option some stuff may need to get filled in for the defines to be set up correctly.

[ibrown]

nope, nothing special in the cake, all defaults. feature summary is like this:

Ok, I see what I missed. I just pushed a change that should fix it for you.

[ibrown]

It doesn't seem to have made any difference I'm afraid. Exact same error message.

Could you check that OGRE_NO_GLES3_SUPPORT is defined to 1 in OgreBuildSettings.h?

yes, it is.

Hmm, I'm not sure why it's trying to include those headers. Just for fun try including OgreBuildSettings.h at the top of OgreGLES2Prerequisites.h to see if that fixes it for now.

[ibrown]

you've got a typo, there are 3 Ps in SUPPORT in the configured header

Oh jeez. Thanks for catching that. I'm getting sloppy.

build works now, thanks!

I looked there. Path with file exists: "....../project_dir/lib/iphonesimulator/Release/libOgreMainStatic.a".
So, I think, problem is in cmake_install.cmake. It can not handle $(PLATFORM_NAME) variable.

Any suggestions?
