Linking issues about armnn HOT 11 CLOSED

Hi @phamyphen, please could you try using:

-DCMAKE_SYSTEM_NAME=Android when you run Cmake, not -DCMAKE_SYSTEM_NAME=Linux.

You will need to delete CmakeCache.txt before running Cmake again.

It appears that this could be an error in our documentation.

I did a try by changing DCMAKE_SYSTEM_NAME from Linux to Android. Below is the errors. Do I need some additional changes?

Hi @phamyphen and @lukaszs-appdate

It seems to me that the Android toolchain wasn't created successfully. Could you please try the steps for Downloading the Android NDK and making the toolchain again as mentioned in https://github.com/ARM-software/armnn/blob/master/BuildGuideAndroidNDK.md and see if they are successful.

I hope this solves your problem.

@Surmeh ,

How do you confirm that Android NDK（I am using r17b） was created successfully? I tried it again. Same issues.

BTW, the above compiler setting issues happened only after changing DCMAKE_SYSTEM_NAME from Linux to Android.

Any other suggestions?

Best,

Hi @phamyphen and @lukaszs-appdate,

Try changing
DCMAKE_EXE_LINKER_FLAGS=-pie
to
DCMAKE_EXE_LINKER_FLAGS="-pie -llog"
in your cmake configuration. That should link also against Android's log library. You also will need to delete CMakeCache.txt before running cmake again.

That could be an error in our documentation.

Hi,

After fixing the linker error wrt liblog (using -llog linker flag), I get the following linker error. I'm following the complete build instructions from here, on a Ubuntu 16.04 machine.
Only difference is that I'm using Android NDK r17 with --api 24 for my toolchain. However, I beleive that should be a problem

Could someone let me know what I'm missing here? Seems something going wrong withthe standard c++ libs and/or STL.

from armnn.

This could be due to the ACL docs recommending a different version of stl than ArmNN (#44), if two separated toolchains are used for building ACL and ArmNN.

I'd suggest using a single toolchain for both components, as indicated at https://github.com/ARM-software/armnn/blob/master/BuildGuideAndroidNDK.md#download-the-android-ndk-and-make-a-standalone-toolchain.

from armnn.

@santo4ul, alternatively try building both toolchains with "--stl=libc++" and see if that solves the linker errors (if you need to keep the toolchains separated).

from armnn.

I'm able to fix the above linker error.

Looks like the problem was mixing STL in ACL and ARMNN. ACL recommends "--stl=gnustl", while ARMNN uses "--stl=libc++" for toolchains.

I recompiled ACL using the same toolchain I used for ARMNN (with --stl=libc++) and it helped fixing the linker error. However, I'm not sure what runtime errors would comeup.

I've raised this as a separate issue here

Hope we get a resolution on this.

Hi @santo4ul,

Great to hear you've managed to fix your problem. Please get in touch if you have any more problems.
