Hi

I am trying to test the caffe-android-demo app, but it's giving me this error. Any idea what's the root cause for this?

@g1910 Please refer to https://github.com/sh1r0/caffe-android-lib/issues/30#issuecomment-192776929. Thanks.

@g1910, did you get the solution for this error? Stuck on it.

[g1910]

Strange that when I pulled the latest changes to the repo and build the library with my changes in it, it was working fine with no such errors. However, there were other errors which followed. The app is randomly crashing giving no error logs and I suspect it is the native binaries. Can it be due to memory or other related issues?

[sh1r0]

@g1910 @rivaldo4t I guess that libcaffe.so is a soft link to libcaffe.so.1.0.0-rc3 in your cases, right? Could you please provide the information about your build environment (OS, NDK, etc.) and targeted android abi in detail? Thanks.

[rivaldo4t]

I am using Ubuntu 14.04.2 LTS and android-ndk-r10e as specified

[sh1r0]

@rivaldo4t Could you provide your cmake version as well? Since I use Ubuntu 14.04 with android-ndk-r10e and cmake 3.3.2, and everything is fine. Thanks.

[rivaldo4t]

I am using cmake version 2.8.12.2

[sh1r0]

@rivaldo4t I recommend you to upgrade your cmake, as I met some issues when using the old version of cmake before.

[rivaldo4t]

@sh1r0, Thanks for the persistent assistance. I got it to work finally.

The problem was not with any of this. I just recently (after you told me to build caffe-android-lib from dev branch) switched my device to try the build libs on; which was not compatible with the build server. I switched my device back to the compatible one and it worked. Silly, I know. Thanks anyway.

@rivaldo4t :+1: Good to know.
