Broken symlinks in the Example project file #13

Open spixi opened 7 years ago

spixi commented 7 years ago

The example project file contains broken symlinks

I extracted the example project to

/home/mari/Dokumente/Unreal Projects

but it contains broken files, e. g.

/home/mari/Dokumente/Unreal Projects/AugmentedUnrealityEx/Plugins/AugmentedUnreality/Binaries/Linux/libopencv_core.so

is a binary file with the content

Somehow, the packaging process went wrong as this is not a symlink.

So, this should fix the issue and just recover the symlinks.

find -name \*so.\*|sed 's/\(.*\.so\)\.\(.*\)/rm \1;ln -s \0 \1/g'|bash

And oh, I forgot this: mv libc++.so libc++.so.1 mv libc++abi.so libc++abi.so.1

And there are also some missing libraries:

[2017.10.22-00.04.13:966][ 0]LogLinux: Warning: dlopen failed: libopencv_ml.so.3.2: cannot open shared object file: No such file or directory [2017.10.22-00.04.13:966][ 0]LogModuleManager: Warning: ModuleManager: Unable to load module '/home/mari/Dokumente/Unreal Projects/AugmentedUnrealityEx/Plugins/AugmentedUnreality/Binaries/Linux/libUE4Editor-AugmentedUnreality.so' because the file couldn't be loaded by the OS.

I built opencv 3.2 myself now and use it instead of the bundled libraries.
