QT5 Android不打包版本化SharedObject

Question

I'm having a problem with QT5 and Android. I am trying to use a cross-build of libpurple (thanks GoogleSummerOfCode), but it is not packing it to the apk and Java throws

E/AndroidRuntime( 1496): java.lang.UnsatisfiedLinkError: Cannot load library: link_image[1937]: 1725 could not load needed library 'libpurple.so.20' for 'libSimpleChat.so' (load_library[1092]: Library 'libpurple.so.20' not found)

The libpurple.so.20 is a symlink to libpurple.so.20.0 , renaming does not change anything, if I copy this link in the android lib folder it is ignored (only .so libs are packaged). Even if i rename it to libpurple.so , it does not work because libpurple.so.20 seems to be hardcoded in a binary.

I have similar problem and solved by re-compiling shared library with non-versioned soname.

Check the soname of the shared library:

$objdump -x libpurple.so | g 'SONAME'

You should see something like:

SONAME    libpurple.so.20

Rebuild library and give a non-versioned soname:

arm-linux-androideabi-gcc -shared -fPIC .... \
    -Wl,-soname,libpurple.so -o libpurple.so

Now the shared library should have a non-versioned soname.

$objdump -x libpurple.so | g 'SONAME'
    SONAME    libpurple.so

When you link this shared library with your own library, it will use non-versioned library name.

$objdump -x libSimpleChat.so | g 'NEED'
    NEEDED    libpurple.so
