From: Trevor Woerner <twoerner@gmail.com>

In addition to the .so link add a .so.1 link for the target rootfs.

[Buildroot] [PATCH v3 directfb] directfb: font handling requires libbz2

One of the libraries which is built by directfb, libidirectfbfont_ft2.so,
requires libbz2:

That's not true. Freetype might optionally have bzip2 support, but it
isn't a requirement for directfb.

E.G. I did a basic build here:

./host/usr/bin/i586-linux-readelf -a \
  staging/usr/lib/directfb-1.4-6/interfaces/IDirectFBFont/libidirectfbfont_ft2.so
  | grep NEEDED
 0x00000001 (NEEDED)                     Shared library: [libdirect-1.4.so.6]
 0x00000001 (NEEDED)                     Shared library: [libdirectfb-1.4.so.6]
 0x00000001 (NEEDED)                     Shared library: [libfusion-1.4.so.6]
 0x00000001 (NEEDED)                     Shared library: [libz.so.1]
 0x00000001 (NEEDED)                     Shared library: [libfreetype.so.6]
 0x00000001 (NEEDED)                     Shared library: [libm.so.0]
 0x00000001 (NEEDED)                     Shared library: [libdl.so.0]
 0x00000001 (NEEDED)                     Shared library: [libpthread.so.0]
 0x00000001 (NEEDED)                     Shared library: [libgcc_s.so.1]
 0x00000001 (NEEDED)                     Shared library: [libc.so.0]

So the only thing that should be fixed is to ensure bzip2 is built
before freetype (and zlib as well) if enabled. I'll fix that.

Hi Peter,

Thank you for looking into this for me, but this is rather odd. I
pulled your latest fixes and rebuilt (make clean; make) using the
attached config. I too don't see libbz2 listed when I perform the same
"readelf -a" step as you on the host:

./host/usr/bin/arm-angstrom-linux-gnueabi-readelf -a
staging/usr/lib/directfb-1.4-6/interfaces/IDirectFBFont/libidirectfbfont_ft2.so

 0x00000001 (NEEDED)                     Shared library: [libc.so.6]

But when I run the "df_dok" example on the target it complains (as
I've shown before) that libidirectfbfont_ft2.so requires libbz2:

Did I misunderstand your fix? Do I need to do something explicitly in
my build? (I thought the build would pull in any required libraries
automatically).

Best regards,
    Trevor

PS For testing purposes my target is currently an emulated gumstix
overo device under qemu, if you'd like I could provide instructions to
reproduce my exact target.

Is this with a clean build? You must have bz2 headers/libs somewhere for
freetype to be built with bz2 support.

I just built the qemu_arm_versatile_defconfig config with directfb
enabled and tested it in qemu without any problems.

Thanks for helping me out with this, I see the issue now: my external
toolchain contains the bz2 headers/libs in its sysroot.

Ahh ok. We only really support bare external toolchains.

I see. Since the bzip2 headers and libraries exist in my toolchain's
sysroot my build of freetype includes bz2 support. The bz2 dependency
in the directfb library I cited wasn't due to directfb itself but
rather due to libfreetype (which is one of the listed libraries for
the cited directfb library):

./host/usr/bin/arm-angstrom-linux-gnueabi-readelf -a
target/usr/lib/libfreetype.so.6.8.0 | grep NEEDED
 0x00000001 (NEEDED)                     Shared library: [libz.so.1]
 0x00000001 (NEEDED)                     Shared library: [libbz2.so.1]
 0x00000001 (NEEDED)                     Shared library: [libc.so.6]

In this situation would it be worth investigating some sort of tool to
check the shared libraries in the target filesystem for any missing
dependencies from the toolchain (and include them)? I vaguely recall
there already being such a tool, but can't seem to find/remember what
it is called.

Best regards,
    Trevor
