bzip2: add so.1 link

From: Trevor Woerner <[email protected]>

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

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

$ pwd
/usr/lib/directfb-1.4-6/interfaces/IDirectFBFont
$ /lib/ld-2.9.so --list ./libidirectfbfont_ft2.so

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: [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 | grep NEEDED

 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.

Hi,

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

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.

Bye, Peter Korsgaard

Hi Peter,

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

Best regards,
Trevor

Ahh ok. We only really support bare external toolchains.

Bye, Peter Korsgaard

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
