Re: [Xen-devel] [PATCH 3 of 5] blktap2: fix vhd compilation under uclibc

[Roger Pau Monnà <roger.pau@xxxxxxxxxxxxx>]

Hello,

I've added -liconv to blktap2/vhd/lib, and succesfully compiled and
linked the library. The output from ldd libvhd.so shows:

checking sub-depends for '/lib/libuuid.so.1'
checking sub-depends for '/usr/lib/libiconv.so.2'
checking sub-depends for '/lib/libc.so.0.9.32'
checking sub-depends for '/lib/ld64-uClibc.so.0.9.32'
        libuuid.so.1 => /lib/libuuid.so.1 (0x00000000)
        libiconv.so.2 => /usr/lib/libiconv.so.2 (0x00000000)
        libc.so.0.9.32 => /lib/libc.so.0.9.32 (0x00000000)
        ld64-uClibc.so.0.9.32 => /lib/ld64-uClibc.so.0.9.32 (0x00000000)
        not a dynamic executable

Then I've compiled and linked vhd tools (vhd-util and vhd-update)
without -liconv, since vhd tools doesn't use any iconv functions. They
compile fine, but when I try to execute them I get the following
error:

vhd-util: symbol 'libiconv_open': can't resolve symbol

If I do a ldd of vhd-util:

        libvhd.so.1.0 => /usr/lib/libvhd.so.1.0 (0x7699efaf4000)
        libc.so.0.9.32 => /lib/libc.so.0.9.32 (0x7699ef88c000)
        libuuid.so.1 => /lib/libuuid.so.1 (0x7699ef689000)
        ld64-uClibc.so.0.9.32 => /lib/ld64-uClibc.so.0.9.32 (0x7699efd10000)

How come libiconv is not linked to the application if libvhd is? And
what's most strange, why is the link to libuuid keep, but not the one
to libiconv?

Thanks, Roger.
