[Bug 1571684] Re: libisoburn fails to build on powerpc

[Thomas Schmitt]

Hi,

i downloaded libisoburn_1.4.2-4ubuntu1.debian.tar.xz and now look
at debian/patches/build-system.patch .

----------------------------------------------------------------

What is the motivation for removing "--silent" from libtool ?

----------------------------------------------------------------

Is it really correct to leave the experiment

     LDFLAGS="$LDFLAGS -Wl,--version-script=libisoburn/libisoburn.ver"
     AC_TRY_LINK([#include <stdio.h>], [printf("Hello\n");],
                 [vers_libs_test="yes"], [vers_libs_test="no"])

based on production of a binary rather than a shared library ?
(Not that i already knew how to test for library link success.)

----------------------------------------------------------------

Why did the minimal test run of xorriso succeed on Debian buildd
about 6 weeks ago ?

https://buildd.debian.org/status/fetch.php?pkg=libisoburn&arch=powerpc&ver=1.4.2-4&stamp=1456745193

Older toolchain ?

----------------------------------------------------------------

The same gesture about --version-script is in libburn/acinclude.m4 .

The binary cdrskin is in about the same relation to libburn, as
xorriso is to libisoburn.

----------------------------------------------------------------

Have a nice day :)

Thomas
