[Pkg-tcltk-devel] Bug#897429: ppc64el: Shared Object not available in the platform

[Breno Leitao]

Source: tclreadline
Version: 2.1.0-15
Severity: critical
Tags: patch

Dear maintainer,

I just found that this package is not generating the shared object for
ppc64el platform, as showed below:

  dpkg -c tcl-tclreadline_2.1.0-15_ppc64el.deb | grep lib/powerpc64le-linux-gnu
  drwxr-xr-x root/root         0 2016-10-08 05:04 ./usr/lib/powerpc64le-linux-gnu/
  -rw-r--r-- root/root     25340 2016-10-08 05:04 ./usr/lib/powerpc64le-linux-gnu/libtclreadline.a

Looking at the 'configure' process, I see the failure on detecting if
the shared object should be built. This is the build log line and
explains the problem.

  checking whether to build shared libraries... no

I checked against unstable/buster version (2.3) and this problem does
not happen anymore. So, this fix will only need to make Stretch.

The real cause of this problem is realted to the following exemption of
powerpc, which might be removed.

   case "$host_cpu" in
    powerpc*) dynamic_linker=no ;
    *) dynamic_linker='Linux ld.so' ;;


With the patch above, I can see the shared objects being generated:

  dpkg -c tcl-tclreadline_2.1.0-15+deb9u1_ppc64el.deb  | grep \.so
  -rw-r--r-- root/root     67664 2018-05-02 10:05 ./usr/lib/powerpc64le-linux-gnu/libtclreadline-2.1.0.so
  lrwxrwxrwx root/root         0 2018-05-02 10:05 ./usr/lib/powerpc64le-linux-gnu/libtclreadline.so -> libtclreadline-2.1.0.so
