[Pkg-erlang-devel] Bug#844593: erlang-wx: WX broken due to "-fno-pie -no-pie" CFLAGS/LDFLAGS

[Johannes Weißl]

Package: erlang-wx
Version: 1:19.1.6+dfsg-1
Severity: grave
Tags: upstream patch
Justification: renders package unusable

The solution of bug #842998 breaks WX:

    1> observer:start().
    {error,{{load_driver,"No driver found"},
            [{wxe_server,start,1,[{file,"wxe_server.erl"},{line,65}]},
             {wx,new,1,[{file,"wx.erl"},{line,115}]},
             {observer_wx,init,1,[{file,"observer_wx.erl"},{line,104}]},
             {wx_object,init_it,6,[{file,"wx_object.erl"},{line,355}]},
             {proc_lib,init_p_do_apply,3,
                       [{file,"proc_lib.erl"},{line,247}]}]}}

    =ERROR REPORT==== 17-Nov-2016::10:12:15 ===
    ERROR: Could not find 'wxe_driver.so' in: /usr/lib/erlang/lib/wx-1.7.1/priv

What works is to remove "-fno-pie -no-pie" from CFLAGS and LDFLAGS in
debian/rules and to apply the following two upstream patches:

- https://github.com/erlang/otp/commit/5aa13e16ae81050509fceaf603650fc8594af7ec.patch
- https://github.com/erlang/otp/commit/edfa3b87542687baa2530a41241eb83d9afda1fb.patch

(both are necessary).
