Bug ID: 10974
Summary: libxfcegui4-4.10.0 is broken when built against
libxfce4util-4.11.0 (git) with missing xfce_setenv()
Classification: Xfce
Product: Libxfce4util
Version: Unspecified
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: Medium
Component: General
Assignee: [email protected]

When libxfcegui4-4.10.0 (which is same as git currently) is built against
libxfce4ui-4.11.0 (or git) using CFLAGS="-Wimplicit-function-declaration" you
see this:
libxfcegui4-4.10.0/libxfcegui4/xfce-exec.c:82:5: warning: implicit declaration
of function 'xfce_setenv' [-Wimplicit-function-declaration]
And then, if you try to compile something against that newly built libxfcegui4,
using ld.bfd (the default linker of binutils) using LDFLAGS="-Wl,--as-needed"
as added by some of Xfce's configure.ac's and distribution build scripts.
Let's take xfce4-wmdock-plugin-0.6.0 for example:

</quote>
The compilation is aborted because:
# nm -D /usr/lib/libxfcegui4.so.4.3.0 |grep setenv
U xfce_setenv
"U" as in undefined!
So it seems libxfcegui4 git should be fixed for libxfce4util git. I know
libxfcegui4 is a dead library, but we still have dozen or more plugins that are
unported.
In Gentoo, all of these are at their latest version, and still use libxfcegui4:
http://qa-reports.gentoo.org/output/genrdeps/rindex/xfce-base/libxfcegui4
xfce-extra/xfce4-cellmodem-plugin-0.0.5
xfce-extra/xfce4-dict-0.6.0
xfce-extra/xfce4-gvfs-mount-0.0.4
xfce-extra/xfce4-linelight-plugin-0.1.7
xfce-extra/xfce4-messenger-plugin-0.1.0
xfce-extra/xfce4-modemlights-plugin-0.1.3.99
xfce-extra/xfce4-notes-plugin-1.7.7
xfce-extra/xfce4-playercontrol-plugin-0.3.0
xfce-extra/xfce4-quicklauncher-plugin-1.9.4-r1
xfce-extra/xfce4-radio-plugin-0.5.1
xfce-extra/xfce4-verve-plugin-1.0.0
xfce-extra/xfce4-wmdock-plugin-0.6.0
xfce-extra/xfswitch-plugin-0.0.1-r1
So, would it be possible to get libxfcegui4 fixed in git? I don't care if it's
released or not, but distributions will be asking for it...
Gentoo is at pretty good situation wrt porting from gui4 to 4ui, some other
distributions have double that many unported ones
Thanks!
