emerge--info

Compile wicd, wpa_supplicant (+ssl +gnutls +eap-sim ), wicd-client-kde

run wicd-client-kde, choose WPA/WEP/WPA2 network, check "Use encryption" 

Actual results: no possible encryption types are suggested. No field to type password.

Expected result: Drop-down menu with encryption options are became available, like when you start wicd-gtk

Sounds like an upstream issue. Could you please file a bug upstream and link here back?

link to bug in upstream https://bugs.kde.org/show_bug.cgi?id=297267

Hi KDE Team.  You may want to check out the wicd ebuild where we do the following:

# Need to ensure that generated scripts use Python 2 at run time.

sed -e "s:self.python = '/usr/bin/python':self.python = '/usr/bin/python2':" -i setup.py || die "sed failed"

Cheers, Thomas

@Evgeny Is the bug still valid?

I cant find any python related source files in tarball. So i guess the mentioned problem in upstream bug about active python version is in net-misc/wicd.

comparison of wicd-gtk client and wicd-kde-client under python-3

I cannot see how this is a net-misc/wicd issue, because the wicd gtk client works just fine irrespective of whether python-3 or python-2 is set default.

View the attached screenshot to see what I mean. Here, python-3 is set default. After a restart, wicd-gtk works just fine, but wicd-kde-client does not.

This is a valid bug and should be reopened.

Patch to pass name of python binary to cmake

[Comment 9 MasterPrenium 2012-10-15 15:06:29 UTC]

I had the same problem.

We need to had -DPYTHONBIN=/usr/bin/python2 to cmake options in order to get encryption field working correctly.

I saw someone setting this in CFLAGS, but doesn't work for me.

I attached a small and ugly patch, with this, it works for me, could you try ?


Maybe someone can make a nice patch and add it to the ebuild for the mainstream tree ?

users complaining about this in #gentoo

please double check if this bug is valid

I think this bug needs another look, clearly the wicd-kde code does use python.  It uses the default system "python", which needs to be changed to "python2" if this code is known to be python2-only.  Right?

An user in #gentoo indicated the following patch may have solved the issue (or possibly a wicd upgrade). I can't really test myself, as I don't have a system with both a wifi card and kde.

--- a/wicd-kde/applet/CMakeLists.txt
+++ b/wicd-kde/applet/CMakeLists.txt
@@ -1,5 +1,5 @@
 if (NOT PYTHONBIN)
-    set (PYTHONBIN "python" CACHE STRING "python command")
+    set (PYTHONBIN "python2" CACHE STRING "python command")
 endif (NOT PYTHONBIN)
 configure_file (config-python.h.cmake config-python.h)

Likely it would be possible to set the variable through -D arguments to cmake, which would be better.

[Comment 13 Stephen Bosch 2012-10-15 20:15:21 UTC]

I have tested Erik's patch, and it does indeed resolve the problem.

Can we commit this to a keyworded ebuild?

This patch for the ebuild should make it force python2 as required
