Can you report a test case? It works for me here, I think.

For me, even the following sequence leads to the problem:

1) remove ~/.cache/kdevduchain (just in case)
2) launch kdevelop. create new session. create new project from template "Standard/terminal"
3) add run target. Remove "Build" depenedencies from the launch target configuration
4) build project
5) try to launch. It fails


Maybe you can point me where (in sources) debugging might be started?

Hm... Now even if I specify the executable manually, KDevelop can not start it with the same message.

When targets are listed in build dependencies, KDevelop tries to build and install them, even when I select just "Build"

If I disable "Plasmoid launcher plugin", KDevelop crashes when I try to launch native application.

If "Plasmoid launcher" is enabled, in NativeAppJob::NativeAppJob() I see that executable, returned by iface->executable() is indeed empty. envgrp there is empty also.

Do these facts and my previous comment mean that plasmoid launcher is selected instead of native launcher?

And, finally, if I remove /usr/share/kde4/services/kdevexecuteplasmoid.desktop file, native launch works

Git commit 91cd040180ee526658455e6324e365e1be63acfe by Aleix Pol, on behalf of Andras Mantia.

Pushed by apol into branch '1.5'.

Enforce picking up of the right plugin, otherwise we got two (plasmoid launcher and application) and the first one was used (plasmoid launcher) for native apps as well. That resulted in broken build & execution of the project.
