If gtk isn't in your USE variable it won't build nmapfe. Try recompiling nmap as shown below and see if you still have the same problem, USE="gtk" emerge nmap leroutier@gmail.com 2004-09-01 11:20:36 0000 hum, either you misread what i wrote, or i wrote it badly the nmapfe executable exists and is in an accessible path -rwxr-xr-x 1 root root 82196 sep 1 19:01 /usr/bin/nmapfe i used +gtk & +gnome to compile it nmapfe launched from terminal works nmapfe launched from gnome 2.6 menu won't, but would display the warning i spoke about robertc96@hotmail.com 2004-09-01 11:39:45 0000 sorry I misunderstood/misread what you said. spock@gentoo.org 2004-09-01 14:22:02 0000 Does changing "TryExec" to "Exec" in the desktop file work for you (even though it's in /usr/share/gnome/apps and not in /usr/share/applications)? leroutier@gmail.com 2004-09-01 14:53:23 0000 having both Exec & TryExec lines works, having Exec alone works, having only TryExec line fails as a side note, i just saw that nmapfe was present in 2 areas of the menu : network system tools because it interprets this line : Categories=Application;Network;System;Security;GTK was it done on purpose ? i did not have a look at .desktop files spec for a while, so i don't know if this Categories line is really correct. but that's a different issue the actual location of the file (/usr/share/gnome/apps) is not a problem. gnome 2.6 looks at both /usr/share/gnome/apps (old gnome 1 times) and in /usr/share/applications/ (i don't know if never gnome would do it that way) for compatibility, as it is a gtk 1 app, it could be good to let it where it is. (for people that still run gnome 1 if they exist). for the future, moving it to the good location should be better (as well as someone porting this app to gtk 2.x) other apps i have installed that put their desktop file in the old dir are : /usr/share/gnome/apps/Utilities/nmapfe.desktop /usr/share/gnome/apps/Applications/gnotime.desktop /usr/share/gnome/apps/Multimedia/mplayer.desktop /usr/share/gnome/apps/Internet/pan.desktop /usr/share/gnome/apps/Internet/gftp.desktop pan, gftp & gnotime are gtk 2 nmapfe & mplayer still use gtk 1 leroutier@gmail.com 2004-09-02 05:03:14 0000 from the latest .desktop file specification : http://freedesktop.org/Standards/desktop-entry-spec/0.9.4/ar01s04.html TryExec Filename of a binary on disk used to determine if the program is actually installed. If not, entry may not show in menus, etc. string NO NO 1 Exec Program to execute, possibly with arguments. string NO YES 1 so, Exec is mandatory, TryExec is not. they don't have the same purpose at all =========== for the Categories value, we shoud look at the latest menu spec : http://www.freedesktop.org/standards/menu-spec/0.8/ registered categories are there : http://www.freedesktop.org/standards/menu-spec/0.8/apa.html actual value is : Categories=Application;Network;System;Security;GTK it should be : Categories=GTK;Application;Network or Categories=GTK;Application;System;Security or Categories=GTK;Application;System;Monitor ========= for the location of the .desktop file itself, the menu spec only talks about /usr/share/applications : http://freedesktop.org/Standards/menu-spec/0.8/ar01s02.html and does not speak about legacy old directory structure. (where it is actually) leroutier@gmail.com 2004-09-02 08:36:35 0000 as a side note, to be compliant, the Categories line *MUST* end with a ';' or desktop-file-validate (from desktop-file-utils) would complain : /usr/bin/desktop-file-validate /usr/share/gnome/apps/Utilities/nmapfe.desktop /usr/share/gnome/apps/Utilities/nmapfe.desktop: error: value of key "Categories" is a list of strings and must end with a semicolon spock@gentoo.org 2004-09-03 06:34:11 0000 I've left the file where it is (it should be up to the upstream maintainers to move it to /usr/share/applications/) and I've added fixes for the bugs in the .desktop. Thanks for all the hints :)
