busybox in embedded linux shows “applet not found”












5















I compiled busybox myself,and I put it in our embedded linux. But I have some questions.



Question 1:When I try to use some command such as gzip,it prints "gzip: applet not found".While I checked the menuconfig of busybox,I make sure that I've selected "gzip".



Question 2:I used to work with VIM,but busybox just provide VI.So I make a link VIM to VI,but when I typed vim and run it,it also show "vim: applet not found".



Anybody can help me with this problem that "applet not found"? Thank you very much.



PS:I'm confused with the "applet" of busybox,what it is? Like "applet" in java?

  • Looks like your shell is not finding busybox in its path. Google "busybox shell path" to find the remedy.

    First of all, try to execute gzip like "busybox gzip". If it works, then problem is in applet links (symbolic, hard or micro scripts). If not, then gzip applet is likely not compiled into busybox (although it seems that links point to busybox executable because you get "applet not found" message). Applets are commands/utilities supported by busybox.

    The way busybox work is it looks at it argv[0] parameter which is the name of the symlink; vim in your case. It then does a look-up and it has no applet named vim. You can make a script that does busybox vi and symlink that script to vim. The syntax busybox applet, is another way to select the program; but why not just type vi. An applet in busybox parlance is the emulated program. busybox has base infrastructure (command line parsing, etc) with a main driver file that is an applet emulating the normal program.

The answer to questions 1 and 2 is: you must set your PATH variable first or compile busybox with FEATURE_PREFER_APPLETS enabled. You can set the PATH variable with:



$ export PATH=/bin:/sbin:/usr/bin:/usr/sbin


A busybox applet is a small application that is usually found in the UNIX common utilities (defined in the POSIX standard). This applets are compiled into a single executable: busybox.
