The files needed are listed in the man page for solaris's in.ftpd.
This includes character special files needed in ~ftp/dev. I
have done this and now have working anon ftp.

Aki Sasaki <Aki.Sasaki@barra.com> sent the proceedure, patch and
static-ls.c included at the end of this mail for building a static ls
on solaris based on the ls in gnu fileutils-3.16. I have just done
this and it works.
Thanks again

Hi!
I have made a small procedure for compiling ls static on Solaris. Tested on Solaris 2.5.1 with gcc and fileutils-3.16
Basically I adapted the current procedure to the new fileutils (old one was for fileutils-3.13) and use the same static-ls.c from Emil.
It might be good to put it online so I'm CC'ing this to Darci who maintains the HowTo for WuFtpd on Solaris

-------------- Ok, a small procedure to build a staitc ls.
1. get fileutils-3.16 from your favourite GNU mirror site. 2. Unpack 3. apply the patch (see below) 4. copy static-ls.c (see below) to the fileutils-3.16/src/ subdirectory. static-ls contains some the functions that Solaris does not provide statically. This file is the work of Emil Isberg <eig@mds.mdh.se> and Brett Porter <porter@carbon.chem.nyu.edu>. Great work! 5. cd into fileutils-3.16 6. run configure 7. make 8. cd into src 9. test with truss ./ls -la 2> err err should not contain any references to any libs... file ls should report somethink like ELF 32-bit MSB executable SPARC Version 1, statically linked, not stripped
10. (Optional) strip ls
You can now copy it into your bin directory.
Files needed.
