How to fix tcsh (was [Bioclusters] recompiling redhat source rpms from .spec)

[Joe Landman]

Folks:

  Ivo and Goran are correct about the tcsh shipped with RedHat.  I will
send a quick note to RedHat tomorrow with this suggestion.

  The "fix" to tcsh to handle large files works like this:

1) pull down tcsh tarball (6.11.0 is the latest, I grabbed it from
ftp://ftp.gw.com/pub/unix/tcsh/)

2) untar-gzip into a directory.

3) run ./configure (alter any options you want)

4) now edit the Makefile, and add the following to DFLAGS= line
(something like line 139 or so).

	 -D__USE_FILE_OFFSET64 -D__USE_LARGEFILE64

5) run make

6) sanity check.

    (original RedHat tcsh)

    cp: missing destination file
    Try `cp --help' for more information.

    12 >cat dbEST.fsa >> d
    Filesize limit exceeded (core dumped)
    
    (with the compiled tcsh)
    
    [landman@genome.dtw.macsch.com:/scratch/bio/biotest]

    -rw-rw-r--    1 landman  landman  8981944038 May  9 00:36 d
    
And it seems to work.
