[GRASS-user] Delete layer from vector

GRASS GRASS user

Hi

I have imported a vector from a shape file and it has now three layers (layer numbers). I am only interested in layer number three and would delete the other two as they semm to be artefacts from the onversion. Is this possible?

Thanks,

Rainer

Dear All,

The old problem of the configure script not being able
to find the readline library seems to continue in the
new version og GRASS 6.2.2 and 6.3.

I am using Mandriva 2007. Is there a workaround for
compiling with readline or the only choice I have is
to not use the --with-readline option.

Regards

Venka

First, note that the only place where readline is used is when
r.mapcalc (or r3.mapcalc) read expressions from the terminal.

If you're entering simple expressions, you can just pass them as a
command-line argument. For complex expressions, it's probably better
to enter them into a file with a text editor, then use r.mapcalc on
the file.

If you decide that you need this functionality, you can omit the
--with-readline switch then hack the configuration files manually once
configure has completed.

Specifically, you need to:

1. Define the following variables in include/Make/Platform.make:

  READLINEINCPATH =
  READLINELIBPATH =
  READLINELIB = -lreadline -lncurses
  HISTORYLIB = -lhistory

[Note that -lncurses could be replaced with -lcurses, -ltermcap or
-ltinfo if you have those libraries rather than libncurses.]

2. Define the following macro in include/config.h:

  /* define if readline exists */
  #define HAVE_READLINE_READLINE_H 1
