This document is ment as a simple howto for installing ESO SkyCat Tool on Debian and Ubuntu systems. It surely is not comprehensive nor authoritative, it's rather the simple description of “how we did it”. But it still may come in handy .

The original version from Petr Kubanek was only for Ubuntu 08.10, now it's extended to Debian 4.0 Etch and Ubuntu 09.04.

From Skycat download get skycat sources. As TclTk sources are included in Debian, you don't need them!

Then install required libraries:

• Ubuntu ⇐ 08.10:

user@host:~$ wget http://archive.eso.org/cms/tools-documentation/skycat-download/skycat-3.0.2.src.tar.gz
user@host:~$ sudo apt-get install tcl8.4-dev tk8.4-dev blt-dev itcl3.1-dev itk3.1-dev tclx8.4

• Ubuntu 09.04:

user@host:~$ wget http://archive.eso.org/cms/tools-documentation/skycat-download/skycat-3.0.2.src.tar.gz
user@host:~$ sudo apt-get install tcl8.5-dev tk8.5-dev blt-dev itcl3-dev itk3-dev

• Debian:

user@host:~$ wget http://archive.eso.org/cms/tools-documentation/skycat-download/skycat-3.0.2.src.tar.gz
user@host:~$ sudo apt-get install tcl8.4-dev tk8.4-dev blt-dev itcl3-dev itk3-dev tclx8.4 iwidgets4

• Ubuntu & Debian:

user@host:~$ tar -xzf skycat-3.0.2.src.tar.gz
user@host:~$ cd skycat-3.0.2/
user@host:~$ ./configure --with-tcl=/usr/lib/tcl8.4/ --with-tk=/usr/lib/tk8.4/ --with-tkinclude=/usr/include/tcl8.4/  --with-blt=/usr/lib

You will get error (libBLT24), which is expected. Now edit tclutil/configure, find libBLT24 and replace this line:

    BLT_LIBNAME=libBLT24${SHLIB_SUFFIX}
    BLT_LIBFLAG=-lBLT24

with

    BLT_LIBNAME=libBLT${SHLIB_SUFFIX}
    BLT_LIBFLAG=-lBLT

in case you have /usr/lib/libBLT.2.4.so.8.4. If you have some different version, please use it.

• Seems as case only for Ubuntu

You need to edit cat/generic/AstroQuery.h and put #include <string.h> to it, right after #include <cstdio>

#include <cstdio>
#include <string.h>
#include "WorldOrImageCoords.h"

Also edit astrotcl/generic/ImageIO.h, around line 307 should abs((float)bitpix_).. instead of abs( bitpix_):

    // reverse the effect of bzero and bscale
    double unScaleValue(double d) const {return (d-bzero_)/bscale_;}
 
    // return the size in bytes of a raw image pixel 
    int pixelSize() const {return abs((float) bitpix_)/8;}
 
    // member access

• Debian (seems to be not a problem in ubuntu?):

There is one more problem, you have to edit these files:

./cat/configure
./rtd/configure
./tclutil/configure
./skycat/configure
./astrotcl/configure

There is an error in those files, you have to change the line

system=MP-RAS-`awk '{print }' /etc/.relid'`

to

system=MP-RAS-`awk '{print }' /etc/.relid`

(redundant single quote mark).

• Debian, Ubuntu ⇐ 08.10:

user@host:~$ ./configure --with-tcl=/usr/lib/tcl8.4/ --with-tk=/usr/lib/tk8.4/ --with-tkinclude=/usr/include/tcl8.4/  --with-blt=/usr/lib
user@host:~$ make all
user@host:~$ sudo make install

• Ubuntu 09.04:

user@host:~$ ./configure --with-tcl=/usr/lib/tcl8.5/ --with-tk=/usr/lib/tk8.5 --with-tkinclude=/usr/include/tcl8.5 --with-blt=/usr/lib
user@host:~$ make all
user@host:~$ sudo make install

Please write to petr@iaa.es, and attach error description.
