I make no guarantee whatsoever that the same step will work for others but at least it should point you in the right direction. Also, I am a biologist by training so I only got pgaccess working by fudging (that is, trial and error) this means that some of the steps may be unnecessary (e.g. compiling $postgreSQL_source/src/interfaces/libpgtcl as both a shared and static library) and they certainly haven't been optimised (I know nothing about compiler switches etc.).</P> <P><B>1) Requirements:</B></P> <UL> <P>You will need:</P> <UL> <LI>postgreSQL source (http://www.postgresql.org)</LI> <LI>tcl8.0 source (http://www.tclconsortium.org/)</LI> <LI>tk8.0 source (http://www.tclconsortium.org/)</LI> <LI>pgaccess source (http://www.flex.ro/pgaccess)</LI> </UL> </UL> <P><B>2) Installation:</B></P> <P>a) tcl/tk:</P> <UL> <P>You must first install tcl and then tk (in that order). I just used ./configure, no switches and gmake. Their installation should be trouble free. Then you must move headers and libraries to the right places so:</P> <P>Header files: both tcl and tk have a header file (tcl.h and tk.h). The tcl.h file is in $tcl_source_dir/generic and the tk.h file is in $tk_source_dir/generic; both should be copied to /usr/local/include.</P> <P>Libraries: compilation (with cc) of tcl and tk yield libraries libtcl8.0.a and libtk8.0.a in $source_dir/unix. Both should be copied to /usr/local/lib.</P> </UL> <P>b) postgreSQL:</P> <UL> <P>Make sure you have a fully patched postgreSQL source. If your ./configure says it can't load 'IRIX' settings then you most probably will need to patch ./configure.</P> <P>Configure using ./configure with the following switches: ./configure --with-includes=/usr/local/include</P> <P>--with-libraries=/usr/local/lib --with-tcl [this and previous line as one]</P> <P>Then make, make install as usual</P> </UL> <P>c) Compiling libpgtcl:</P> <UL> <P>The source for libpgtcl is in $postgreSQL_directory/src/interfaces/libpgsql.</P> <P>I do this twice. Once with just gmake. This produces a static library libpgtcl.a which I leave where it is (I don't know what to do with it but it may just come in handy). The I modify Makefile manually with a text editor. Essentially I modify two line:</P> <P>before:</P> <P># Shared library stuff</P> <P>install-shlib-dep := shlib :=</P> <P>after:</P> <P># Shared library stuff</P> <P>install-shlib-dep := install-shlib shlib := libpgtcl.so.1</P> <P>Then gmake -f Makefile_modified. This creates two shared (.so) libraries: libpgtcl.so and libpgtcl.so.1. I can't tell the difference between them so I copied them both to /usr/lib/.</P> </UL> <P>d) running pgaccess:</P> <UL> <P>Uncompress pgaccess (usually with gunzip and tar). So long as 'wish' (a binary produced when compiling tk8.0) is somewhere in your path, you should be able to run pgaccess with:</P> <P>wish -f $pgaccess_dir/pgaccess.tcl [postgreSQL_database_name]</P> </UL> <P>e) et voila!</P> <P><B>3) Concluding remarks:</B></P> <UL> <P>As I stated at the start of this document, following the procedure indicated above worked for me. I am sure, however, that a few of the steps are unnecessary/non-optimised/stupid etc. If any Unix (IRIX) boffin is reading this and you spot anything you would like to comment/correct etc. please e-mail me (stuart@ludwig.ucl.ac.uk). Also, if you just have questions and think I might help, please contact me at the same e-mail.</P> <P>Finally, I can accept no responsibility if these steps don't work for you or if it all goes horribly wrong and you 'damage' your computer trying them. Let common sense prevail!</P> </UL> <P>Good luck</P> <P>Stuart Rison LICR University College London London W1P 8BT<BR> <A HREF="mailto:stuart@ludwig.ucl.ac.uk">stuart@ludwig.ucl.ac.uk</A></P> <a href="index.html#start">Back to index</a> </BODY> </HTML>
