Installing GTK+

CSWB requires GTK+ in order to compile.
GTK requires a C compiler, OpenVMS Porting Library, PERL, and AWK to compile.  With some editing it can compile without PERL and AWK.

The latest version of GTK+ provide by HP for OpenVMS is 1.2.10-A1.  It is available both as an installable PCSI included with the CSWB download, and as compilable source code.

The file GTK1210-OPENVMS-A1.SFX_AXPEXE was downloaded and ran to unpack the contents into the directory in which it is in (for this reason I ran it in the folder DKA0:[GTK.v1_2_10].

The file vms_build_setup.com needs editing to define the location of the GTK source tree, and the OPL.  For me it looked like this:

define /nolog groot /trans=conc dka0:[gtk.v1_2_10.]
define /nolog grootu "/dka0/gtk/v1_2_10"

define /noloj vjid dka0:[porting.dist.include]
define /nolog vjidu "/dka0/porting/dist/include"

define /nolog vms_jackets dka0:[porting.dist.lib]vms_jackets

Then the GTK+ compilation can be started by running vms_build.com

As is often the case, the default GTK+ source doesn't enable optimizations, but it's easy to edit the source, before compiling, to enable optimized code to be produced:

edit vms_cc.com
and change line:
  cc_debug =""
to:
  cc_debug = "/opt=(tune=host,inline=speed)"
