Installing the SNAP Toolkit for use with WarpVision

Building he snaptv and snapov plugins requires access to some SNAP SDK headers and to n_ga.lib.

You can follow the directions that come with the SNAP SDK and build the full toolkit. However, since only one library is required the following guide will get you there faster.

Unzip the contents of

• snap_sdk_3.1-r23-os2.zip
• snap_sdk_3.1-r23-src.zip
• snap_sdk_3.1-r23-util.zip

to a working directory preserving the paths.

Edit start-sdk.cmd

Add definitions for SCITECH and SCITECH_LIB. Mine are

SET SCITECH=J:\sla_dev2\SDKs\snap
SET SCITECH_LIB=J:\sla_dev2\SDKs\snap

Change the hardcoded references in

call C:\SCITECH\bin-os2\set-vars.cmd
set DEFPATH=%SCITECH%\redist\release;%DEFPATH%
call C:\SCITECH\bin-os2\wc11-o32.cmd

to read

call %SCITECH%\bin-os2\set-vars.cmd
set DEFPATH=%SCITECH%\redist\release;%DEFPATH%
call %SCITECH%\bin-os2\ow10-o32.cmd

This assumes you will be using OpenWatcom.

REM out the statement

cd %SCITECH%\EXAMPLES\SNAP\GRAPHICS

Edit bin-os2\set-vars.cmd

Change the hardcoded paths in the following statements

SET VA3_PATH=C:\C\IBMC30
SET WC10_PATH=C:\C\WC10
SET WC11_PATH=C:\C\WC11
SET OW10_PATH=C:\C\OW10
SET BC2_PATH=C:\C\BCOS2
SET EMX_PATH=C:\C\EMX
SET VA365_PATH=C:\ibmcxxo
SET OS2TK_PATH=C:\TOOLKIT

to point to your local paths. REM out or ignore unused items. Point the OW10_PATH variable to your OpenWatcom installation. Ow10-o32.cmd is sufficiently generic to be used with all the known OpenWatcom versions.

Build n_ga.lib

From the SNAP SDK root directory, run

start-sdk.cmd
cd src
dmake targets\snap
set CHECKED=1
start-sdk.cmd
dmake -u targets\snap

This should build the both release and debug versions of n_ga.lib. The -u option forces a full rebuild.
