Oggetto: Re: [tcljava-user] Creating an Eclipse plug-in for TclBlend

Hi Mo,

Thanks for the reply. I need to use TclBlend because I have pre-existing =
Tcl
code that uses Itcl and some other Tcl packages. I'm also guessing that
TclBlend
would be faster since it uses JNI.

In order to run Eclipse the user needs to have JRE installed on their
system. Is this
enough information to get TclBlend to work? Currently, I'm able to set =
to
env variables

setenv TCL_LIBRARY /a/b/c/lib/tcl8.4   where: /a/b/c/lib contains
libtcl8.4.so
and
setenv LD_LIBRARY_PATH /a/b/c/lib   where: /a/b/c/lib contains
libtclblend.so

However, I'm not sure how to set these environment variables within an
Eclipse plug-in.

Greg

Hi,
=20
Does anyone know how I could create an Eclipse plug-in for TclBlend?
I would want this plug-in to contain any required native shared=20
libraries so that
I could send this plug-in to anyone and they could use it without having =

to build
and install Tcl on their system first.

Really hard to do. You could build Tcl and Tcl Blend and zip up the
install tree but the trouble is that Tcl Blend depends on runtime
env vars to find the JDK that it is linked to. At runtime, it needs to
find jvm.dll and that means the PATH has to be searched. If you
knew the JVM location or the PATH that jvm dlls were found on,
then you might be able to do it. The trick will be getting all the
env vars setup correctly when the JVM process starts. The process
under Unix is the same except that you set LD_LIBRARY_PATH instead
of PATH (for Win32).

You would have a much easier time setting up a Jacl plugin since
all that is needed is to add tcljava.jar and jacl.jar to the CLASSPATH.
