[tcljava-user] compiling tclBlend

[yahalome <yah...@xo...>]

I try to compile tclBlend but failed. This is the error I get:

Is this a bug?

Humm, this seems to come from:

    jchar *buf;
    Tcl_UniChar *w;

(447)	w = buf;

(501)	length = (w - buf);

My guess here is that something about the declaration of the jchar type has
changed in the JDK headers you have on your system.

An old JDK install that I have on my linux box defines jchar like so:

typedef unsigned short  jchar;

So, there would be no problem with pointer arith in this case. How
is jchar defined in your j2sdk1.4.2_09 JDK on your linux box?
Take a peek at jni.h or related include file in the JDK to find out.

The Tcl Blend source may need to be updated to deal with this
issue. I have never seen it before so I am 99% sure that
it is an issue with the way JNI types are defined in this JDK release.

This remonds me of some old problems.  There was at least one Red Hat
release where Red Hat (*not* the Tcl maintainers) gratuitously decided
to change Tcl_UniChar to a 32-bit type.  The change was not well tested
(it made Tk leak memory like a sieve) and caused a good deal of grief
on the affected systems.  There still seem to be a fair number of them
out there.  The cure is either to rebuild Tcl/Tk from source or to 
install ActiveTcl and build against that - either of those approaches
won't have the misdefinition of Tcl_UniChar.

Well, I am not sure if that is the problem here but I did notice that the user
was building with Tcl 8.4.5. You really should upgrade to Tcl 8.4.11 since
that is the most recent version that Tcl Blend was tested with. If that does
not do the trick, then could you find out what type Tcl_UniChar is getting
set to so we can find out why the "w - buf" operator is failing to compile.
