1: Error Making JavaBlend
Posted by Chris Yeo on 04/08/01 02:59 PM
Anyone has any idea on how to solve this error during making of
JavaBlend

db.c: In function `DbGetHandle':
db.c:709: `TclData' undeclared (first use in this function)
db.c:709: (Each undeclared identifier is reported only once
db.c:709: for each function it appears in.)
db.c:709: `tdPtr' undeclared (first use in this function)
db.c:711: too few arguments to function `NsTclGetData'
make[1]: *** [db.o] Error 1
make[1]: Leaving directory `/home/nsadmin/nsjavablend-0.0.9/src'
make: *** [all] Error 1

Any help is appreciated. Thanks.

What version of Tcl does JavaBlend support, and which version are you compiling with?  I'm just guessing but this looks like it could be a Tcl7 vs Tcl8 kinda problem.

I'm having the same problem while installing nsjava-0.0.9, has anybody figured it out yet?

I need more information.  Could you run configure and post the output?  Also what version of aolserver are you using, and what jdk are you using?

I'm using AOLserver-3.4 and ibm-jdk-1.1.8.  The problem comes when I try to make after successfully running configure.  It reports that TclData is undeclared in the same error message as above.  I looked everywhere for it and ended up finding its struct declaration(on line 144) in the file tclinit.c inside the directory aolserver3.4/nsd.  The only problem is there does not exist a variable dbs inside TclData.  In the function DbGetHandle, nsjava tries to use TclData->dbs (on line 709), which does not exist even if it could find the definition for TclData in tclinit.c.  The output when I run make is included below if it helps.

Thanks for the help if you can offer some.  I really want to get this webmail thing working.

6: Response to Error Making JavaBlend (response to 1)
Posted by Dan Wickstrom on 08/03/01 01:19 AM
The problem appears to be with aolserver 3.4.  This is the first time I've tried building nsjava with aolserver 3.4, and it failed with the same error that you have.  I should be able to come up with a fix for it pretty soon, but in the meantime, you can try one of the earlier aolserver versions.  I'm currently using aolserver3_2+ad12, and nsjava builds fine with that.

I'll post here when I have a fix for the 3.4 problem.

I fixed this build error which occurs when building with aolserver version 3.4. The new version (nsjava-0.0.10) is available at http://nsjava.sourceforge.net.
