Apps won't compile

[John Eikenberry [MSAI]]

Hello,

I finally found the time to upgrade to 1.0 but I can't seem to get any of 
the apps to compile. I keep getting the error:

gcc -g -L../../swarm/lib -L/usr/X11R6/lib -L/usr/local/lib -L/usr/lib  -o 
hello-world main.o Person.o Counter.o PplModelSwarm.o PplObserverSwarm.o  
-lanalysis -lsimtools -ltkobjc -lactivity -lrandom -lswarmobject 
-lcollections -ldefobj -ltclobjc -lBLT -ltk -ltcl -lXpm -lobjc -lX11 -lm
/usr/lib/libtcl.so: undefined reference to `dlerror'
/usr/lib/libtcl.so: undefined reference to `dlopen'
/usr/lib/libtcl.so: undefined reference to `dlsym'
make: *** [hello-world] Error 1                      

I get this for all the demos (plus my own hacks). So you have 
more of a context here is a rundown of what I did & have installed.

First I upgraded my tcl/tk libs to 7.5/4.1 (off the redhat 4.0 cd). I 
then set about compiling BLT2.1 and libtclobj-1.1b6. I had some trouble 
with these. BLT needed to have its Makefile altered to look at the right 
directory. For libtclobj I had to alter the configure file so that it 
didn't insist on libtcl.a/libtk.a and I could use libtcl.so/libtk.so 
instead. I then applied the patch so I could compile it with my gcc-2.7.2.1 
which has been patched with Scott Christley's patches (960906). This was 
Ted Belding's patch that he made against litclobjc-1.1b3. 1 hunk was 
rejected and I fixed it by hand (it was easy... the code had just moved
a few lines). Swarm compiled with no problem, but then none of the apps 
would compile (as I explained above).

I searched through the mail archives for these errors or a similar 
problem and had no luck. I have just started coding my own application 
and am nearing the point when I'll want to start trying to compile it... 
So any tips or help will be greatly appreciated.

Thanks,

John Eikenberry
