Hello,

for my work I would have access to shared libraries.
unfortunately the source code of gforth is not trivial and
hence I have found and tryied so far:

s" db/script.so" open-lib constant so  \ load my small dynamic link lib
s" script" so lib-sym wcall \ call the function script

I set a breakpoint at script() but ..

Breakpoint 1, script (args=0x2aaaac0ff000 "") at script.c:10
10		printf("<h1>Hello From Script</h1>");
(gdb) bt
#0  script (args=0x2aaaac0ff000 "") at script.c:10
#1  0x0000000000408edc in gforth_engine (ip0=0x2aaaac0ff000, 
ip0@entry=0x2aaaab903620, sp0=0x2aaaac0feff8, rp0=0x408ebc,
    rp0@entry=0x2aaaac108c00, fp0=0x2aaaac104000, lp0=0x6c <Address 
0x6c out of bounds>, lp0@entry=0x2aaaac10da00 "") at prim:2480
#2  0x0000000000411a3b in gforth_go (image=image@entry=0x2aaaab8f9038, 
stack=<optimized out>, stack@entry=4,
    entries=entries@entry=0x7fffffffe4b0) at ./main.c:754
#3  0x0000000000404513 in main (argc=<optimized out>, argv=<optimized 
out>, env=<optimized out>) at ./main.c:2349

I only can guess what the meaning of the parameters ip0, ip0@entry ... are

I even haven't found anything in the documentation about open-lib, 
lib-sym and wcall
(there are more system related words to explore)

so, how is the interface for wcall defined ?

I would be grateful for any help

best wishes
Andreas Klimas
