Thanks Chuck,

I want to link with dll but couldn't get it to work

I was able to compile and link with the static lib
# compile
gcc -o getdata.o -c getdata.c -DGDBM_STATIC
gcc -o utils.o   -c utils.c   -DGDBM_STATIC

#link
gcc -static -o /home/jeff/getdata.cgi getdata.o utils.o -lgdbm

but not with this long command
gcc -static -o /home/jeff/getdata.cgi getdata.c -lgdbm utils.c -DGDBM_STATIC

Okay, so it appears that you want to link statically and not use the
dll, right?  You can do this because the gdbm package provides *both* a
static lib *AND* a dll+import library.

If you want to link statically, then you need to add "-static" to your
link command.  Now, since you are going straight from .c files to an
executable all in one step, your compile command and your link command
are the same.  So, do this:

gcc -static -o /home/jeff/getdata.cgi getdata.c -lgdbm utils.c
-DGDBM_STATIC

You could also do this:

# compile
gcc -o getdata.o -c getdata.c -DGDBM_STATIC
gcc -o utils.o   -c utils.c   -DGDBM_STATIC

#link
gcc -static -o /home/jeff/getdata.cgi getdata.o utils.o -lgdbm

but not with this long command
gcc -static -o /home/jeff/getdata.cgi getdata.c -lgdbm utils.c -DGDBM_STATIC
