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 --Chuck -- Want to unsubscribe from this list?
