Error when compiling code on andLinux

This code previously compiled on Cygwin, any idea why this is bleeding errors now?

make -s smaug

Are you using gcc or g++; and which version are you using?

I was using gcc, 4.1.3.

<<deleted post about my knuckleheadedness>>

g++ SEEMS to have worked, let me check it out...good call on that.

Nope, EXACT same problem as before (can't find function in symbol table). At this point, I honestly have NO idea what to do about this. I suppose I can zip up the entire src if anyone wants to take a look.

Depending on what mode it's being compiling with, C doesn't support having different prototypes for the same function name. That is why you were getting errors for functions redeclarations one line after the first declaration; that's how I guessed that you were using gcc instead of g++.

Normally you just have -ldl as a linker flag; doesn't that make those go away?

Looks like this is a crossposted question of:
http://www.smaugmuds.org/index.php?a=topic&t=3772

-ldl makes it go away, but then it can't find the function in the symbol table which I was under the impression was a linking issue.

Correction to my above post.

It compiles fine with the -ldl flag, but the symbol still isn't found.

Okay, problem solved.

I stripped out the snippet, and reinstalled it clean. When I did the cedit, I did

cedit sayto create
cedit sayto code do_sayto

For some reason, that worked. I'm not sure if I fubar'd something in the naming of the functions or what, but it works.

Thanks again everyone for all your continued help.
