Solaris 10, eggdrop 1.6.17, tcl 8.4.12 - undefined symbol

Post by jlewing »

A mysterious has popped up that I cannot seem to get rid of. This is eggdrop 1.6.17 being compiled on Solaris 10 using Sun Studio 11. I've submitted the output from compiling but the focus is only on these few lines:

...when compiling...
"./main.c", line 1104: warning: static function called but not defined: garbage_collect_tclhash()
"modules.c", line 1155: warning: static function called but not defined: open_listen()
"tcldcc.c", line 1161: warning: static function called but not defined: open_listen()

...and when linking, of course...

Undefined first referenced
symbol in file
open_listen modules.o
garbage_collect_tclhash main.o
ld: fatal: Symbol referencing errors. No output written to ../eggdrop
*** Error code 1

Any ideas?

The complete output

I used our default profile, which is setup for applications that take can use the higher optimization. I meant to remove that.

So the flags set now are only -xtarget=ultra -xarch=v9 -Xa. The tcl library on this system is 64-bit so the xtarget and xarch have to stay. The Xa just forces the system to use it's default ANSI conformance (ask our head of programming because i don't understand that logic).

The only thing that's added to the Makefile is $(LDFLAGS) on the linking line which adds -xtarget=ultra -xarch=v9 -Xa so that it will link properly.

And the results:

You can now compile the bot, using "make".

This may take a while. Go get some runts.

I don't use Solaris but I'd guess that problem has something to do with inlining; the Sun C compiler might be somehow confused by that; try to remove all inline specifiers in eggdrop sources (or use gcc)

I might be wrong but still, give it a try

Well, I got the garbage error to go away... first was the removal of inlining from the tclhash.c and tclhash.h files, and second was to include tclhash.h in main.c

The second error is a little more complicated as there is no net.h file included with 1.6.17, so I can't easily reference net.h from modules.c

Does anyone have a net.h file for 1.6.17?

open_listen modules.o

open_listen is defined in net.c, but there is no net.h referenced by modules.c

did you remove the inline specifier of open_listen() in proto.h and net.c? if not, do so

and there is no net.h, I don't know where you got your eggdrop sources, but there is no net.h in standard distribution, and no references to it

The fact there is no net.h is the point I was trying to make. I apologize, I didn't see the open_listen in proto.h. I did remove the inline from net.c. I'll reference proto.h and see what happens...

and the results are...

with some minor Makefile edits to include $(LDFLAGS) in the mod/*/Makefile's, everything seems to have compiled fine. I had to add the libtcl path to LD_LIBRARY_PATH to get ldd on all the files to check out but I can deal with that in the startup/shutdown script to avoid making it permanent in the /etc files.

Onto testing...
