tcltk && C program as shared library

[pinkipons]

Hi!
I'm installing a tcltk program that requires a C program as a shared library.

When I compile it with
gcc -shared -fPIC -o name.os name.o

I get the following:

ld: 0711-317 ERROR: Undefined symbol: .Tcl_CreateObjCommand
ld: 0711-317 ERROR: Undefined symbol: .Tcl_PkgProvide
ld: 0711-317 ERROR: Undefined symbol: .Tcl_SetResult

ld: 0711-317 ERROR: Undefined symbol: .sin
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
collect2: ld returned 8 exit status


What am I doing wrong?
Thanks for your help,

Looks as though you forgot to link with the Tcl libraries (or the Tcl stub libraries, if that's what the extension was built to use). Double check whatever compilation instructions you have for the library to see what all it needs to link with.

You might also want to check with the Tcl'ers Wiki (

http://wiki.tcl.tk)

for more information on compiling Tcl extensions. The page "How to write C-coded extensions for Tcl,"

http://mini.net/tcl/2334.html,

might be a good place to start, following whatever links there that you find most helpful. - Ken Jones, President
