0004700: dlltkanim.so wrongly linked

I think you're supposed to load labltk.cma before tkanim.cma.

But even so, another problem appears:

Cannot load required shared library dlltkanim.
Reason: ./dlltkanim.so: ./dlltkanim.so: undefined symbol: Tk_ImageObjCmd.

There is an explanation in otherlibs/tabltk/tkanim/Makefile:

# tkAnimGIF.c used the function Tk_ImageObjCmd, which is not available
# in a plain Tk installation. Should we disable this subdirectory ?

Should we, indeed?

Let's remove the tkanim directory.
Since from tk8.4 (or somewhere), animated gifs can be loaded by pure tcl/tk.
labltk does not handle animated gifs unless it is extended somehow, but anyway, the current code does not work.

To xleroy: indeed. I've probably over-simplified my original bugreport to what I thought was the actual issue.

I was not expecting this error message for this buggy situation... When I usually get such a message, it is indeed a stublib that was linked with a missing -lfoo. But here, cltclinterp is defined in the C stubs of labltk.cma (dlllabltk.so), so I guess it's fine (even though some might argue that dlltkanim.so should be linked against dlllabltk.so...)

tkanim is removed from the source code in the trunk,
due to its old and unmaintained status.
If someone really wants to have animated gif in labltk, he/she should try
more pure tcl way, using image photo command.

Please close the issue.
