Re: [Plplot-devel] Splitting off libpltcl and greatly simplifying library linking options

[Alan W. I. <ir...@be...>]

I don't have the problem here.

I am confused by your result since libplplot has no references (I believe,
although perhaps I am missing something here?) to libgd when dynamic drivers
are enabled.  Instead, the gd driver (which itself is linked to libgd et al)
is dlopened at run time.

Did you forget to configure --enable-dyndrivers?  The current CVS won't work
without it although I intend to address that issue once any problems with
the --enable-dyndrivers case are sorted out.
