Re: Linking Problem with Solaris ld

[Bob Friesenhahn]

I believe that this problem is due to a missing LDADD in the libgcrypt 
Automake makefiles and I formally reported this as a bug to the 
libgcrypt developers some six or eight months ago.  I think I even 
supplied a patch.

The libgcrypt project is relying on implicit shared library 
dependencies as supported by Linux rather than the explicit 
dependencies which are necessary for portable libtool-based software. 
This is a common problem for projects which have only been tested 
under Linux.

I suggest that you report this as a bug to the libgcrypt developers.
