Wolfgang,
I could not get what you sent me to compile; however, I believe that I
have fixed the problem (or at least fond a work around).
In line 124 of common/Make.global_options, I changed
DEAL_II_ADD_SONAME = -Wl,-dylib_install_name -Wl,$(call
DEAL_II_SHLIB_NAME,$(1))
to
DEAL_II_ADD_SONAME = -Wl,-dynamic -Wl,-install_name -Wl,$(call
DEAL_II_SHLIB_NAME,$(1))
While searching for information about this problem, I saw that this
particular syntax was used somewhere else. All of the libraries are
now linking correctly, and the examples are running.
Additionally, I made this change on my 10.5 system, and it works as
well.
Finally, do you know of a good reference to read more about these
topics? I find myself devoting a significant amount of time to this,
and while I usually can get things working, I would like to have a
more complete knowledge of the subject.
Thanks again for your help,
Jon
