I think it shouldn't. Libtool is acting as it states and putting the dependency in $dependency_libs in the .la file. If we allow installing PIC archives (== installing convenience archives) then we can just wait for the day that someone comes and complains that this broke their program because he used a symbol from some completely unrelated library. (Imagine third-party shared libfoo containing code from your libmysqlclient that's both three years old, outdated, security bug ridden, and noone notices, but fourth-party program bar happened to link against that one before linking against a shared libmysqlclient.) > > Looking inside the "libtool" command and Googling a bit more, I found > > an ugly way around this.

Maybe this is a plan to kill pass_all on some more systems: allow a link flag that enables lt_cv_deplibs_check_method=test_compile, after spitting out some long warning. Then at least we can be a little more sure that we don't create fully broken libraries; and Kent's case would work (as its archive contains PIC code). Not sure though.
