You're breaking on those? I remember just seeing them as warnings. They are
symbol conflicts between the regular expression stuff in the Math library
(see regex(3)) and PCRE. Under normal circumstances, PCRE wins and we end up
actually using our own symbols. As long as there is no namespace protection
or two-level linking (which we shied away from earlier), we're stuck with
the existence of multiple symbols. From the man page of ld(1):
When creating a output file with the static link editor
that links against dynamic libraries, the references to
symbols in those libraries can be recorded at static link
time to bind to a specific library definition (two-level
namespace) or left to be bound at execution time to the
first library in the search order of the program (flat
namespace). A program, its dynamic libraries and its bun-
dles may each be either two-level or flat namespace
images. The dynamic linker will bind each image according
to how it was built.
As far as I have taken the time to figure this out (AFAIHTTTTFTO?), the PCRE
library is linked statically into httpd, so its symbols don't have to be
satisfied at runtime. Feel free to shoot me down on this though.
