Subject: Re: [libpqxx-general] pqxx-config script ideas

However i found the pqxx-config doesn't do what most packages do and
instead actually gives the linker lines like:
pqxx-config --libs

This script was contributed by Arjen Baart. Frankly I have no idea what
similar scripts do in other packages, and don't want to mess with
something that may break compatibility... Could you help me out with a
reference or standard somewhere?
I'll agree it's not very pretty to have the option names in there, but
OTOH it could save a lot of trouble when using multiple libraries--and I
think "-L" is just about universally accepted. Removing it would
certainly break compatibility with existing Makefiles.
Mine included, if that matters at all :)
Possible solution: Another option which JUST prints the options, instead
of printing everything? For instance,
pqxx-config --libs --noflags
output: /usr/local/lib pqxx /usr/local/lib/libpq pq
Well, i certainly didn't mean remove --libs and --cflags.
I believe what gets me is that libpqxx depends on libpq, and libpq
doesn't include the flags in it's pg_config. Also, I know that libpqxx
depends on libpq, but for pqxx-config to automatically assume i want
libpg linked is correct, but what if I just wanted to know pqxx's
include and lib dir for use not only in compiling but other things such
as install scripts and such.
What i prepose is maybe:
pqxx-config --cflags - stays the same
pqxx-config --libs - stays the same
and adding
pqxx-config --includedir to output dir of the headers
"/usr/lib/pqxx" on my system
pqxx-config --libdir to output dir of the headers
"/opt/local/pgsql8/pqxx" on my system
as far as examples of behavior, i know of no standards. I've never
looked for a standard. However, that being said there are packages that
use both ways.
sdl-config is the same as current pqxx
pg_config however doesn't include flags.
pdflib-config uses both --libs with flags and --libdir without flags etc.
prce-config uses just flags
This was just something I noticed while hand writing Makefiles...
