Обсуждение: getaddrinfo.c error
Hi,guys.I am a student who want to study PostgreSQL.I encountered the following errors which I don't know how to fix while I using eclipse to built pgsql:
" ../src/port/getaddrinfo.c:360: error: conflicting types for 'getnameinfo' /usr/inlclude/netdb.h:653: note: previous declaration of 'getnameinfo' was here"
but other similar functions such as getaddrinfo(...) declared in getaddrinfo.h work right.so why getnameinfo(...) produce the errors.can someone give me a tip to fix the problem,that's would be very helpful to me.Thanks very much

It's an integrated development environment. I assume you're using GCC as your compiler, since that's what Eclipse's C development tools want to use, but how did you set the project up? Are you using PostgreSQL's original `configure' script? Or did you just import the sources into Eclipse and let it create a new build script? You should really just stick to using PostgreSQL's existing, tested build tools and a well tested and supported compiler. You can still use something like Eclipse if you want to use an IDE to edit the sources - you just need to set the project up to use the existing postgresql configure script etc when building. If you do not think that your use of Eclipse is the problem, then please try running "./configure" then "make" on a fresh copy of the PostgreSQL sources to demonstrate that the problem happens even without Eclipse's involvement. -- Craig Ringer

I would suggest manually running ./configure with whatever options are appropriate initially to create the Makefile, then just have Eclipse use this Makefile to rebuild the project after you edit code.

Relying on manual invocation of configure is a sure recipe for hitting weird breakage anytime somebody changes the configure input files ... Surely there's a way to teach Eclipse to do that when needed? regards, tom lane

I think our makefiles are set up such that they will re-run configure in some of its input files have changed. I know they do for me when I cvs-update and configure itself has changed. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc.

I believe they will re-run config.status to regenerate the output
files. This is not the same thing as re-running the configure script.

This is not the same thing as re-running the configure script. It runs config.status --recheck and then config.status for the output files, which is ultimately pretty much the same as rerunning configure.
