From: Blake Miller Date: 2007-04-07T02:37:40+09:00 Subject: mkmf have_header function on Windows XP I'm trying to get an extension built on WinXP. It's the PL/Ruby library for writing stored procedures for PostgreSQL. I'm posting this because it seems like a generic enough question. I've got Ruby 1.8.6. PostgreSQL 8.2 I'm running command: ruby extconf.rb --with-pgsql-dir="C:\PostgreSQL\8.2\" --with-pgsql-dir="C:\PostgreSQL\8.2\lib" --ruby="C:\ruby" And it's complaining that it can't find a header file that I know exists where it's looking. The error is: checking for C:\PostgreSQL\8.2\include\server/catalog/pg_proc.h... no I've tried all sorts of paths, and have begun digging into extconf.rb, but no matter what the path, the have_header() function always causes the above error. -- Posted via http://www.ruby-forum.com/.
