trying to install postgres gem on fedora 12 ..

I get these errors :

gem install pg -- --with-pgsql-include-dir='/usr/include/pgsql' -- with-pgsql-lib-dir='/usr/lib/pgsql' Building native extensions. This could take a while... ERROR: Error installing pg:   ERROR: Failed to build gem native extension.

/usr/bin/ruby extconf.rb --with-pgsql-include-dir=/usr/include/pgsql -- with-pgsql-lib-dir=/usr/lib/pgsql can't find header files for ruby.

from yum list postgres*, the relevant stuff I have installed is:

Installed Packages postgresql.i686 8.4.2-1.fc12 @updates postgresql-devel.i686 8.4.2-1.fc12 @updates postgresql-libs.i686 8.4.2-1.fc12 @updates postgresql-server.i686 8.4.2-1.fc12 @updates

I tried to run this with the debuger: ruby -r debug extconf.rb --with-pgsql-include-dir=/usr/include/pgsql -- with-pgsql-lib-dir=/usr/lib/pgsql

this block of code in /usr/lib/ruby/1.8/mkmf.rb is where the error happens

topdir = File.dirname(libdir = File.dirname(__FILE__)) extdir = File.expand_path("ext", topdir) $extmk = File.expand_path($0)[0, extdir.size+1] == extdir+"/" if not $extmk and File.exist?(Config::CONFIG["archdir"] + "/ruby.h")   $hdrdir = $topdir = Config::CONFIG["archdir"] elsif File.exist?(($top_srcdir ||= topdir) + "/ruby.h") and     File.exist?(($topdir ||= Config::CONFIG["topdir"]) + "/config.h")   $hdrdir = $top_srcdir else   abort "can't find header files for ruby." end

it's looking for ruby.h in either: /usr/lib/ruby/1.8/i386-linux /usr/lib/ruby/

and config.h in /usr/lib/ruby/1.8/i386-linux

but those files are not there ..

so I did:

yum install ruby-devel.i686

now I get: can't find libpq-fe.h.

gem install pg -- --with-pgsql-include-dir=/usr/include/pgsql --with- pgsql-lib-dir=/usr/lib/pgsql Building native extensions. This could take a while... ERROR: Error installing pg:   ERROR: Failed to build gem native extension.

so I did:

yum install ruby-devel.i686

now I get: can't find libpq-fe.h.

try

yum install postgresql-devel

I allready have that:

The file is here: /usr/include/libpq-fe.h

but this doesn't work:

so I have these files in one place:

and then I have this file here: /usr/include/libpq-fe.h

I don't know if that means I have something wrong or incompatible on my system or if I should just try copying the file into the directory with the other ones

Try removing and re-installing the postgresql-devel package

yum remove postgresql-devel yum install postgresql-devel

Ok, I just did that, but I am having a problem that my gem command is not working all of a sudden. I had also tried to debug the extconf.rb, I had stepped inside a function that appeared to hang so I killed the process.

---- getcwd failure seems to indicate that your current path is a directory that no longer exists (like it was deleted)

cd /

then try again

That was strange as 'ls' showed I was in a directory, but that fixed that problem, but after the reinstall I still have the same problem:

also, the extra args don't allways seemed to matter as I get the same error for just "gem install pg" without the other args

My code is dying someplace in a log file operation in mkmf.rb while trying to find and process the header file:

I had put debug prints in the code and the reopen of stdout messed that up. In reality it tries the gcc command below. I did not have gcc installed, I then installed that. When I try the gcc command line from the log I get the error below, except I don't know what directory ruby issues that from:

gcc -E -I. -I/usr/lib/ruby/1.8/i386-linux -I. -D_FILE_OFFSET_BITS=64 - I/usr/include -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions - fstack-protector --param=ssp-buffer-size=4 -m32 -march=i686 - mtune=atom -fasynchronous-unwind-tables -fno-strict-aliasing -fPIC conftest.c -o conftest.i gcc: conftest.c: No such file or directory

I deleted the directory as you mentioned and reran it. I have some of my debug print code in the make file utility here in that log file as well:

so I just did: yum install gcc-c++ autoconf make

and deleted the ext directory and tried 'gem install pg' and go the same error.

in the mkmf.log I saw this:

18

ok, it seems to have worked. Thanks alot for your help ..

I tried to be carefull, but I realize that the way ruby functions return default values that debug code in the wrong place can mess up the return result. I often write code to return an explicit result. After not making any sense of why it was erroring our, I restored the non debug version of the mkmf.rb

I had same problem. But It's solved after run

yum install ruby-devel

Thanks.

just in case forks are still struggling with this(at least I was this morning on fedora core 14 beta). I solved the same problem by installing required development tools as:

sudo yum groupinstall 'development tools'

Cheers!
