Hi,
I’m trtying to install postgress v0.7.9.2008.01.28 gems:
C:>gem install -v=0.7.9.2008.01.28 postgres
Building native extensions. This could take a while…
ERROR: While executing gem … (Gem::Installer::ExtensionBuildError)
ERROR: Failed to build gem native extension.
ruby extconf.rb install -v=0.7.9.2008.01.28 postgres
checking for main() in /ms/libpq.lib… no
Could not find PostgreSQL build environment (libraries & headers):
Makefile
not
created
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
Provided configuration options:
–with-opt-dir
–without-opt-dir
–with-opt-include
–without-opt-include=${opt-dir}/include
–with-opt-lib
–without-opt-lib=${opt-dir}/lib
–with-make-prog
–srcdir=.
–curdir
–ruby=c:/ruby/bin/ruby
–with-pgsql-dir
–without-pgsql-dir
–with-pgsql-include
–without-pgsql-include=${pgsql-dir}/include
–with-pgsql-lib
–without-pgsql-lib=${pgsql-dir}/lib
–with-/ms/libpqlib
–without-/ms/libpqlib
Gem files will remain installed in
c:/ruby/lib/ruby/gems/1.8/gems/postgres-0.7.9
.2008.01.28 for inspection.
