I am working here on Solaris and i have ruby-installation.
One installation is local, self-compiled and with that version
everything is working fine.
I also have a system-installation and with that ruby-version i cannot
find header files.
For example installing the gem sqlite3-ruby
gem install sqlite3-ruby --
(sqlite3.h is in home folder) and thats working.
Same command with the system ruby, i get that it cannot find the
According to the admin, the dev-files for ruby are installed (maybe
Did you check a mkmf.log file under the gem path?

By the looks of it, it seems to use a different compiler, how can i
May there is a ‘Makefile’ in the directory,
GEM_HOME/gems/sqlite3-ruby-x.x.x/ext/, so you can figure out that file
to set CC and CFLAGS for your environment.
It seems like ‘mkmf’ is using CC which used to compiling her base
ruby. I also got similar errors last one month, so I did edit Makefile
and make extension directly and then install gems via setup.rb
figure out Makefile
$ vi sqlite3-ruby-x.x.x/ext/sqlite3_api/Makefile
compile extension. go to sqlite3-ruby-x.x.x/ext/sqlite3_api. and
$ ruby extconf.rb (you can use --with-NAME-include or lib. this will
$ make install
go to root of sqlite3-ruby. install gem directly,
$ ruby setup.rb all --without-ext
but be careful. this gem will not controlled under gem system. you can
build gem also, not use setup.rb, if you want.
my english is very poor, but I think you can very well.
