Hi there,
*1. THE SITUATION*
I try to create my first Sinatra (Ruby) app. Therefore I want to use the
"dm-sqlite-adapter" gem,
which shall now be installed after "data_mapper" was installed before.
*2. THE PROBLEM*
So I did run:
sudo gem install dm-sqlite-adapter
>
in the terminal and got the following output:
Building native extensions. This could take a while...
ERROR: Error installing dm-sqlite-adapter:
ERROR: Failed to build gem native extension.
> /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
> extconf.rb
checking for sqlite3.h... no
*** 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.

In addition, in the mkmf.log it's written:

*3. A SOLUTION, not yet.*
Does anybody know how to tackle this issue?
I did already look on several websites (including a question at
Stackoverflow<http://stackoverflow.com/questions/12451964/gem-install-sqlite3-gives-error-sqlite3-h-is-missing>,
or
this<http://stackoverflow.com/questions/1143776/install-sqlite3-on-mac-osx>one)
where they recommend to use "sudo
apt-get install libsqlite3-dev" which is only valid for Ubuntu or similar
Linux operating systems. I can't seem to find the right way to make the
sqlite3.h (Header file) detectable.
But I did install sqlite3 using MacPorts with:
sudo port install sqlite3
>
> and asking the terminal with "which sqlite3" results in:
/opt/local/bin/sqlite3
So, sqlite3 seems to be installed properly.
*4. ASK FOR HELP*
Any tip or link is very much appreciated!
Thanks in advance,
- Alex
