[Linux] Problem installing gem in RubyStack 1.2-beta-0

Hi,

I encountered the following when trying to install sqlite3-ruby gem. Note stack installed as non-root user:

Hi rob99,

It seems that sqlite gem can not find the sqlite directory. Try this:

Hi beltran,

Thanks for your response. I tried your suggestion but got same result:

bash-3.00$ gem install sqlite3-ruby -- --with-sqlite3-dir=/export/myhome/rubystack-1.2-beta-0/sqlite/

Hi rob99,

It seems that the gem can not load the libraries. Please try this, I have installed sqlite3 gem successfully:

$ ./rubyconsole
bash$ . scripts/setenv.sh
bash$ gem install sqlite3-ruby -- --with-sqlite3-dir=/export/myhome/rubystack-1.2-beta-0/sqlite

beltran, thanks once again.

Unfortunately I got the same result as before.

Do you think there’s any merit to the link above, which says ruby need to be compiled with sqlite present?

Mmmm, I don’t think that this is the problem. I could install the gem in the Rubystack.

Do you have the build-essential packages? These packages are required to compile the sqlite3 gem.

I think so, though as I mentioned – I’m not root. Not sure if that has any implications….
