Hi all,

I can’t install some gems (nokogiri, hpricot, sqlite3-ruby…) on Slitaz  
Linux distro, it fails when it is builiding.

Slitaz is a minidistro with busybox, and I think I have installed all  
the development tools: gcc, g++, make, automake, libc, … and ruby-dev  
of course.

Maybe can it be a path problem?

I have reduced the problem to “try\_cpp”: gem calls extconf.rb, and it  
calls mkmf.rb that fails to compile a cpp.

# ruby -r mkmf -e ‘try\_cpp(“”)’ works on my main computer, but here no

☹

The outputs are here: [http://pastie.org/1104033](http://pastie.org/1104033)

I don’t know how to solve it, I’m new on Ruby, but I really would like  
to get it works, and also upstream the solution to the Slitaz package  
mantainers if needed.

Thanks!

For nokogiri you need all these (I _think_, I can’t confirm right  
now): libxml2 libxml2-dev libxslt libxslt-dev

Use your system’s package manager to install them and try ‘gem install  
nokogiri’ again.

Thanks Pablo,

I didn’t have installed libxml2 nor libxslt, and this has works for  
nokogiri but I had to solve the main problem first.

Solution:  
The needed packages for build gems are: gcc, glibc, binutils and  
linux-headers (plus dependencies of gems itself)

And I didn’t have linux-headers installed, now it’s works and I’m happy  
🙂
