Hi,

I am trying to install the libneural library onto my Linux desktop
(Mandrake 9.1). I get the error “can’t find header files for ruby”

[ot@localhost ruby-libneural]$ ruby install.rb config
install.rb: entering config phase…
—> lib
<— lib
—> ext
—> ext/LibNeural
/usr/bin/ruby /home/ot/ruby-libneural/ext/LibNeural/extconf.rb
can’t find header files for ruby.
config failed
’system /usr/bin/ruby /home/ot/ruby-libneural/ext/LibNeural/extconf.rb '

try ‘ruby install.rb --help’ for usage

I am trying to install the libneural library onto my Linux desktop
(Mandrake 9.1). I get the error "can't find header files for ruby"

If it's a package from Mandrake, look if you have a package ruby-devel and
if it's installed

Many Redhat packages are split into ‘foo’ and ‘foo-devel’, where ‘foo-devel’
has the header files. Is there a ‘ruby-devel’ package you can install?

Regards,

Brian.

Guy, Thanks for the hint. Installed ruby-devel and it now works. You
have saved me a lot of head bashing.

Brian, thanks for replying. One of the things I like about Ruby is the
helpful community. :slight_smile:
