Shared host (Dreamhost)

Ruby Apps Ferret
1

I am unable to install gems on my dreamhost server since it’s just
shared hosting. I tried unpacking the ferret gem into vendor/ferret, but
to no avail.

Also how would I recompile the C extensions for the new platform?

Any ideas would be greatly appreciated.

Cheers, Simon

Not true. I use dreamhost and I’m able to completely compile my own
setup. Here’s how I do it. The following bash script creates your
own custom ruby environment, in which you can install whatever addons
and gems you want. Then just make sure you have

export PATH=“$HOME/extra/bin:$PATH”

in your .bash_profile script and also make sure your ruby scripts
point to $HOME/extra/bin/ruby.

#!/bin/sh

remove old stuff

rm -rf $HOME/extra/bin
rm -rf $HOME/extra/include
rm -rf $HOME/extra/info
rm -rf $HOME/extra/lib
rm -rf $HOME/extra/man
rm -rf $HOME/extra/src
rm -rf $HOME/extra/ssl
mkdir -p $HOME/extra/bin
cp $HOME/extra/binbak/* $HOME/extra/bin

create directory for compiling source code

mkdir -p $HOME/extra/src
cd $HOME/extra/src

download and compile source tarballs

Lots of good stuff.

Nicely done. I’ll try that out when I get home.

Thanks bud.

I think I figured out the issue. My script was being killed for some
reason when I ran it interactively and the ./config didn’t finish
correctly. I pipped the output to a file and ran the script in the
background with &

I’m not sure why this fixed it, but it seems to have so far.

I noticed that Dreamhost actually shut down my script occasionally
while I was running it, probably because it ties up the CPU for
extensive periods of time. I had to keep trying until it completed
successfully. I’m sure this annoys them somewhat, but I don’t have to
set up my environment from scratch very often.

And what about RoR applications - FCGIs

I have changed shebang location (#!) to my bin/ruby and application
didn’t run at all - webrick starts and runs correctlly, but
dispatch.fcgi - not

Does anybody fixed that case.

Carl,

When I run make for openssl I get the following errors, any ideas?

Cheers, Simon.
