Hi all, I’m new to Ruby, and I am trying to install Ruby-1.8.5 in my linux box. However upon configuring it, I encounter the following problem: Checking build system type… i686-pc-linux-gnu checking host system type… i686-pc-linux-gnu checking target system type… i686-pc-linux-gnu checking for gcc… gcc checking for C compiler default output file name… configure: error: C compiler cannot create executables See `config.log’ for more details. And GCC versin is: gcc version 3.4.6 20060404 (Red Hat 3.4.6-3) Can anybody suggest the right Ruby version I can install in my Linux? (I’ve also attached the config.log file). I’m planning to use Ruby On Rail with Ruby. Hope to hear from you again. – Edward ------------ Institute For Infocomm Research - Disclaimer ------------- This email is confidential and may be privileged.

It looks like you meant to set CFLAGS="-I/home/ewijaya/.ocaml/include …" but you actually have set is CFLAGS=“I/home/ewijaya/.ocaml/include …” The safest thing is to get rid of any environment variables like this which could affect compilation (CFLAGS, LDFLAGS, LD\_RUN\_PATH etc). Remove them from .profile or .bash\_profile or wherever else it is that you set them, then logout and login again. Or, being a bit more drastic, try: env -i ./configure … > And GCC versin is: gcc version 3.4.6 20060404 (Red Hat 3.4.6-3) > > Can anybody suggest the right Ruby version > I can install in my Linux? Well you didn’t say what Linux distribution you have, nor what version, but I expect ruby-1.8.5 will be fine. Of course, if you’re not comfortable compiling from source, then maybe you would be better off getting a pre-packaged ruby binary for whatever Linux distribution you have. Brian. ---

It’s been a while since I’ve been in Fedora/RH, but can you install it via yum? ie. # yum install ruby I am pretty sure I did that when I was trying to learn python a few years ago… – Samantha [http://www.babygeek.org/](http://www.babygeek.org/) “Beware when the great God lets loose a thinker on this planet.
