Does anyone know how to solve ‘No such file to load – RMagick’ on
‘Instant Rails’?

What do I need to do?

Install the headers for ImageMagick. If you’re using a distro with a
package manager, it will probably end in -dev.

Ok, I just looked in the Ubuntu 8.10 manager and you want something
along the lines of libgraphicsmagick1-dev

But that’s just a guess, I don’t know exactly. However, if you’re using
Ubuntu you can just use synaptic to install rmagick and save yourself a
bunch of hassle :slight_smile:

I have fixed the problem above. I am running os x 10.5.6.
I am now getting a different error.

stdint.h is part of the C library. This should be installed along with
a C compiler. Please tell me you’re not trying to compile a C extension
without a C compiler?

Have you tried either the osx installer from rubyforge (automated
build from source: http://is.gd/l6pP ), or have you built the whole
shebang from scratch yourself using http://is.gd/glSd

I followed the second procedure myself with few problems.

Oh sorry, I was a little blind there. So have you checked to see
whether /usr/include/stdint.h exists?

What does the mkmf.log file have to say?

10

Yes. At the end of the os x install instructions are 3 test commands
that all work perfectly.

On Feb 27, 1:08 pm, Charles J.

11

And imagemagick installed without issues?

My conclusion would be, then, that the gem does not like ruby 1.9 just

RMagick works just fine with 1.9.1. I’m waiting for the O.P. to show his
mkmf.log.

I am running Ruby 1.9.1. Does that matter?

This can’t be all of it. It doesn’t include the failure you described in
your post:

checking for stdint.h… *** extconf.rb failed ***

Why don’t you start over and post the output from “gem install” and then
mkmf.log? Also, where did you get the XCode Tools (install disk?
download?), how did you install ImageMagick, and what’s the output from

gcc --version
