I'm a bit of a novice at messing around with my environment and I seem to have rather broken it. Many thanks in advance for any assistance you can offer.

The main symptom is that when trying to run rvm install 1.9.3 I get the following trace:

Installing Ruby from source to: /Users/duncanstuart/.rvm/rubies/ruby-1.9.3-p0, this may take a while depending on your cpu(s)...

ERROR: There has been an error while running configure. Halting the installation.

The contents of yaml/configure.log is as follows:

[2012-01-04 02:06:11]  ./configure --prefix="/Users/duncanstuart/.rvm/usr"  
checking for a BSD-compatible install... /usr/bin/install -c

configure: error: in `/Users/duncanstuart/.rvm/src/yaml-0.1.4':

See `config.log' for more details

I suspect the key lines are:

checking for gcc... /usr/bin/gcc-4.2
checking whether the C compiler works... no

The contents of yaml/make.log and yaml/make.install.log are the same (except for the first couple of lines of course)

The contents of the config.log file are included at the end of this question (because it's very long!). The significant line seems to be:

`ld: library not found for -lcrt1.10.6.o`

I get the same errors when running rvm install ... with any other version of ruby, or when trying to install something with Homebrew e.g. brew install wget

My theory

I suspect this has got something to do with incorrectly uninstalling and reinstalling Xcode 3.2.6 - see History below for full details of what I've done.

I've had a look at a ton of stackoverflow posts, but none seem to answer this:

Can't install Ruby under Lion with RVM – GCC issues is closest to my problem, but ultimately seems to be related to Xcode 4
In Error installing Ruby with RVM the author doesn't actually have a c compiler. Problems installing Ruby with RVM: rvm install 1.8.7, rvm install 1.9.2 is probalbly the same.
Make error installing Ruby 1.9.2 via rvm OSX Lion 10.7.2 XCode 4.2 is similar but has different errors in yaml/configure.log

My Setup

I'm running Snow Leopard 10.6.8
I've tried to install Xcode 3.2.6 on 3rd Jan and I think it succeeded
I've got rvm 1.10.0 (the latest version at the time of writing)

The following lines are in /usr/local/bin:

lrwxr-xr-x   1 root       7  3 Jan 02:42 /usr/bin/gcc -> gcc-4.0
-rwxr-xr-x   1 root   93072 23 Sep  2007 /usr/bin/gcc-4.0
-rwxr-xr-x   1 root  166128 24 Oct  2010 /usr/bin/gcc-4.2

If your advice is "upgrade to Lion and install the latest Xcode" then so be it.

History

Here are the steps which I've followed: I'm not sure what's relevant so I'll list it all.

I had a working instance of rvm which was able to successfully install everything up to ruby 1.9.2. I believe I was using Xcode 3.2.6
I had macports installed - I can't remember why.
I had more recently installed Homebrew for some reason or other

When trying to run rvm install 1.9.3 I got an error which I believe was similar to this:

openssl_missing.h:173: error: conflicting types for ‘BN_rand_range’
/usr/local/Cellar/openssl/0.9.8r/include/openssl/bn.h:411: error: previous declaration of ‘BN_rand_range’ was here
openssl_missing.h:177: error: conflicting types for ‘BN_pseudo_rand_range’
/usr/local/Cellar/openssl/0.9.8r/include/openssl/bn.h:412: error: previous declaration of ‘BN_pseudo_rand_range’ was here
openssl_missing.c:270: error: conflicting types for ‘BN_rand_range’
/usr/local/Cellar/openssl/0.9.8r/include/openssl/bn.h:411: error: previous declaration of ‘BN_rand_range’ was here
openssl_missing.c:278: error: conflicting types for ‘BN_pseudo_rand_range’
/usr/local/Cellar/openssl/0.9.8r/include/openssl/bn.h:412: error: previous declaration of ‘BN_pseudo_rand_range’ was here

Googling around suggested that this was some sort of conflict whereby there were two definitions of openssl on the machine (as far as I could understand).
Remembering that there was a warning from Homebrew about conflicts with MacPorts, I tried to uninstall MacPorts using the instructions on the Macports Wiki. I also removed a load of lines related to MacPorts from my .bash_profile
That didn't work and because I didn't understand at all what I was doing, I uninstalled Xcode with sudo <Xcode>/Library/uninstall-devtools --mode=all.
This of course made matters worse and lead to the errors shown above. I therefore reinstalled Xcode from the original CD - this turned out to be Xcode 3.0.
That didn't remove those errors so I tried to uninstall that version of Xcode - unfortunately this requires manually changing the system versions in the uninstall scripts as described here
Finally I downloaded and installed Xcode 3.2.6 (the most recent Xcode available for Snow Leopard?) and have run out of ideas.

config.log

This is the contents of the config.log file - found in /Users/duncanstuart/.rvm/src/yaml-0.1.4/

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by yaml configure 0.1.4, which was
generated by GNU Autoconf 2.67.  Invocation command line was

  $ ./configure --prefix=/Users/duncanstuart/.rvm/usr CC=/usr/bin/gcc-4.2 --no-create --no-recursion

This turned out to be fairly simple in the end - many thanks to everyone in the comments who helped work it out.

There were two issues:

Issue 1: gcc compiler wasn't working

Symptoms:

Functions dependent on gcc fail with the following in the configure log (e.g./Users/<user>/.rvm/log/ruby-1.9.3-p0/yaml/configure.log):

checking for gcc... /usr/bin/gcc-4.2
checking whether the C compiler works... no

...and the following in the config log (e.g. /Users/<user>/.rvm/src/yaml-0.1.4/config.log):

ld: library not found for -lcrt1.10.6.o

Root issue:

Xcode hasn't been installed properly. Specifically the file /Developer/SDKs/MacOSX10.6.sdk/usr/lib/crt1.10.6.o doesn't exist.

Solution:

http://trac.macports.org/ticket/21784: "Try reinstalling Xcode, make sure you choose the "unix development support" option."

Issue 2: RVM wouldn't install ruby 1.9.3

Symptoms:

rvm install ruby 1.9.3 fails with ERROR: Error running 'make '

The corresponding /Users/<user>/.rvm/log/ruby-1.9.3-p0/make.log contains the following segment:

compiling openssl_missing.c
In file included from openssl_missing.c:22:
openssl_missing.h:173: error: conflicting types for ‘BN_rand_range’

openssl_missing.c:278: error: conflicting types for ‘BN_pseudo_rand_range’
/usr/include/openssl/bn.h:412: error: previous declaration of ‘BN_pseudo_rand_range’ was here

Root issue:

Conflicts with previous runs of the install (not entirely sure about this).

Solution

https://rvm.beginrescueend.com/packages/openssl/: clean out the ruby you are trying to install and reinstall:

rvm remove 1.9.3
rvm install 1.9.3

I also removed two other rubies - ruby-1.9.2-p290 and ruby-1.9.2-p136, which might have had something to do with it...:
