I’m trying to get ruby running on AIX 5.3 as I can’t find any  
precompiled versions… 😉

I’ve installed the following rpms:

- openssl-0.9.7l-1
- libgcc-4.0.0-1
- zlib-1.2.3-3
- gcc-c+±4.0.0-1
- gcc-4.0.0-1
- libstdc+±4.0.0-1
- libstdc+±devel-4.0.0-1
- zlib-devel-1.2.3-3
- openssl-devel-0.9.7l-1

I set my path to  
/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/usr/java14/jre/bin:/usr/java14/bin:/opt/freeware/bin/

I tried a simply ./configure as well as ./configure  
–prefix=/usr/local/ruby/ruby-1.8.6 --disable-ipv6  
–with-openssl-include=/opt/freeware/include/openssl  
–with-openssl-lib=/opt/freeware/lib  
–with-zlib-include=/opt/freeware/include  
–with-zlib-lib=/opt/freeware/lib to no avail.

Here’s a snippet of the make with a number of errors:  
gcc -g -O2 -DRUBY\_EXPORT -I. -I. -c array.c  
gcc -g -O2 -DRUBY\_EXPORT -I. -I. -c bignum.c

Any help would be greatly appreciated!

It seemed that you’ve installed gcc for AIX 5.1 to AIX 5.3.  
I was able to recreate this error using gcc for 5.1 in my test  
environment(AIX5.3).  
Please install correct version of gcc.  
You can download them from  
ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/gcc
