Thanks. I instilled gcc and ran configure. It received and error, so I  
checked the config.log and found this:

gcc version 4.1.0  
configure:1972: $? = 0  
configure:1974: gcc -V \</dev/null \>&5  
gcc: ‘-V’ option must have argument  
configure:1977: $? = 1  
configure:2000: checking for C compiler default output file name  
configure:2003: gcc conftest.c \>&5  
ld: I/O error, file “unix98.o”: No such file or directory  
Fatal error.

Any Suggestions?

I would have stuck with the tried-and-true gcc 3.4 series instead of the  
more strict gcc 4.x series. I don’t know which gcc matz uses, but I  
doubt  
it’s 4.1.

That said, I think these links discuss the unix98.o linking problem:  
[http://devrsrc1.external.hp.com/STKT/impacts/i332.html](http://devrsrc1.external.hp.com/STKT/impacts/i332.html)  
[http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/95163](http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/95163)

To fix the linking problem I would try the following:

1. revert to gcc 3.4.5
2. add environmental variable definitions as specified in above links
3. add ‘-L/usr/lib’ so gcc knows where unix98.o is located. Something  
like this:  
export LIBARY\_PATH=“/usr/lib:/usr/local/lib:/lib:.”
4. copy /usr/lib/unix98.o to your ruby compilation directory if all else  
fails.

The error at ‘configure:1974’ is inconsequential. The error at  
‘configure:2003’  
is important.

I’m sorry I don’t have access to an hp system to test any of this on.
