-----------\>8-------------

I can “fix it” changing -Ae for -Aa, but when the building process  
runs miniruby to run every extconf.rb, it breaks in lib/mkmf.rb saying  
a block was not given to checking\_for (when checking for the existence  
of windows.h), which is non sense.

Any idea?

Is the stdio.h in error itself, or did Ruby override something it  
shouldn’t  
have?

Does it go away with 1.8.3 or 1.8.4-preview1 ?

And probably most important, is vsnprintf missing on hpux 10? if not,  
why  
does ./configure seem to think so?

I have not seen this problem with 1.8.1 or 1.8.4-preview1 on HP-UX 11  
(though comforting, that may be of very little help to you)

Bye,  
Kero.

I’m new at HP-UX, I’m missing something important for sure. Changing  
the flag -Ae for -Aa “solves” the problem for vsnprintf.c. But then I  
get other errors when running miniruby.

> Does it go away with 1.8.3 or 1.8.4-preview1 ?

I’ll try with 1.8.4-preview1 and see

Yes, it is missing.

HP-UX 11 already has vsnprintf AFAIK.

I have just found this:

[http://www.ruby-lang.org/ja/install.cgi?cmd=view;name=HP-UX](http://www.ruby-lang.org/ja/install.cgi?cmd=view;name=HP-UX)

It explains how to solve some problems I ran into. It says something  
about vsnprintf and a patch for HP-UX, but I can’t read Japanese ☹  
Does any caritative soul want to help me? (from the line starting with  
“missing/vsnprintf.c”, almost at the end of the file)

Thanks in advance

(Kero: I tried 1.8.3 and it was the same)

I manually applied the patch to ruby-1.8.3/missing/vsnprintf.c and it
