Help on compiles

['David Scott Urban]

I meant to send this as a general reply to the list not a private reply:

The problem he is seeing is not with the gcc installation or gcc itself. It is 
with the Makefile he is using. It is trying to invoke the gcc compiler with 
flags that are for the HP Ansi-C compiler. The HP compiler uses a + instead of a 
- sign for invoking optimizations. The only optimization flag it recognizes with 
a - sign is -O which is the default and equivalent to +O2. The +DAportable flag 
allows the code to be compiled on either PA-Risc 1.1 or PA-Risc 2.x and run on 
both architectures. He will need to look up the gcc flags in the documention, 
man pages, info pages or ask HP support what flags are equivalent to the HP C 
compiler flags.

>> Ricardo, here are some answers to your questions:

>> The system is HP-UX 11.00, 64-bit
