How do I set the 'cc' compiler for my session?

[Larry Finnegan]

I am installing the Oracle 9.2.0.6 patch set on an Itanium (HP-UX 11.23) and when the installer got to the linking phase, I got these errors:

I know that these refer to the limitations of the bundled compiler for use in building the kernel. I have GNU gcc installed on this system and would like to try using it to complete the Oracle installation. How do I tell my environment to use gcc instead of the bundled cc? I'm using Bash as my shell. Would just exporting:

CC=/path/to/gcc

work?

Hi Larry,
try adding to environment variable PATH also the gcc path.
just a guess

Hi Larry ,

Try to check the Oracle 9.2.0.6 patch script , how its calling the cc program , you can accordingly replace it by gcc location.

cheers,
Raj.

[Larry Finnegan]

Hmmm... the link that HAKAN posted is a little disconcerting since it implies that Oracle must be compiled with the HP C compiler and not 'gcc'. I've cross posted to the forums at Oracle to see if this is the case. I'd hate to have to buy a compiler just to install an update. :(

[Florian Heigl (new acc)]

export CC=/path/to/gcc is just right,
I'd also set some more things:

CPP=/usr/local/bin/cpp
CXX=/usr/local/bin/g++
(or whereever these reside)


- but I've never linked Oracle on HP-UX using gcc; but I've done it on linux without problems, so it should work. Check You're using a multithreaded gcc build with gcc -v, I don't know if it'll break anything if it isn't multithreaded.

[Larry Finnegan]

Oracle Support confirmed for me that they do not recommend using 'gcc' for linking the Oracle binaries. It must be the HP C Compiler. So now I need to figure out how many thousands of dollars this is going to cost... Ugh.

[Jon M Zellhoefer]

The HP C Compiler comes with the OS - you'll only end up paying thousands if you need ANSI-C ... you can get an idea of cost via the software depot.
