CPAN error when compiling C code

[ken kroel]

greetings,

i'm trying to setup CPAN on our HP 9000, HP-UX 11.0. i run into an error whenever i try to install a module that contains C code:

cc1: Invalid option `-fno-strict-aliasing'
*** Error exit code 1

i saw this when installing LWP to get CPAN past our firewall, but worked around it by removing the option from the makefile. is there a way to tell CPAN to remove this option from all its makefiles? or would it be better to upgrade our gcc so it recognizes the option? we do have the standard HP cc compiler, can i tell CPAN to use that? IIRC, i have to use the same compiler that perl used, which is gcc. if we need to upgrade gcc, is it fairly simple or are there known problems? any advice is appreciated. TIA

ken

Hi,

compiling perl modules or other freeware stuff is seldom successful with the original HP-UX cc. All makefiles are designed for gcc.

Since the HP-UX porting center discontinued the 11.00 branch, you can get latest gcc for HP-UX 11.00 from http://mirrors.develooper.com/ .

I successfully compiled perl modules via CPAN with an gcc 3.3.2 on a HP-UX 11.00 system. Since we have an internal CPAN mirror, I have no hassle with any firewalls :-)

Try this:
http://hpux.connect.org.uk/hppd/hpux/Gnu/gcc-3.4.3/

Pay attention to downloading and installing all pre-requisites.

This stuff can be compiled under hpux cc with changes, but its hardly ever worth the trouble.

thanks for the replies. i was able to download and install gcc3.4.2, but ran into trouble when i tried replacing the existing gcc 2.7.2.3.

i tried just replacing the gcc executable, but it complained loudly, so i obviously missed switching other things. how can i find out what needs to be replaced/renamed/relinked, etc, to get the new version working?

it installed in /usr/local/pa20_64/bin/gcc

the following are the results of trying to install a module in CPAN, after the switch:
