How do you generate ELF object file output using g++ compiler?

[Maribeth Romeo]

I am trying to compile a C++ program using g++. I need the object files to be "ELF-64 relocatable object file - PA-RISC 2.0 (LP64)" files. When I use g++ to compile, I end up with "PA-RISC1.1 relocatable object" object files. How can I tell the g++ compiler to change the object file format? I don't have HP's c++ compiler, so I'm stuck with g++. Thanks.

Hi Maribeth,

i don't use g++, but in order to obtain ELF objects in HP's c++ compiler
"+DAportable" option in used.
Maybe something similar in g++?

Well, that's exactly what I'm trying to figure out. I don't know what that option is. I've been pouring over the gcc documentation, but haven't found it yet.

[Piergiacomo Perini]

right, DAportable seems not be a option of g++.
So, try to "googleize" or try this

Maribeth,
-melf according to doc:
"Generate an executable in the ELF format, rather than the default'mmo' format used by the mmix simulalator"

[Maribeth Romeo]

That's not an option for HP-UX. The doc says, "-melf - Legacy no-op option only recognized with the cris-axis-elf and cris-axis-linuxgnu targets."

If you type "gcc -melf my.c" on the command line, you will get "invalid options 'elf'"

This doesn't seem like an unreasonable thing to do, does it?

You'll need 64-bit version of gcc. One place you can it from is http://www.hp.com/go/gcc, click on 'GCC for HP-UX' link and download HP-GCC PA-RISC LP64 (either 3.x or 4.x).

Hello,

You need to download 64 bit GCC for generating 64 bit objects. Default GCC what you download is capable of generating 32 bit objects. You can download from,

http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,7663,00.html

Remember to download 64 bit version. It is HP Supported GCC.

You have to use +DA2.0 option with aCC or cc compiler.

You are all right. I chose to use aCC only because of time constraints. I have to pay for it, but it is probably quicker than getting another version of gcc. Thanks to all of you.
