Re: Problem with 64-bit Postgres

Hmm, i just tried to do the same thing (ppc64 sh, ...) but it seems to me
that the result is a 32bit executable:

When i compiled with the -m64 switch the result was an ELF64 file, and all
of the library references were going to /lib64/ ...

What elf-class did your compilation produce? Is my assumption, that it
should be elf64 for a 64-bit executable correct?
