Sorry, but you need to create a seperate cross compiler. You're running on a your native system and you're trying to create an executable for another machine. So you need a whole different toolchain. The easiest way *might* be to use buildroot (just google it please) but the point is that you need a whole different setup to target a different machine. gcc, binutils, libc, gdb, the whole banana, and the whole thing has to be specific to the version of the kernel you're running on the target system. Just don't even *try* to figgah out options for your current system. It won't work. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
Hi again, Yes, the question is that I could make a chroot, but I would prefer not to do it for several reasons (hard disk space is one of them). The compiler does his work, the .o are all: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped but then, the ld doesn't manage the situation. The supported emulations are elf_x86_64 elf_i386 i386linux I tried with the last two and it didn't work... The program uses the common standard functions like printf and strcpy and some other features of libreadline. I have both i386 and x86_64 (and again both, binaries and devel packages) installed in my system. Any more clues? Thanks in advance
