Hi All, I have the following 64-bit linking problem with a device driver:
$ gcc -D_KERNEL -m64 -mcmodel=kernel -mno-red-zone -ffreestanding -nodefaultlibs -c driver-test.c $ ld -r -o driver-test driver-test.o [b]ld: Relocatable linking with relocations from format elf64-x86-64 (driver-test.o) to format elf32-i386 (driver-test) is not supported[/b] I am running a 64-bit OpenSolaris 2008.11. Even though 32-bit drivers compile fine, they cannot be loaded: $ gcc -D_KERNEL -ffreestanding -nodefaultlibs -c driver-test.c $ ld -r -o driver-test driver-test.o $ cp driver-test /tmp $ cat driver-test.conf name="driver-test" parent="pseudo"; $ cp driver-test.conf /tmp $ ln -s /tmp/driver-test /usr/kernel/drv/driver-test $ ln -s /tmp/driver-test.conf /usr/kernel/drv/driver-test.conf $ add_drv driver-test No 64-bit version of (driver-test) found; 32-bit version of this driver exists. [b]32-bit driver (driver-test) not loadable on 64-bit kernel.[/b] System configuration files modified but driver-test driver not loaded or attached. Forcing ld to output in 64-bit format gives more puzzling results: $ ld --oformat elf64-x86-64 -r -o driver-test driver-test.o [b]ld: Relocatable linking with relocations from format elf64-x86-64 (driver-test.o) to format elf64-x86-64 (driver-test) is not supported[/b] I followed the "Device Driver Tutorial" book as closely as possible. Google did not turn up anything useful. Any help would be appreciated. Thanks! Cheers, Rouslan -- This message posted from opensolaris.org
