Hi, I've been trying to modify the UML makefiles in the 2.6.23.9 kernel to compile against a different C library, but I'm running into trouble getting parts of UML to compile with GCC 4.2.1. In particular, files in os-Linux that use functions like __uml_setup are causing GCC to throw errors.
For example, when I try to compile arch/um/os-Linux/aio.c in my environment, I get the following: gcc-4.2.1-rev -Wp,-MD,arch/um/os-Linux/.aio.o.d -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Os -D__arch_um__ -DSUBARCH=\"i386\" -Dvmap=kernel_vmap -Din6addr_loopback=kernel_in6addr_loopback -Din6addr_any=kernel_in6addr_any -march=i686 -mpreferred-stack-boundary=2 -ffreestanding -D_LARGEFILE64_SOURCE -fno-unit-at-a-time -fno-omit-frame-pointer -fno-optimize-sibling-calls -g -fno-stack-protector -Wdeclaration-after-statement -Wno-pointer-sign -Iarch/um/include -I/home/tmjackso/build/orchestra/uml/linux-2.6.23.9/arch/um/include/skas -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -DHAVE_AIO_ABI -v -nostdinc -I../../dietlibc/trunk/include -isystem /usr/local/gcc-4.2.1-rev/include -c -o arch/um/os-Linux/aio.o arch/um/os-Linux/aio.c arch/um/os-Linux/aio.c:307: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘__attribute_used__’ arch/um/os-Linux/aio.c:307: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘__attribute_used__’ arch/um/os-Linux/aio.c:350: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘__attribute_used__’ arch/um/os-Linux/aio.c:360: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘__attribute_used__’ I know that __uml_setup and friends are defined in arch/um/include/init.h and it is being included, but it seems like GCC is not using it. If I comment out __uml_setup, other files which have functions starting with two underscores like __uml_initcall also cause compilation to fail. Can anyone give some hints to solve this problem?
