Hi, The linux-mips.org Web site recommends gcc 3.4.4 to build the MIPS kernel. However: <<<<<<<<<<<<<<<<<< [dmitri.vorobiev@amber linux-2.6]$ mips-unknown-linux-gnu-gcc -v Reading specs from /home/dmitri.vorobiev/Projects/misc/zoo/lib/gcc/mips-unknown-linux-gnu/3.4.4/specs Configured with: ../src/gcc-3.4.4/configure --prefix=/home/dmitri.vorobiev/Projects/misc/zoo --target=mips-unknown-linux-gnu --disable-nls --without-headers --with-gnu-ld --with-gnu-as --disable-shared --disable-threads Thread model: single gcc version 3.4.4 [dmitri.vorobiev@amber linux-2.6]$ make ARCH=mips CROSS_COMPILE=mips-unknown-linux-gnu- CHK include/linux/version.h CHK include/linux/utsrelease.h CALL scripts/checksyscalls.sh CC init/main.o include/asm/bitops.h: In function `start_kernel': include/asm/bitops.h:76: warning: asm operand 2 probably doesn't match constraints include/asm/bitops.h:76: warning: asm operand 2 probably doesn't match constraints include/asm/bitops.h:76: warning: asm operand 2 probably doesn't match constraints include/asm/bitops.h:76: error: impossible constraint in `asm' include/asm/bitops.h:76: error: impossible constraint in `asm' include/asm/bitops.h:76: error: impossible constraint in `asm' make[1]: *** [init/main.o] Error 1 make: *** [init] Error 2 [dmitri.vorobiev@amber linux-2.6]$ <<<<<<<<<<<<<<<<<< Kernel build goes smoothly for me with this gcc version: <<<<<<<<<<<<<<<<<< [dmitri.vorobiev@amber linux-2.6]$ mips-unknown-linux-gnu-gcc -v Using built-in specs.
