HI all, I run "make obj" and try to make cross-tools again. looks a variable errors are caused same factor. every target failed in generating _muldi3.o from libgcc2.c.
for example, in sparc64 target, last command which cause error occured is follow. /usr/src/gnu/usr.bin/cc/libgcc/obj.i386.sparc64/../cc/cc -B /usr/src/gnu/usr.bin/cc/libgcc/obj.i386.sparc64/../cc1 -c -O2 -pipe -g -DIN_GCC -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -DHAVE_GTHR_DEFAULT -I/usr/src/gnu/usr.bin/cc/libgcc/../../../gcc/include -I/usr/src/gnu/usr.bin/cc/libgcc/../../../gcc/gcc/config -I/usr/src/gnu/usr.bin/cc/libgcc/../../../gcc/gcc -I. -I/usr/src/gnu/usr.bin/cc/libgcc/../cc_tools -DIN_GCC -DHAVE_CONFIG_H -DPREFIX=\"/usr\" -DCROSS_COMPILE -I/usr/src/gnu/usr.bin/cc/libgcc/obj.i386.sparc64/../cc_tools -I/usr/src/gnu/usr.bin/cc/libgcc/../cc_tools -I/usr/src/gnu/usr.bin/cc/libgcc/../../../gcc/gcc -I/usr/src/gnu/usr.bin/cc/libgcc/../../../gcc/gcc/config -I/usr/src/gnu/usr.bin/cc/libgcc/../../../gcc/include -I/usr/src/gnu/usr.bin/cc/libgcc/../../../gcc/libcpp/include -I/usr/src/gnu/usr.bin/cc/libgcc/../../../gcc/libdecnumber -fPIC -DL_muldi3 -o _muldi3.o /usr/src/gnu/usr.bin/cc/libgcc/../../../gcc/gcc/libgcc2.c I added -v option for cc, and run above command. output is follow. --- Using built-in specs.
