Today, I tried to build uClibc snapshot (on June 3, 2010) for mipsel target, and it failed since CPU_CFLAGS was used as host gcc option that includes options for MIPS, like -mips32. Is this known issue or something wrong with my env or config file?
My env is Ubuntu 9.10 x86_64 Bash 4.0.33 make 3.81 gcc 4.4.1 Here is error from "make V=1" set -e; \ tmp=`mktemp ./include/bits/sysnum.h.XXXXXX 2>/dev/null || true`; \ [ -z "$tmp" ] && tmp='./include/bits/sysnum.h.new'; \ KERNEL_HEADERS="stblinux-2.6.31/include/" top_builddir="./" CC="gcc -funsigned-char -fno-builtin -fno-asm -std=gnu99 -mips32 -mtune=mips32 -mabi=32" /bin/sh extra/scripts/gen_bits_syscall_h.sh > $tmp; \ if cmp ./include/bits/sysnum.h $tmp >/dev/null 2>&1; then \ rm -f $tmp; \ else \ mv -f $tmp ./include/bits/sysnum.h; \ fi cc1: error: unrecognized command line option "-mips32" cc1: error: unrecognized command line option "-mabi=32" cc1: error: bad value (mips32) for -mtune= switch cc1: error: unrecognized command line option "-mips32" cc1: error: unrecognized command line option "-mabi=32" cc1: error: bad value (mips32) for -mtune= switch if grep -q __NR_ include/bits/sysnum.h; then true; else \ rm -f include/bits/sysnum.h; \ echo "ERROR: Could not generate syscalls."; \ echo "Make sure that you have proper kernel headers."; \ echo "Your .config in KERNEL_HEADERS=\"\" was set to:"; \ echo "stblinux-2.6.31/include/"; \ exit 1; \ fi ERROR: Could not generate syscalls.
